Reformat meson files with meson format

Meson recently got a new format command in 1.5.0 [1]. It makes slightly
different formatting decisions compared to muon (what we used
previously) but given it's the official tool, we should switch to it.

There is one bug resolved recently that requires this format be done
using the meson from master.

Ideally this would be enforced by CI in the future, but that's WIP.

Tested: Whitespace only, code compiles.

Add a Hypervisor Computer System Option

Today to determine if the hypervisor computer system resource should be
added to the System Collection a call to the Settings Manager is made.

Based on discussion in
https://gerrit.openbmc.org/c/openbmc/bmcweb/+/73203 and to help the
multihost stuff move forward, lets move this hypervisor under a meson
option which any company that needs can enable. I think IBM is the only
one who uses this so the risk of breaking someone should be small.

One day hope to converge at some point, this probably doesn't happen
until after the multihost stuff goes in.

This is also better for implementations that don't have this backend
because now routes like
/redfish/v1/Systems/hypervisor/EthernetInterfaces/ aren't put out. I.e.
a call to /redfish/v1/Systems/hypervisor/EthernetInterfaces/ is now
going to return 404 instead of 500 on systems without this backend
support.

Tested: Enabled this and see the hypervisor system. Without this enabled
do not see the hypervisor system. No new validator errors either way.

Mutual TLS parsing change at runtime

Redfish AccountService[1] defines methods for selecting how to map a
certificate CommonName attribute to a user. These are intended to be a
patch parameter.

This commit implements the Redfish defined schemas; The parsing mode is
stored in the bmcweb persistent configuration file as an integer enum,
with Mapping to the Redfish schema.

To handle OEM specific parsing modes, an enum value of 100+ is defined
to allow the additional OEM parameters. Unfortunately, Redfish doesn't
have a way to represent these today, so those modes are currently not
selectable at runtime.

Now that things are runtime selectable, this obsoletes the option
mutual-tls-common-name-parsing, as it is not longer required at compile
time.

Tested:
GET /redfish/v1/AccountService

Allow configuring "bmc" and "system"

In the early days of bmcweb, we made two pretty critical assumptions;
First, is that a given platform would only have a single BMC instance
(represented as "bmc") and a single host instance (represented as
"system").
Second we assumed that, given that Redfish suggests against hardcoding
URIs in client implementation and leaves them freeform, clients would
code to the standard.

Our own webui-vue hardcodes Redfish URIs [1], and the documentation is
littered with examples of hardcoded curl examples of hardcoding these
URIs. That bug was filed in 2020, and the issue has only gotten worse
over time.

This patchset is an attempt to give a target that we can start solving
these issues, without trying to boil the ocean and fix all clients in
parallel.

This commit adds the meson options
redfish-manager-uri-name
and
redfish-system-uri-name

These are used to control the "name" that bmcweb places in the fixed
locations in the ManagerCollection and ComputerSystemCollection schemas.

Note, managers is added, but is not currently testable. It will be
iterated on over time.

Tested:
Changed the URL options to "edsbmc" and "edssystem" in meson options.

Redfish service validator passes.
URLs appear changed when walking the tree.

Bring consistency to config options

The configuration options that exist in bmcweb are an amalgimation of
CROW options, CMAKE options using #define, pre-bmcweb ifdef mechanisms
and meson options using a config file. This history has led to a lot of
different ways to configure code in the codebase itself, which has led
to problems, and issues in consistency.

ifdef options do no compile time checking of code not within the branch.
This is good when you have optional dependencies, but not great when
you're trying to ensure both options compile.

This commit moves all internal configuration options to:
1. A namespace called bmcweb
2. A naming scheme matching the meson option. hyphens are replaced with
underscores, and the option is uppercased. This consistent transform
allows matching up option keys with their code counterparts, without
naming changes.
3. All options are bool true = enabled, and any options with _ENABLED or
_DISABLED postfixes have those postfixes removed. (note, there are
still some options with disable in the name, those are left as-is)
4. All options are now constexpr booleans, without an explicit compare.

To accomplish this, unfortunately an option list in config/meson.build
is required, given that meson doesn't provide a way to dump all options,
as is a manual entry in bmcweb_config.h.in, in addition to the
meson_options. This obsoletes the map in the main meson.build, which
helps some of the complexity.

Now that we've done this, we have some rules that will be documented.
1. Runtime behavior changes should be added as a constexpr bool to
bmcweb_config.h
2. Options that require optionally pulling in a dependency shall use an
ifdef, defined in the primary meson.build. (note, there are no
options that currently meet this class, but it's included for
completeness.)

Note, that this consolidation means that at configure time, all options
are printed. This is a good thing and allows direct comparison of
configs in log files.

Tested: Code compiles
Server boots, and shows options configured in the default build. (HTTPS,
log level, etc)

Consolidate Vm implementations

As much as the two vm implementations SEEM different, the differences
largely lie in how we're getting the nbd proxy socket. One is relying
on launching a process (nbd-proxy), the other is getting the fd from
dbus. Given [1] exists and is in process, we need to have a plan for
getting these two VM implementations into one, once that patchset is
complete.

This commit: Splits the vm-websocket option into vm-websocket-provider,
providing two options, nbd-proxy, and virtual-media (the names of the
respective apps). To accomplish this, it moves the contents of
nbd-proxy into include/vm-websocket, so we can compare the similarities
and start consolidating.

The longer term intent is that the nbd-proxy option will be completely
removed, and the code deleted. This has the additional advantage that
we will no longer require the boost::process dependency, as all info
will be available on dbus.

As part of this, the nbd proxy websocket is also registered at /vm/0/0,
to be backward compatible with the old interfaces.

Tested: Code compiles. Need some help here.

This macro came originally from CROW_ENABLE_SSL, and was used as a macro

OpenSSL has been pulled into many other dependencies, and has been

reason to hold onto this macro.

Remove most uses of the macro, and for the couple functional places the

mutual-tls: Add support for Meta certificates

Meta Inc's client certificates use an internal Subject CN format

Commit adds the `mutual-tls-common-name-parsing=meta` option to, on
Meta builds, parse the Subject CN field and map either the <entity>
to a local user.

The <type> field determines what kind of client identity the cert
represents. Only type="user" is supported for now with <entity> being
the unixname of a Meta employee. For example, the Subject CN string
below maps to a local BMC user named "kawmarco":

Subject CN = "user:kawmarco/dev123.facebook.com"

Fix logging

The recent change to logging has caused a couple of bugs. First, when
building within yocto, the complete path is now returned on log
messages. This is wasteful of speed, and not super helpful to
developers to have a full path. Per the discussion on the original
patchset, drop this down to just the filename.

2, because of it's use as a pseudo log level, "enabled" is in the list
of strings. This causes an index mismatch, which causes logs to be
logged at the wrong level beyond debug. Move the entry to the end to
fix this.

Third, move the logging of level to upper case, to follow the old
convention.

HTTP/2 support

HTTP/2 gives a number of optimizations, while keeping support for the
protocol. HTTP/2 support was recently added to the Redfish
specification. The largest performance increase in bmc usage is likely
header compression. Almost all requests reuse the same header values,
so the hpack based compression scheme in HTTP/2 allows OpenBMC to be
more efficient as a transport, and has the potential to significantly
reduce the number of bytes we're sending on the wire.

This commit adds HTTP2 support to bmcweb through nghttp2 library. When
static linked into bmcweb, this support adds 53.4KB to the bmcweb binary
size. nghttp2 is available in meta-oe already.

Given the experimental nature of this option, it is added under the
meson option "experimental-http2" and disabled by default. The hope is
to enable it at some point in the future.

To accomplish the above, there a new class, HTTP2Connection is created.
This is intended to isolate HTTP/2 connections code from HttpConnection
such that it is far less likely to cause bugs, although it does
duplicate about 20 lines of code (async_read_some, async_write_some,
buffers, etc). This seems worth it for the moment.

In a similar way to Websockets, when an HTTP/2 connection is detected
through ALPN, the HTTP2Connection class will be instantiated, and the
socket object passed to it, thus allowing the Connection class to be
destroyed, and the HTTP2Connection to take over for the user.

Add an option flag for multi-computersystem

A number of discussions have occurred, and it's clear that
multi-computer system is not a transition that can be done in a single
series of commits, and needs to be done incrementally over time. This
commit adds the initial option for multi-computer system support, with
an option flag that can be enabled when the new behavior is desired.
This is to prevent needing a long-lived fork.

This option operatates such that if enabled, all ComputerSystem route
options will now return 404. This is to allow the redfish service
validator to pass, and to be used for incremental development. As the
routes are moved over, they will be enabled, and service validator
re-run.

Per the description in the meson options, this option flag, and all code
beneath of it will be removed on 9/1/23. The expectation is that by
this date, given the appropriate level of effort in implementation,
there will be no code remaining under that option flag. After this
date, code beneath this option flag will be removed.

Tested: No functional changes without option.

With option enabled, /redfish/v1/Systems produces no entries.
Spot check of various routes returns 404.

Redfish service validator passes.

Initially I tried to fix the summary status issues,
(https://gerrit.openbmc.org/c/openbmc/bmcweb/+/60663)
But later it was decided that we should also remove these attributes
from the bmcweb code. Here is a link to discussion on discord:

This drop hides these attributes under defined
BMCWEB_ENABLE_PROC_MEM_STATUS. This option is disabled by default.

These attributes will be permanently removed from code in 1Q 2024
(in 8-9 months).

Testing:
- Redfish validator passed excepted couple of failures but those are
failing without my changes too.
- Make sure that summary status for memory and processor is not seen

health: Add option to disable health-populate

The Health populate calls GetManagedObjects at `/` which can take a lot
of time. Add the option to disable to improve performance if it is not
needed.

health: Add option to disable health-populate

The Health populate calls GetManagedObjects at `/` which can take a lot
of time. Add the option to disable to improve performance if it is not
needed.

Tested:
```
$ meson build -Dhealth-populate=disabled
...
User defined options
backend : ninja
health-populate : disabled
```

Build passed.

Health Status removed. Some resource still create HealthPopulate, but
does not populate. It will require further refactoring to clean it out.

Update Logging option for the setting log level

In order to be able to more easily debug bmcweb related issue,
a new meson option is added to set a specific logging level
Which generates the targeted logging traces rather than all of
debug traces.

The current option -Dbmcweb-logging which can be either
disabled or enabled is changed to allow to set the log level
for the specific level traces (e.g. error or critical traces)
to be written to the journal.

-Dbmcweb-logging=<log-level>

where <log-level> can be disabled, enabled, debug, info,
warning, error, or critical.

- `disabled`: Turns off all bmcweb log traces.
- `enabled` : treated as `debug`
- Other option can be described in
[Logging Levels](DEVELOPING.md).

For an example, to enable only 'error', 'critical' log
entries, bmcweb can be built with

-Dbmcweb-logging=error

Testing:
- Verified that only the specific logs (e.g. error and
critical logs) were displayed by compiling bmcweb with the
specific bmcweb-logging level.
