Added flags parameter to register_property method

- flags parameter is set by default to vtable::property_::emits_change
- with this change user can set parameter to vtable::property_::none
to avoid sending property change signal for greater performance
- added example/register-property.cpp with example application
which uses new functions

Tested:
- run openbmc tests with this change, no regression detected
- tested that default behaviour (property_::emits_change) is working as intended
- tested that properties still signal change when emit_change flag is used
- tested that properties doesn't signal change when no emit_change flag is used
- tested that const flag is passed and handled corretly
- verified that performance of application increases when emit_change flag turned off

meson: create structure for use as submodule

Some other openbmc projects have set up sdbusplus to use as a
meson-subproject. When porting one of them (entity-manager) to use
the meson build, I realized we are not structuring our meson.build
file according to best-practices for consumption as a submodule.
Specifically, we are missing the 'sdbusplus_dep' variable as described
in the meson reference: https://mesonbuild.com/Subprojects.html

Now that 'sdbusplus_dep' is defined, use it throughout the rest of
the meson.build files as well for simplification.

sdbus++: Generate initial client header

By "client-header" option, sdbus++ could generate a client header file
that provides the code used by the client.

Currently it only includes the interface name's string in the header
file, it could be extended in the future.

The client header could be merged together for all the interfaces, so
that an interface library could provide a single header to represent all
the interface strings.

Usage:

sdbus++ -r $(srcdir) -t $(top_builddir)/tools/sdbusplus/templates \
interface client-header <interface>

Tested: Generate the header in example and use static_assert to verify
it is the same as the interface defined in the interface calss.

capture so that the lambda takes over the parameter and
we can modify it after the async callback.

asio: Allow mutable lambdas + small cleanup

There are many cases in which we want to have a mutable
capture so that the lambda takes over the parameter and
we can modify it after the async callback. By making the
top level lambda mutable, the users callback can be mutable.

Also remove a couple references to experimental and a copy
that I saw when I was fixing this issue.

Tested: Added test and made sure that refish which uses
many async_method_calls still worked fine

Change async_method_call to be no-throw

The async_method_call() would throw despite the inferred promise that it
would not, because the handler would be passed an error_code object. But
that would only protect from the dbus method call itself. When it came
time to unpack the response, the read_into_tuple(...) method call would
throw if the received types did not match the expected types. And
because this throw would happen in a separate boost::asio context, the
throw would always be fatal. Now, any exception during the D-Bus call or
unpacking of parameters will result in an error_code getting passed into
the handler so it can take appropriate action.

This also updates the example to remove try/catch statements around the
async_method_call and yield_method_call examples and shows what happens
if the method calls fail because of different types of errors
(api/function does not exist vs. incorrect unpack types).

Tested-by: run asio-example to see that it works as expected:

When it came time to unpack the response, the read(...) method call

the method forces you to pass in an error_code and it will always return
the appropriate error instead of throw.

Add sdbusplus::asio coroutine method handling

Adding the server-side of the coroutine path allows yielding
asynchronous method handling via coroutines. This means that a method
handler can call a yielding dbus call (or other asio-based asynchronous
call) without blocking the rest of the process.

The call path might look something like this:

service.thing/object/path/interface.my-method()
- do something
- yield_method_call(other.service, /other/path,
other.interface, other-method)
<yields to other coroutine>

execute other code in another context

<returns some time later with dbus call's response>
- use response from other method
<- return my-method response

This also changes the asio-example, pulling it apart into a
client/server model so it is more clear about how to use the yielding
async method handling and yielding async method calls.

Add coroutine support for sdbusplus::asio method calls

Using a coroutine to asynchronously execute method calls gives the best
of both worlds:
1) better readability because the code reads like synchronous code
2) better throughput because it is actually asynchronous

When passed in a boost::asio::yield_context, the sdbusplus::asio dbus
connection members async_send and async_method_call will execute
asynchronously using coroutines.

This also adds an example of how this works in the

superior asynchronous eventing, but not want to rewrite all the existing
sd_event code. This gives us the best of both worlds, with a
low-overhead mechanism to handle the sd_events.

automatically extracted arguments.

This means that the registration mechanism as well as the callback
mechanism need to be aware of a 'message as a first parameter' situation
and behave accordingly. The registration needs to strip the message
parameter off in order to expose a correct DBus signature. The callback
mechanism needs to strip of the message parameter in order to properly
unpack the message, but add it back in before calling apply to execute
the function.

Tested: Added an example to example/asio-example.cpp and checked to see
that it builds. Was able to extract sender from message passed
into the IPMI handler.
