sdbus++: error: move error to front of namespace

To be consistent with the new 'server' and 'client' namespaces,
refactor the 'error' namespace in the same way. Move 'error' to
the front and use snake_case for namespace and struct identifiers.
Leave the same backwards compatibility, which can be disabled with
the SDBUSPP_REMOVE_DEPRECATED_NAMESPACE guard.

sdbus++: change binding namespace format

Change the generated binding namespace name such that the interface
`xyz.openbmc_project.Foo` becomes
`sdbusplus::server::xyz::openbmc_project::Foo` instead of
`sdbusplus::xyz::openbmc_project::server::Foo`. This both simplifies
the namespace generation and makes the correlation from interface to
binding name much more obvious.

An alias namespace to the old name is still generated so that users
have a chance to migrate.

Remove dead code paths

There's a few places where we call return after another return
statement, or after a method that doesn't return. These are not
required, and can be removed.

bus: utility to process messages in infinite loop

This change introduces a simple function for synchronous DBus servers to
start listening to incoming requests and run forever.

This can avoid duplicate while loops in server codes across repos.

Please see the following change for context.

Tested: the calculator server unit test passed.

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.
