network: Suppress reporting an error when D-Bus is unavailable in networkStateInitialize()
When the network driver initializes itself, it tries to subscribe
to signals from Firewalld sent over system D-Bus. Well, the code
is written in best effort mode, i.e. lack of D-Bus is not
considered an error. Problem is, virGDBusGetSystemBus() which is
used to obtain system D-Bus prints out an error in case of
lacking system D-Bus. This pollutes the logs (which may mislead
users) and goes against the best-effort nature of aforementioned
code. Check for the system D-Bus presence via
virGDBusHasSystemBus() first.

remote_driver: Move URI arg extraction into a separate function
There's a problem with glib: what we might consider functions are
in fact macros and to make things worse - they do declare local
variables. For instance here's the declaration of
g_clear_pointer() macro:
Now, as of v6.2.0-rc1~267 our VIR_FREE() macro is in fact a
redeclaration of g_clear_pointer(). Thus, calling VIR_FREE()
increases stack size!
Ideally, this wouldn't be a problem, because those variables
(_pp, _ptr) live in their own block. And clever compiler can just
reuse space created for one block.
But then there's clang where we are hitting this exact problem in
functions like doRemoteOpen() where either g_clear_pointer() is
called directly, or there are macros like EXTRACT_URI_ARG_STR()
which hide the call away.
That's why despite our previous efforts decreasing stack size we
still needed v9.8.0-rc1~208.
Well, moving URI argument extraction (those calls to
EXTRACT_URI_ARG_* macros) into a separate function helps us
decrease stack size from 2296 bytes to 1320.
Even after this there are still more possibilities for
improvements, but those will be addressed in future commits.
