log: Add test case for logging code

This gives us a baseline of how the SPICE/glib integration is supposed
to behave.

Everything goes through glib logging facilities, and is impacted by
G_MESSAGES_DEBUG/G_DEBUG=fatal-{warnings,criticals}

Messages in the SPICE_LOG_DOMAIN log domain (output either through
spice_log() or g_log()) will also consider the legacy SPICE_DEBUG_LEVEL
and SPICE_ABORT_LEVEL environment variables. Messages in other domains
will not be impacted by these legacy environment variables.

If spice-common is built without SPICE_DISABLE_ABORT,
spice_return_if_fail()/spice_critical() will abort the program.
g_return_if_fail()/g_critical() will not abort the program.
