gmessages: Add a structured logging API

Browse Source 
In parallel with g_log(), add a new structured logging API, based around
g_log_structured() and various helper functions which are exposed
publicly to allow programs to build their own logging policies easily,
without having to rewrite a lot of gmessages.c because it’s all
internal.

See the expanded documentation at the top of gmessages.c for some
rationale. See the g_log_structured() documentation for some example
code.
