[Qemu-devel] [PATCH 0/3] glib: move compat functions into glib-compat.h

[Stefan Hajnoczi]

glib has deprecated APIs like GStaticMutex, g_thread_create(), and others.  In
QEMU support both old and new APIs since using deprecated APIs would flood us
with warnings but legacy distros must continue to build the QEMU source code.

This patch series reduces ifdefs by moving glib compat functions into
glib-compat.h, where they can be reused.

There are two strategies for compat functions:

1. Implement the new API using the deprecated API.  This compat function is
   used when building on a legacy host.  Sometimes the API semantics are so
   different that this option is not feasible.

2. Add a new wrapper API that maps to the deprecated API.  The wrapper is not
   marked deprecated so it works as a drop-in replacement but is implemented
   using the new API where possible.

  glib: move g_poll() replacement into glib-compat.h
  glib: add g_thread_new() compat function
  glib: add compat wrapper for GStaticMutex
