Overview of changes in GLib 2.73.2

• Replace PCRE1 with PCRE2: This is a major change to drop the libpcre1
  dependency and use libpcre2 instead, while preserving the behaviour and API of
  GRegex. G_REGEX_OPTIMIZE and G_REGEX_JAVASCRIPT_COMPAT are now deprecated
  and became a no-op, while other flags are adapted accordingly to the new API
  (work by Aleksei Rybalkin, Philipp Withnall) (!2529, #1085)

• Preserve destruction order in gdataset, fixing various crashes during
  objects disposal (work by Peter Bloomfield) (!2776, #2672, #2676)

• Require C99 __VA_ARGS__ (work by Emmanuele Bassi) (!2791, #2681)

• Add NONE or DEFAULT members to most flags types (work by Simon McVittie) (!2576)

• GFile: Add some missing async APIs (work by Marco Trevisan) (!2717)

• Improve internal and process documentation (work by Philipp Withnall) (!2763)

• Add atomic compare-and-exchange APIs returning previous value (work by Marco
  Trevisan) (!2766)

• Add G_DEFINE_ENUM_TYPE and G_DEFINE_ENUM_VALUE macros (work by Emmanuele Bassi)
  (!2788)

• Add platform-independent G_ALWAYS_INLINE and G_NO_INLINE (work by Marco Trevisan)
  (!2781)

• Use waitid() on pidfds rather than a global SIGCHLD handler (work by Philip
  Withnall) (!2408)
