Make our windows builds usable from meson.

This creates our pkg-config files on windows as well as fixes an include in
pidgin.h which can cause some issues.

This isn't usable as is, as you need a machine-file and a pkg-config wrapper
to make this all work, but that will be updated in the win32-dev.7z file thats
on data.imfreedom.org.

Testing Done:
Compiled guifications2 (which now uses meson) on windows and verified it works.

@signaldesc

Emitted when a #PurpleStoredImage is about to be destroyed. This allows

for what amounts to weak references. Code can hold onto a pointer to

the PurpleStoredImage without actually "holding" a reference. They can

then use a signal handler to let them know when their img is about to

be destroyed.

@param img The image about to be destroyed.

@note It's not possible to purple_imgstore_ref() img to save it.
