At Tracker we want to mmap files using O_NOATIME. With GMappedFile this is at
the moment impossible. For that reason I added the constructor new_from_fd to
the GMappedFile type.

This reverts commit c7f9cd17d446938aaf4126e0753302676f66fd22.
The old macros in gthread.h used this variable, so it must remain in
place to keep ABI compatibility.
Replace it with g_thread_create_with_stack_size() and a real function
implementation of g_thread_create().
Modify a testcase that was calling g_thread_create_full()
inappropriately (it was using the default values anyway).
This was ignored on Windows. On POSIX, where supported, it controlled
if we ended up with a proper system thread or a user-mode thread. Linux
did not support this.
Switch 'self' 'join' and 'create' from using the vtable to being called
via normal g_system_thread_* internal API (implemented in each of
gthread-{posix,win32}.c).
Again, we can put NULL in the vtable since these were never used from
gthread.h.
Thread priorities were already documented as not working on Solaris, and
they are meaningless on Linux unless the process separately requests
realtime scheduling (and even then, it appears only to work as root).
We can safely put a NULL into the vtable for set_priority since nothing
outside of gthread.c ever calls this (and that call is gone).
The "unknown reason" that the native thread implementation was broken is
because functions in kernel32.dll are (obviously) following Microsoft's
__stdcall ABI, not the GCC ABI.
Change our function pointers to be __stdcall pointers and change our
emulated implementation to match.
A pair of macros to define a constructor function (on compilers that
support such a concept) and to ensure that the function is run exactly
once (on compilers that lack such support).
Presently only GCC is implemented.
We remove the macros while at the same time switching all libglib users
from g_private_new() to g_private_init(). We deal with the strange
expectations of the libglib code that g_private_* should work before the
GPrivate has been initialised with a temporary shim.
- expose the structure types for GLib internal use only
- avoid infinite recursion hazards by ensuring that GPrivate never
calls back into any other part of GLib
- substantially rework the Windows implementation so that it never
holds locks, contains no arbitrary limits and doesn't waste
100*sizeof(void*) per thread
We have to keep the macro hacks for the time being since some code
inside libglib depends on it.
Now that GMutex is exposed we can avoid the dance we did in ./configure
to allocate the correct amount of space for it within the GStaticMutex.
Remove the checks and move the definitions to gthread.h, trying very
hard to keep ABI-stable (even though we will be deprecating this soon).
