This works by using semi-documented[1] exception to tell the debugger
that a thread needs to have its name changed.
If this exception is not caught and handled by something, it will crash
the process, so we need to set up our own handler in case there's no
debugger attached or the debugger can't handle this type of exception.
Since SEH is not supported by gcc on i686 (at the moment), we need to use VEH
instead. For completeness the MSVC-oriented code still uses SEH, although
there is no reason why it shouldn't work with the VEH variant used by MinGW.
VEH handler has to be set up somewhere (g_thread_win32_init () works nicely)
and removed once it's not needed (g_thread_win32_process_detach () is added
expressly for that purpose). Note that g_thread_win32_process_detach() is
only called when glib is unloaded by FreeLibrary(), not when glib-using
process is terminating.
This exception is known to work with WinDbg, and adding support for it into
GDB proved to be feasible (GDB patch will be sent upstream, eventually).

GLib has a pervasive assumption that function and data pointers are
basically interchangeable, which is true in all modern ABIs,
but not actually guaranteed by ISO C. If someone tries to use GLib on a
platform where function and data pointers are different sizes, fail early.

Currently g_mem_gc_friendly is declared in both gmem.h and glib-init.h
files, we will have reports on each unit that include these two files.
This patch removes the redundant declaration from glib-init.h
Since g_mem_gc_friendly is related to gmem.h and was first declared in
this header which also exports it via glib.h, then declare it in gmem.h
Other files already include gmem.h: garray.c and gslice.c, no need to
change anything.

Any flags specified as well as "all" are subtracted from the result,
allowing the user to specify FOO_DEBUG="all,bar,baz" to mean "give me
debugging information for everything except bar and baz".

Instead of running the GPrivate destructors from our thread proxy code,
run it from the DllMain handler for the DLL_THREAD_DETACH case.
This should ensure that thread-local data is free at the exit of all
threads -- not just the ones we created for ourselves.
