Previously, with JACK installed, the configure script would enable the
JACK indev; this broke on OS X due to an incomplete pthreads
implementation. Add some simple macros to map libdispatch to pthreads
on OS X.

This fixes building on older mingw (both mingw.org and mingw64;
mingw64 from before May 2011).

When SSE2 or higher compiler optimizations are used, mingw uses
the _mm_mfence intrinsic for MemoryBarrier, however it doesn't include
the appropriate headers automatically.

The versioning facility in the Solaris linker differs from Linux in 3 ways:
1. It does not support globs in linker scripts for
symbol versioning -- this is a GNU extension.
2. The linker argument is '-M', instead of '--version-script'.
3. It is picky about line endings.
Each symbol or directive must be on a line of it's own.
Let's use make_sunver.pl from GCC to generate a version script that works
correctly with the Solaris linker. It's function is to correctly expand the
globs in the original generated version script.

This removes the requirement of calling w32thread_init before being
able to use the threading primitives.

The emulation uses native InitOnce* APIs on Windows Vista+, and a
lock-free/allocation-free approach using atomics and spinning for
Windows XP.

Wrap the function calls in a similar fashion to how it's being done

This avoids annoying warnings about unused functions. The compatibility
wrapper is designed to provide a complete (stub) API, so some functions
being unused by some files is natural and no reason for a warning.

When explicitly targeting Vista or newer (which only happens if the
caller explicitly sets _WIN32_WINNT to a high enough value via the
extra cflags option - otherwise configure script sets
-D_WIN32_WINNT=0x0502), we already unconditionally link to the
ConditionVariable functions, since 4622f11f9.
Similarly use the newer -Ex versions of CreateEvent, CreateSemaphore,
InitializeCriticalSection and WaitForSingleObject, that all appeared
in Vista. When building Windows Store applications, the older versions
of these functions aren't available, only the -Ex functions. When
doing such a build, the user can set -D_WIN32_WINNT=0x0600 to
forcibly use the newer functions instead.

The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
[....]
}

The macros forbidding the system functions no longer exist, obviating
the need for the #undefs.

This reverts commit 4622f11f9c83db8a2e08408c71ff901826ca652c.
The compiler should be able to do the dead code elimination now
without this when the cond_* names point directly to the real
functions instead of to local function pointers.

This reduces the call overhead slightly. More noticeably, it
restores the earlier (unintended?) feature that condition variable
functions work just fine even if w32thread_init() hasn't been called.
This was broken as a side effect of 4622f11f9, if explicitly targeting
Vista+.
This makes w32threading work in VP8 again, if targeting Vista+.

The emulation code is not needed when targetting Vista+
This helps getting rid of CreateSemaphore symbol, which is
forbidden in Windows Store apps.

This adds support for building on Plan 9 x86-32. The compat/plan9
directory contains these items:
- replacements for the 'head' and 'printf' shell commands
- wrapper for main() to disable FPU exceptions
Larger required changes to the system are described in the
documentation.
