Relatively simplistic implementations of ResumeThread (stub) and
SignalObjectAndWait (bAlertable is ignored). Both are needed for ProRes 4:2:2
support on Linux.

Implement Win32 mutexes; they used to just be mapped on top of events, which
is not the same thing at all.
The implementation is pretty much the obvious one, similar to the
current critical section implementation and the semaphore implementation;
a single lock count protected by a pthread mutex, and an event lockers can
sleep on to know when the mutex is available.
Also make CreateMutexA and ReleaseMutex available even if QuickTime codecs
support is not configured.

Two simple bugfixes for semaphores in WaitForSingleObject:
First, semaphore count should be decreased on loading the semaphore, not
increased. The case for duration=0 had this wrong (duration=-1 was fine).
Second, the code for duration=-1 forgot to set the return value, so it
would always return WAIT_FAILED.

loader/win32.c contains a global linked list of all existing mutexes
(whose head is called mlist), which is accessed from multiple threads,
and as such needs to be protected by a mutex. Fixed.
Same thing for the global linked list of all existing threads, whose
head is called list.

Some codecs, and more recently Microsoft's CRT library, expect GetModuleHandle(NULL)
to return a pointer to the program's PE header mapped in memory. Thus, just returning
0x0 or 0x1 won't do it anymore, so create a minimal PE header and return that.
Patch originally by Gianluigi Tiesi ( mplayer (at) netfarm (dot) it ).

Some extra changes snuck into my commit; they'll probably be reviewed
and committed to Subversion eventually, but were not part of the fix
for WaitForSingleObject on thread handles.

Some codecs need this for clean shutdown (as opposed to a crash); we don't
really support timed wait since POSIX doesn't, but it doesn't seem necessary.

Earlier, cs->locked was accessed outside the mutex to get around
the problem that default pthread mutexes are not recursive
(ie., you cannot do a double-lock from the same thread), causing
a thread-safety problem, as both detected by Helgrind and showing
up in some multithreaded codecs.
The ideal solution here would be to simply use recursive pthread
mutexes, but there were concerns about reduced debuggability and
possibly portability. Thus, instead, rewrite the critical sections
to be a simple lock count (with owner) protected by a regular mutex.
Whenever a thread wants to enter the critical section and lock_count
is not 0, it sleeps on a special event that tells it when the
critical section is available.

CreatePalette had problems for me, and looking at the code it was quite
obvious why; someone had reversed the order of the two elements of the
LOGPALETTE struct, causing it to allocate and copy a bogus amount of memory.
Why on earth anybody would want to do that is beyond me; whoever did it even
left a comment, but it wasn't very helpful, as it crashed nevertheless. :-)

Events have a “reset” member that specify if they flag is automatically
set back on read/wait. However, this was populated by bManualReset, so the
flag was inverted and once an event was set, it would forever be counted
as so. Fixed by inverting the flag.

These functions return void*, which is compatible with any pointer,
so there is no need for casts.

We were using an inconsistent mix of the three variants and 'volatile' should
be the most correct and portable variant.
