os2: SDL_DestroyMutex should ignore NULL mutexes.
Every other backend does this, so this should match, now.
It's possible this was harmless, but we can avoid the system call
and the (likely?) debug message when it fails, though!

Export SDL_LinuxSetThreadPriorityAndPolicy() function (#4877)
It's marked as being a public symbol internally, however, it was missing from the header files and not visible in the shared library.  This adds it to the necessary headers and to the DynAPI list to expose it for use by applications.

Cameron Gutman 5dccffd7e4 Allow usage of the new Condition Variable code with Critical Sections
Vista and later provide the SleepConditionVariableCS() function for this.

Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to
SDL_syscond_cv.c which better reflects the implementation of condition
variables rather than the implementation of mutexes.

Fixes #4051.

Ozkan Sezer 77c8d11137 configuration updates for dlopen:
- cmake, configure (CheckDLOPEN): --enable-sdl-dlopen is now history..
  detach the dl api discovery from SDL_LOADSO_DLOPEN functionality.
  define HAVE_DLOPEN. also define DYNAPI_NEEDS_DLOPEN (CheckDLOPEN is
  called only for relevant platforms.)
- update SDL_config.in and SDL_config.cmake accordingly.
- SDL_dynapi.h: set SDL_DYNAMIC_API to 0 if DYNAPI_NEEDS_DLOPEN is
  defined, but HAVE_DLOPEN is not.
- pthread/SDL_systhread.c: conditionalize dl api use to HAVE_DLOPEN
- SDL_x11opengl.c, SDL_DirectFB_opengl.c, SDL_naclopengles.c: rely
  on HAVE_DLOPEN, not SDL_LOADSO_DLOPEN.
- SDL_config_android.h, SDL_config_iphoneos.h, SDL_config_macosx.h,
  SDL_config_pandora.h, and SDL_config_wiz.h: define HAVE_DLOPEN.

Closes: https://github.com/libsdl-org/SDL/pull/4351

Cameron Gutman f70e197363 Fix waiting on condition variables with the SRW lock implmentation
When SleepConditionVariableSRW() releases the SRW lock internally, it causes
our SDL_mutex_srw state to become inconsistent. The lock is unowned yet inside,
the owner is still the sleeping thread and more importantly the owner count is
still 1.

The next time someone acquires the lock, they will bump the owner count from 1
to 2. At that point, the lock is hosed. From the internal lock state, it looks
to us like that owner has acquired the lock recursively, even though they have
not. When they call SDL_UnlockMutex(), it will see the owner count > 0 and not
call ReleaseSRWLockExclusive().

Now when someone calls SDL_CondSignal(), SleepConditionVariableSRW() will start
the wakeup process by attempting to re-acquire the SRW lock. This will deadlock
because the lock was never released after the other thread had used it. The
thread waiting on the condition variable will never be able to wake up, even if
the SDL_CondWaitTimeout() function is used and the timeout expires.

SDL_systhread.c and SDL_syslocale.c used to call LoadLibrary() without
calling FreeLibrary() later.  GetModuleHandleW() should always succeed
because GetModuleHandleW() itself is imported from kernel32.dll and we
don't need to bother releasing it.

Sam Lantinga 0500c04468 Fix SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL also applying to HIGH priorities
As the name suggests, the hint should only apply to SDL_THREAD_PRIORITY_TIME_CRITICAL

The resulting priorities for my current distro result in these values:

     | High         | Time Critical
Hint |--------------|-----------------
 0   |  P=10 N=-10  | P=5   N=-15
 1   |  P=10 N=-10  | P=-21 N=0

Sam Lantinga 07eae7d670 Fix process randomly getting killed when SDL_THREAD_PRIORITY_HIGH/TIME_CRITICAL is set
When we request realtime priority from rtkit, we have a rttime limit. If we exceed
that limit, the kernel will send SIGKILL to the process to terminate it.

This isn't something that most high priority processes will want, only processes
that selectively opt into SCHED_RR/FIFO through SDL_HINT_THREAD_PRIORITY_POLICY
should be subject to this level of scrutiny.

This change:
  * Switches non-apple posix OSs to use SCHED_OTHER instead of SCHED_RR
for SDL_THREAD_PRIORITY_HIGH/SDL_THREAD_PRIORITY_TIME_CRITICAL.
  * Fixes using a hardcoded RLIMIT_RTTIME, instead queries it from rtkit
  * Only sets RLIMIT_RTTIME for MakeRealtime rtkit requests
  * Adds a note regarding the possible SIGKILL with SDL_HINT_THREAD_PRIORITY_POLICY
  * Introduces SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL to allow apps to acquire realtime scheduling policies on Linux
