Implemented thread priority as the 'nice' value on Linux. High priority threads require root permissions (you shouldn't give your game root permissions though!)

Fix segfault in ALSA_OpenDevice()
When alsa is linked to libsdl instead of being loaded on demand at runtime the
alsa macro snd_pcm_hw_params_alloca(ptr); misbehaves.
That macro calls snd_pcm_hw_params_sizeof() in order to determine the amount of
memory to allocate but due to mis-placed define that function is replaced with
ALSA_snd_pcm_hw_params_sizeof by preprocessor (and in case of link to alsa that
function pointer is initialized to itself).
Attached patch fixes the issue.
The following patch fixes some of the bitrot for the Nintendo DS port.
The support is still basic at the moment, but it allows to run the "general"
test under the current head of tree (parent: 5269:11bd1585efb5 tip).
Most of the patch is mine, but I integrated a couple changes that John
Magnotti posted on Feb 1st.
I think this also fixes the bug relating to non-latin characters in filenames, since UNICODE wasn't defined in SDL_rwops.c

SDL based applications sometimes display the wrong application name in the
Sound Preferences dialog when using pulseaudio.
I can see from the code that the SDL pulse module is initiating a new pulse
audio context and passing an application name using the function
get_progname().
The get_progname() function returns the name of the current process. However,
the process name is often not a suitable name to use. For example, the OpenShot
video editor is a python application, and so "python" is displayed in the Sound
Preferences window (see Bug #596504), when it should be displaying "OpenShot".
PulseAudio allows applications to specify the application name, either at the
time the context is created (as SDL does currently), or by special environment
variables (see http://www.pulseaudio.org/wiki/ApplicationProperties). If no
name is specified, then pulseaudio will determine the name based on the
process.
If you specify the application name when initiating the pulseaudio context,
then that will override any application name specified using an environment
variable.
As libsdl is a library, I believe the solution is for libsdl to not specify any
application name when initiating a pulseaudio context, which will enable
applications to specify the application name using environment variables. In
the case that the applications do not specify anything, pulseaudio will fall
back to using the process name anyway.
The attached patch removes the get_progname() function and passes NULL as the
application name when creating the pulseaudio context, which fixes the issue.
* Formalized the interface with Java methods in SDL_android.h
* We don't need the feature system, at least right now
* Fixed waiting for the SDLMain thread
- Added 'feature' enable/disable so we're not running accel/sound/whatever in Java when we don't need to be
- More work on the sound system. But it still crashes pretty horribly, not sure why yet.

Hi:
Here are some small fixes for compiling SDL against mingw-w64.
(see http://mingw-w64.sourceforge.net/ . Despite the name, it
supports both win32 and win64.)
src/audio/windx5/directx.h and src/video/windx5/directx.h (both
SDL-1.2 and SDL-1.3.) I get compilation errors about some union
not having a member named u1 and alike, because of other system
headers being included before this one and them already defining
DUMMYUNIONNAME and stuff. This header probably assumes that those
stuff are defined in windef.h, but mingw-w64 headers define them
in _mingw.h. Easily fixed by moving NONAMELESSUNION definition to
the top of the file.
src/thread/win32/SDL_systhread.c (both SDL-1.2 and SDL-1.3.) :
The __GNUC__ case for pfnSDL_CurrentBeginThread is 32-bit centric
because _beginthreadex returns uintptr_t, not unsigned long which
is 32 bits in win64. Changing the return type to uintptr_t fixes
it.
video/SDL_blit.h (and configure.in) (SDL-1.3-only) : MinGW-w64
uses msvcrt version of _aligned_malloc and _aligned_free and
they are defined in intrin.h (similar to VC). Adding proper
ifdefs fixes it. (Notes about macros to check: __MINGW32__ is
defined for both mingw.org and for mingw-w64 for both win32 and
win64, __MINGW64__ is only defined for _WIN64, so __MINGW64__
can't be used to detect mingw-w64: including _mingw.h and then
checking for __MINGW64_VERSION_MAJOR does the trick.)
SDL_win32video.h (SDL-1.3-only) : Tweaked the VINWER definition
and location in order to avoid multiple redefinition warnings.
Hope these are useful. Thanks.
It was causing problems, and it really doesn't make sense to do it that way.
Fixes Bugzilla #834.

I think that's how it works.

I'm not confident this is a complete fix, but I'm not confident the current
resamplers are really worth keeping at all, either.

The thread ID is an unsigned long so it can hold pthread_t so people can do naughty things with it.
I'm going to be adding additional useful thread API functions, but this should prevent crashes in people's existing code on 64-bit architectures.

Added a FIXME for Ryan to look at, too. :)
