Dolphin SVN6244

r6244

• Remove unnecessary shadow variables and signed/unsigned comparisons.

r6243

• Fixed the glitches when an internal resolution other than Native was used in the OpenGL plug-in.

r6242

• Apply u-ra's patch to speed up CriticalSection on systems that use POSIX-threads (that is, not windows).

r6239

• Core/AudioCommon: Feed bigger audio chunks to the output devices in case of underrun. This should eliminate the crackling with alsa and pulseaudio backends and replace it with much nicer pauses. This is only interesting for audio backends that do not respect Mixer::GetNumSamples() and should not impact users able to run the DSPLLE at full speed.
• The cost of this is an added LLE audio latency of about 0.06 s in the continuous
• playback case. If that is too much, lower the low watermark.
