0badb4059f Restructured audio providing a bit. If a provider cannot provide 16-bit mono audio with a sample rate higher than 32kHz, an intermediate converting provider will be inserted to fix it. Made the lavc audio provider rely on this for downmixing instead of doing it with libavcodec (used to fail on audio with >2 channels). 
Originally committed to SVN as r2265.

6bec0322e4 split out the downmixing audio provider into its own .h/.cpp, in preparation for using it in the ffmpeg audio provider.

923b347356 Some more checking in PCM provider. Had apparently missed a way EnsureRangeAceesibleble() could fail. This means of failure should no longer be possible.

d01b4ec3e9 Yet some more sanity/error checking, although it should never be triggered.

2c7da25e91 Avoid strncmp() for checking fourCC codes and use a handcrafted function for it instead. Also add some assertions for null pointer checks.

d1b8355ff2 Rename endian.h to aegisub_endian.h to avoid clash with system headers on some systems.

a7b64fe694 Make PCM WAV reading (almost) machine endian neutral. The actual sample data read are still assumed to be in machine endian, which will produce garbage output on big endian archs.

08910b5a9d Make PCM audio provider access the file memory mapped instead of through regular file access, per bug #686. Tested to work on Windows. 
I've also added a POSIX implementation but it's untested and might not even build.
The implementation is not actually thread safe, but this shouldn't be a problem in most cases, yet. It should still be fixed at some point.

89d076c760 Apparently long long isn't safe, trying with int64_t instead then...

8909ea48e2 Replace all (applicable) instances of __int64 with long long. (All except those in foreign header files.)

044f104a2e Forgot to remove some debugging messages from the PCM audio provider, making using any other audio provider really annoying.

128dd0df0f What a fix, #113 (direct PCM WAV reading) now quite much implemented and working.

93f6ef6d7a Issue #113 - reading PCM audio directly from disk. Almost works, but downsampling from non-mono to mono seems to be broken. 
Originally committed to SVN as r1528.
