[Android] Fix ant build?
update zlib to v1.2.8
update soundtouch to svn revision 173
fix deb-x64 and osx-x64 builds after soundtouch update
replace alloca with malloc to fix windows builds
forgot to add free() to the previous malloc change
added new license header to missed audio source files
DSBCAPS_GLOBALFOCUS allows sound to still play when the application is in the background. Other backends do this, so why not let dsound do it too.
fixed uninitialzed audio_size variable in WaveFileWriter
Merge branch 'audio_misc'

- audio no longer stops playing when dolphin is in the background with the dsound backend
- wav audio dumps now have the correct sizes instead of an arbitrarily large size
[Android] Add an about screen that shows build revision.
Merge branch 'master' into Texture_2D
