This fills in the core pieces and fully implements it for Mac OS X.
Most other platforms, at the moment, will report a disconnected device if
it fails to write audio, but don't notice if the system's device list changed
at all.
64-bit Linux uses a "long" instead of "long long" for 64-bit ints.
Added a special-case this so SDL_PRI?64 doesn't trigger compiler warnings
when used with SDL's 64-bit datatypes on 64-bit Linux.

The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
