5736bbc3e4 Add a source property to skip channel virtualization for multi-channel buffers 
With virtualization disabled, channels are mapped directly from input to output
and any input channel that is missing an output is dropped. Any virtualization
effects (such as HRTF filters) for positional cues are also skipped.

The idea is to allow applications a way to play pre-filtered audio that channel
vitualization effects could interfere with.

ac9a6e891f Fix the cross-compile toolchain script 
CMAKE_INSTALL_PREFIX is now properly set, and the pkgconfig env vars are set so
it won't find .pc files for the default compiler.

7d73ac4405 Avoid calling some AL functions from under the context lock 
There are still some more occurances to clear out (deletion in gen error,
effects, some filters), which shall be coming up. There is a possibility for a
deadlock between the listlock and the global/context lock, if another attempt
to get the listlock is made while under the context lock.

62036745f3 Separate config init from library init 
OSX has a bug where the file descriptor resource limit can't be increased once
certain functions (such as fopen) are used. Since lib initialization happens in
a global constructor and includes opening and parsing config files, it prevents
apps from being able to increase the rlimit once the lib is loaded, which is
usually before main().

By delaying config init, it allows apps the opportunity to change the rlimit
before calling certain OpenAL functions.
