Avoid holding the context lock while setting source parameters

Note that some parameters still need the lock when getting or setting them.

Don't defer stopped and initial source state changes
...
Typically when these are set, an app will be releasing the buffer from the
source, possibly to immediately reuse it. There would be an extra burden placed
on the app if it was required to process updates before it could fully release
the buffer from the source.

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.

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.

Add an HRTF filter for mono sources
...
The data is based on the KEMAR HRTF data provided by MIT, which can be found at
<http://sound.media.mit.edu/resources/KEMAR.html >. The compact measurements
were used. See hrtf_tables.inc for more information.
The filter is only available for stereo output, using a 44100hz playback rate.
Note also that it currently only applies to mono sounds, and the cf_level and
head_dampen config options are ignored while it is active.
