243939f94f Allow delaying playback start until context creation, and don't use UpdateSize to store the buffer size
This will make it possible to support the context attributes (frequency,
refresh, etc) for some backends

0ac9e57d28 Store the requested mono/stereo source count and sends in the device
Although the properties are set as context attributes, they are queried from
the device. If multiple contexts per device are ever supported, it would not
be straight forward about where to read the values from. This way, the
attributes can be treated as device-specific attributes that are updated when
a new context is created.

f3a3358e63 Fix for MSVC
MSVC won't accept zero-sized arrays at the end of structs, if that struct is
used in another struct that's not also at the end. This wastes a float for each
FILTER object

34ea7eba9e Add preliminary support for the EAX Reverb effect
Not all parameters are supported yet, though it is a little more fuctional than
standard reverb

7a7a4844f4 Make the filter history buffer size flexible
This lets the filter history buffer be as big as needed for a given use, so
that it can have a size large enough for the more demanding cases, but not be
wasteful for lesser-demanding cases, while not incuring the overhead of an
added pointer indirection

778b74cae1 Reimplement panning using lookup tables, based on a patch by Christian Borss
This allows speaker positions to be specified by discrete angles around the
listener, providing more flexibility and configurability in placement.
Additional patches to take advantage of this are forthcoming.

fc4c867f27 Add initial AL_EXTX_buffer_sub_data support
Note that this is an in-development extension, as noted by the EXTX moniker
instead of EXT. It's behavior is subject to change, and the extension string
will be removed (replaced with the official string once it's finalized).
Developers are discouraged from using this in production code, though feel
free to play around with it.
