88de4e15b3 Mark the source for updating when setting a buffer on it 
Changing the buffer can change the playback format, which can require different
source parameter calculations. Queueing a buffer on a source that has no
buffers (or only buffers without a format, eg. buffer 0) has the same effect

6d1d61026d Be context-agnostic in the effect Create functions 
This allows the effect Update functions to handle the playback frequency being
changed. By default the effects assume a maximum frequency of 192khz, however,
it can go higher at the cost of the sample buffers being cleared and the risk
of an abort() if reallocation fails

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.

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

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.

a75e75aef5 Implement an alternative low-pass filter 
This method samples from the buffer so that it gets a time-correct 5khz stream,
which is subtracted from the original sample and has the high-frequency gain
applied, then added back.
A better method may be to average all the samples from the current one to the
one freq/5000 away, instead of bilinear filtering the two nearest freq/5000
apart. Processing cost will need to determine its viability

4caf2c7edd Implement AL_EFFECT_REVERB 
Here is a quick description of how the reverb effect works:

 +--->---+*(4)
 |       V       new sample
 +-----+---+---+    |
 |extra|ltr|ref| <- +*(1)
 +-----+---+---+
   (3,5)*|   |*(2)
         +-->|
             V
         out sample

 1) Apply master reverb gain to incoming sample and place it at the head of the
    buffer. The master reverb gainhf was already applied when the source was
    initially mixed.
 2) Copy the delayed reflection sample to an output sample and apply the
    reflection gain.
 3) Apply the late reverb gain to the late reverb sample
 4) Copy the end of the buffer, applying a decay gain and the decay hf ratio,
    and add to the late reverb.
 5) Copy the late reverb sample, adding to the output sample.

 Then the head and sampling points are shifted forward, and done again for each
 new sample. The extra buffer length is determined by the Reverb Density
 property. A value of 0 gives a length of 0.1 seconds (long, with fairly
 distinct echos) , and 1 gives 0.075 seconds (short, indistinct echos).
 The decay gain is calculated such that after a number of loops to satisfy the
 Decay Time, a sample will be 1/32768th as powerful (virtually insignificant to
 the resulting output, and only getting further reduced). It is calculated as:

 DecayGain = pow(1.0f/32768.0f, 1.0/(DecayTime/ExtraLength));

 Things to note: Reverb Diffusion is not currently handled, nor is Decay HF
 Limit. Decay HF Ratios above 1 probably give incorrect results. Also, this
 method likely sucks, but it's the best I can come up with before release. :)
