f14cf8289e Add a method to update device-dependant effect parameters.

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

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

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
