7c0e68a33e Store the filter history in local variables
Despite being marked as restrict (and const for src) to mark the pointers as
being non-aliased, it seems the compiler optimizes better this way.

f65e83c349 Avoid using pa_stream_begin_write with PulseAudio
It seems to actually have a negative performance impact when the system is
under load. Without having actual measurements for any potential benefits,
simply go with the recommended (and previous fallback) method of allocating
space for the write and passing the free method.

Ideally some kind of ring buffer could be used, so rather than constantly
allocating and freeing blocks of memory, it uses the same memory over again
with the callback marking each one as reusable. Unfortunately the callback
isn't given much information to work with, and the update size (minreq) can
potentially change during playback, which complicates things.

179e1c4dbc Don't check for space in the ringbuffer before trying to write

03274a5b95 Ensure at least the specified ringbuffer size is writable
Previously, all but one of the specified size could be written (so for a size
of n, only n-1 was guaranteed writable). All users pretty much compensated for
this, but it makes more sense to fix it at the source.
