pulse-server: increase buffer size

Browse source 
Because we keep everything in a ringbuffer and provide exactly the
required amount of data, we can use 1/4 buffers.
Also increase the buffer size. We don't want to limit the buffer size
to the negotiated tlength because it can be increased later. Instead
scale it to the max quantum size (8192) with a max resample rate of 32.
