pulsecore: Cache daemon shm size inside pa_core

Browse source 
The daemon `shm-size-bytes' configuration value was read, and then
directly used, for creating the initial server-wide SHM files.

This is fine for now, but soon, such server-wide SHMs will be replaced
with per-client SHM files that will be dynamically created and deleted
according to clients open and close. Thus, appropriately cache this
configuration value.
