core: run many bricks within one glusterfsd process
This patch adds support for multiple brick translator stacks running in
a single brick server process. This reduces our per-brick memory usage
by approximately 3x, and our appetite for TCP ports even more. It also
creates potential to avoid process/thread thrashing, and to improve QoS
by scheduling more carefully across the bricks, but realizing that
potential will require further work.
Multiplexing is controlled by the "cluster.brick-multiplex" global
option. By default it's off, and bricks are started in separate
processes as before. If multiplexing is enabled, then *compatible*
bricks (mostly those with the same transport options) will be started in
the same process.
