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.
