core: run many bricks within one glusterfsd process

2017-02-02T00:54:58+00:00

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.
