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.

Use Index heal instead of full heal to heal files because if both bricks are on
the same node, the 2 full heal threads might compete and fail to acquire the non
blocking locks and the file might not get healed during the full heal crawl.

Currently data-self-heal.t creates files directly on the brick and sets
the trusted.gfid xattr. Later it depends on stat from mount to create
the .glusterfs/<gfid hard link>. The link creation doesn't seem to be
happening always. Hence changing the test to create files from the mount
point before modifying afr xattrs in the backend and triggering heal.
Also disabled all performance translators. With these changes,
http://review.gluster.org/#/c/10667/ is not failing in data-self-heal.t
