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.

Previously trash directory was being created as part of volume
start operation. And also the user/admin could not delete this
directory from volume even if it is not needed. This patch will
fix the same. From now onwards creation and enforcement on trash
directory will come into pictrure only when trash translator is
enabled. Similarly exact same behaviour is reflected on internal-op
directory inside trash directory.

In the notify function in trash xlator, a lookup is performed
to obtain path of old trash directory. The result usually contains
path without '/' at the end. The trash xlator maintains expects
'/' at the end for the values such as 'old trash dir' and
'new trash dir'. Otherwise certian checks in the code will fail.
