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.
