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.

+# I've cleaned this up as much as I can - making sure the gdstates directory
+# gets cleaned up, checking whether the CLI command actually succeeded before
+# parsing its output, etc. - but it still fails in Jenkins. Specifically, the
+# first get-state request that hits the server (i.e. doesn't bail out with a
+# parse error first) succeeds, but any others time out. They don't even get as
+# far as the glusterd log message that says we received a get-state request.
+# There doesn't seem to be a core file, so glusterd doesn't seem to have
+# crashed, but it's not responding either. Even worse, the problem seems to be
+# environment-dependent; Jenkins is the only place I've seen it, and that's
+# just about the worst environment ever for debugging anything.
+#
+# I'm marking this test bad so progress can be made elsewhere. If anybody else
+# thinks this functionality is important, and wants to make it debuggable, good
+# luck to you.
