This adds two new control channel requests, START_PERFSTAT and STOP_PERFSTAT, that begin and end performance statistics collection respectively. START_PERFSTAT takes the name of the mountpoint on which to enable statistics collection and returns the current monotonic time. STOP_PERFSTAT takes the name of the mountpoint on which to disable statistics collection and returns the current monotonic time and the message timings that have been collected. Performance statistics are collected in a linked list of blocks. pthread locks are used for synchronization. Signed-off-by: David Sheets <dsheets@docker.com>
