Linux xargs calls the command with no arguments if it gets no inputs, which
`docker rmi` complains about. It provides -r / --no-run-if-empty to prevent
this but unfortunately this isn't supported on OSX.
Ignore errors from `docker rmi` so that `make clean` will keep going and clean
up later stuff.

Add a mount suitability predicate, a pong reply message type, and a log
notice message type. Also, fixes the multi-line mount point printing issue.

Mount points are now made dynamically if either the leaf doesn't exist
or the leaf has no children. Any proper prefix of the target mount point may
or may not exist prior to mounting.

During start-up, logs are sent to syslog and stderr and the console if
syslog is not available. -l logfile will also send the logs to logfile but
only prior to any log trigger events. -m mount_trigger lets the user
specify the mount point to watch for to begin sending logs to
-t triggered_log file which may be on the newly mounted file system. Log
concatenation and rollover are not implemented, yet. Logging functionality
has been separated into transfused_log.c. Locks have been placed around
shared fds. The writer thread is now symmetric to the reader thread instead
of inheriting the parent's thread in order to trigger log switchover after
the file system proxy has started. The coredump size rlimit has been lifted.

The event string in the 9p socket file system now contains a 1 byte
channel type immediately preceding the connection ID. This channel type
determines which protocol will be used on the channel -- m for FUSE
protocol, e for events. The event messages are host-initiated and have
the following structure:
2 bytes for total length
2 bytes for path length + NUL (x)
x bytes for path
1 byte for syscall
stderr logging was also changed to syslog-based logging in this patch.
