Cross compilation fixes for the stargates, 'gmake client' should now
build, link, and install properly.  Haven't really tried to run stuff though.

	* GNUmakerules: Add target for stripping executables, used instead
	of "install -s" since that doesn't work for cross-compiling.

	* Makeconf.in: Add ELVIN_CONFIG variable that refers to
	'elvin-config'.

	* configure, configure.in: Detect and save the elvin-config path
	since we need a different one for cross-compiling.

	* event/lib/GNUmakefile.in, event/link-agent/GNUmakefile.in,
	event/linktest/GNUmakefile.in, event/program-agent/GNUmakefile.in,
	event/proxy/GNUmakefile.in, event/tbgen/GNUmakefile.in,
	event/trafgen/GNUmakefile.in, os/dijkstra/GNUmakefile.in,
	os/syncd/GNUmakefile.in, sensors/slothd/GNUmakefile.in,
	tmcd/GNUmakefile.in, tmcd/linux/GNUmakefile.in: Cross compilation
	fixes, don't statically link on arm, create "foo-debug"
	executables with debugging info and install separately stripped
	ones instead of passing "-s" to install.

A bunch of engineering on the robot code.  I'm sure I've broken something,
but the majority of it is done and I wanted to get a checkpoint in.

	* GNUmakerules: Add rpcgen rules.

	* Makeconf.in: Add PATH and host_cpu variables so
	cross-compilation works properly.  Add JAVAC and JAR for java
	compilation.  Add BRAINSTEM_DIR that refers to a brainstem build
	directory to be used for the robot build.

	* configure, configure.in: Prepend the arm cross-compile dir to
	PATH.  Detect java for building applets.  Add --with-brainstem to
	specify the brainstem build dir.  Add --enable-mezzanine to turn
	on the mezzanine build.

	* robots/GNUmakefile.in: Add client target that builds the
	subdirs.

	* robots/emc/GNUmakefile.in, robots/emc/emcd.h, robots/emc/emcd.c,
	test_emcd.sh.in, robots/rmcd/GNUmakefile.in, robots/rmcd/rmcd.c,

	robots/vmcd/test_vmcd3.sh, robots/vmcd/test_vmcd4.sh,
	robots/vmcd/vmc-client.c, robots/vmcd/vmcd.c: Updates for the mtp
	switch to using rpcgen.

	* robots/emc/test_emcd.config: Restore missing config line.

	* robots/mtp/GNUmakefile.in, robots/mtp/global_bound.java,
	robots/mtp/mtp.h, robots/mtp/mtp.c, robots/mtp/mtp.java,
	robots/mtp/mtp.x, robots/mtp/mtp_command_goto.java,
	robots/mtp/mtp_command_stop.java, robots/mtp/mtp_config_rmc.java,

	robots/mtp/mtp_update_position.java, robots/mtp/robot_config.java,
	robots/mtp/robot_position.java, robots/mtp/test_mtp.sh: Replace
	hand-generated stubs with xdr stubs for C and java.  Java stubs
	were generated by "remotetea's" jrpcgen.

	* robots/primotion/GNUmakefile.in,
	robots/primotion/buttonManager.hh,
	robots/primotion/buttonManager.cc, robots/primotion/dashboard.hh,
	robots/primotion/dashboard.cc, robots/primotion/flash-user-led.cc,

	robots/primotion/watch-user-button.cc,
	robots/primotion/wheelManager.hh,
	robots/primotion/wheelManager.cc: Replace gorobot with
	garcia-pilot, a beefed up daemon for controlling the robots.
	Improvements include: making use of the user LED and button to
	give some feedback and let the wrangler run a test sequence,
	reboot, and shutdown the robot; Logging of the battery level, how
	often the robot has moved and for how long, and the distance
	traveled; telemetry is sent back to emulab clients; movements are
	now just pivot-move instead of pivot-move-pivot, since the second
	pivot ends up being extra work most of the time; the robot will
	move backwards to cut down on the amount of rotation; and just
	generic cleanups to the code.

	* robots/primotion/garcia.config: The configuration file currently
	used on the garcias.

	* www/GNUmakefile.in: Add garcia-telemetry subdir to the build.

	* www/dbdefs.php3.in: Add TBNodeClass and TBNodeStatus functions.

	* www/garcia-telemetry/Base64.java,
	www/garcia-telemetry/GNUmakefile.in,
	www/garcia-telemetry/GarciaTelemetry.java,
	www/garcia-telemetry/UpdateThread.java,
	www/garcia-telemetry/main.xml: A telemetry applet for the garcia,
	it displays readouts for the various sensors and other bits of data
	gathered by the garcia-pilot daemon.  Hopefully, it will make a
	handy debugging tool.

	* www/garcia-telemetry.jar, www/mtp.jar, www/oncrpc.jar,
	www/thinlet.jar: Java jars used by the robot telemetry applet.

	* www/servicepipe.php3: A slightly enhanced version of
	ledpipe.php3 that can be used for other services, like robot
	telemetry.

	* www/shownode.php3: Add "Show Telemetry" menu item to robot
	nodes.

	* www/telemetry.php3: Telemetry page for the garcia-telemetry
	applet.

More bug fixes for vmcd and friends:

	* GNUmakerules: Set SRCDIR as an environment variable so every
	test doesn't have to be a template.

	* robots/emc/emcd.c: Correctly handle a vision position that is
	dead-on the initial position.  XXX Turn off orientation matching
	for now, it is too strict at the moment so that it favors close
	orientation over close position.

	* robots/mtp/mtp.c: Fix some broken printfs in mtp_print_packet.

	* robots/vmcd/GNUmakefile.in: Add another test.

	* robots/vmcd/test_emcd2.config, robots/vmcd/test_vmcd2.pos,
	robots/vmcd/etst_vmcd2.sh: A test that matches the initial
	positions of two robots.

	* robots/vmcd/test_vmcd.pos: Reduce the distance the robot moved
	between frames.

	* robots/vmcd/vmcd.c: Fix a bugfix and some formatting changes.

Cleanup rmcd a bit:

	* GNUmakerules: Quick fix to the "check" target.

	* robots/rmcd/rmcd.c, robots/rmcd/test_rmcd.sh.in: Cleanup the
	code a bit, add some comments, etc...

Frame out vmcd:

	* GNUmakerules: Fix "check" target so it runs more than one test.

	* robots/emc/emcd.c: Send the vmc config packet out when vmcd
	connects.

	* robots/vmcd/GNUmakefile.in: Add vmcd-related stuff.

	* robots/vmcd/test_emcd.config: Emc config for the test case.

	* robots/vmcd/test_vmcd.sh.in: Simple test case for vmcd.

	* robots/vmcd/vmcd.c: Initial framing of vmcd, just receives and
	dumps packets, actual logic still needs to be put in.

Made a pass over the mtp directory:

	* GNUmakerules: Add a "check" target that runs the executables
	listed in the "TESTS" variable.

	* robots/GNUmakefile.in: Add "mtp" to the list of SUBDIRS.

	* robots/mtp/GNUmakefile.in: Testbed-friendly makefile.

	* robots/mtp/mtp.h, robots/mtp.c: Tweaks and bug fixes.

	* robots/mtp/mtp_test.c: Test case for mtp stuff.

fixe's the config.status bug.

correctly.

Almost there ...

the testbed list.

script runs out of nalloc and nfree and figures out what project (group)
a node is in. It does an ssh over to plastic to run the other script
that does the actual work.

Add a top level rules file with common stuff like install rules.
Beef up tbsetup makefile, and include above files. Add install of all
the tbsetup programs to the bin dir and to the bogus lib/tbsetup
directory.
