Subject: [PATCH 7/7] [WIP] Initial LAVA support

Linaro Automated Validation Architecture (LAVA) launches a test suite
on the target but thereafter only observes stdout.

LAVA knows that a test case has started or ended based on signals
emitted to stdout:
(setup)
<LAVA_SIGNAL_STARTTC test_case_name>
(teardown)
<LAVA_SIGNAL_ENDTC test_case_name>
<LAVA_SIGNAL_TESTCASE TEST_CASE_ID=test_case_name RESULT=pass|fail \
  [[ MEASUREMENT=numeric_measurement ][ UNITS=units_string]]>

It is valid to have a measurement without units, but not units without a measurement.
