run/depot_autopilot: less interactive mode

Browse Source 
In less interactive mode, the run script doesn't give up on missing test
archives but instead removes the corresponding tests and marks them "missing".
This mode avoids total failure of a platform in automated test infrastructures
when only a few archives are missing.

Fixes #3120

There are two additional features that are rather intended for automated test
infrastructures. One is the determination of the number of missing tests and
the other is the less interactive mode. The number of missing tests is the
number of tests that should have been executed on a platform (not skipped) but
for which the run script couldn't manage to produce a result. This can happen
if the hardware runs into unrecoverable problems during testing or if the
script is called with the less interactive mode (as explained later in more
detail).
As an example let's say we have 72 tests in total and 8 of them get skipped
because of incompatibility with the current platform. Then, the number of
executed tests is 64. Let's assume the run script finishes with 35 tests
succeeded and 19 tests failed, the number of missing tests is consequently 64 -
35 - 19 = 10. This calculation can be done automated by summing up the values
'succeeded' and 'failed' from the results overview and subtracting it from the
value given in the line "Number of tests to run" that is printed out by the run
script at the very beginning. Missing tests normally indicate problems with the
target platform or the testing infrastructure itself.
Now to the less interactive mode: This is a mode in which the run script
doesn't give up (as usual) when there are test archives missing in the host
depot. Instead it solves the conflict by removing the affected test packages or
test sources. If a test package gets removed this way, the corresponding test
is neither executed nor considered in the result overview (unlike skipped
tests). Thus, it is a missing test and can be detected as described above. You
can determine whether a missing test is missing due to unmet archive
dependencies by inspecting the serial ouput of the run script. For each
incomplete package or source archive of a test, the run script yields a
warning:
! Warning: remove test [package|source] of "<TEST_NAME>" because of missing
archives
The less interactive mode can be activated by appending " --autopilot " to the
'RUN_OPT' variable in your '<BUILD_DIR>/etc/build.conf' file.
