depot_autopilot: provide repeat mode

Browse Source 
Adds an config attribute to the Depot Autopilot component:

:<config repeat>:

  Can be one of

    "false"         - process the given test list only once,
    "until_forever" - endlessly repeat processing the given test list,
    "until_failed"  - repeat processing the given test list until it fails.

Adds an environment variable to the Depot Autopilot Run script:

:TEST_REPEAT:

  Same as the <config repeat> attribute of the Depot Autopilot.

This is useful when having to debug very sporadic errors during one test
or a series of tests.

but rather helps integrating the Autopilot into a Linux-based test
environment. The run script provides the following features:
* The user only lists the desired test packages and selectively defines the
platform compatibility for tests where this is necessary
* The run script executes the Autopilot scenario on the target platform,
repeadedly if necessary, until an overview with all tests can be presented
* Each time the system gets booted, the Autopilot is configured only with
the remaining tests
* Tests that caused the run script to re-boot the target platform are listed
as "failed" with cause "reboot" in the overview
* Exits with 0 if a complete overview can be accomplished and all tests are
either "ok" or "skipped" and otherwise with a value < 0
* Provides a convenient interface for debugging single tests
* Creates a complete Autopilot scenario from a list of local test packages
* Optional platform dependencies can be defined for each test package
* Simple interface for selectively using test ingredients built from source
* Can be combined with a list of source packages and gcov to show test coverage
* Exits with 0 if all tests are either "ok" or "skipped", otherwise with < 0
* The target is re-booted if the scenario gets stuck
* On each re-boot the Autopilot is configured only with the remaining tests
* Tests that caused a re-boot are listed as "failed" with cause "reboot"
* The final Autopilot result overview reflects all results from all boots
* If a complete result overview can't be obtained, a partial one is simulated

Depot Autopilot Run script
~~~~~~~~~~~~~~~~~~~~~~~~~~
By default, the Run script tries to evaluate all tests that are internally
configured, that is, normally, all that are available as package recipes in
the main repositories. This includes one test that is prepared for the later
examination by gcov as well as gcov itself, which is executed like a test at
the end of the test list to examine the above mentioned adapted test. The test
list is processed only once and all test ingredients are used from packages,
assuming the depot user is 'genodelabs'. For this default behavior just call
the script like any "normal" Run script:
! make run/depot_autopilot KERNEL="nova"
However, this is normally a pretty time intensive process and meant for the
integration into automatic test infrastructures rather than manual evaluation.
This is why you might want to adapt the scenario, for instance, for debugging
one or more tests that failed during your automated testing. For this purpose,
a user interface is given through specific environment variables. This is an
example containing all of these variables:
! make run/depot_autopilot \
! > TEST_PKGS="test-libc_vfs test-log" \
! > TEST_SRCS="test-xml_generator test-xml_node" \
! > TEST_BUILDS="server/ram_fs test/libc_vfs" \
! > TEST_MODULES="ram_fs test-libc_vfs vfs.lib.so" \
! > TEST_REPEAT="until_failed" \
! > KERNEL="nova"
:TEST_PKGS:
List of test package-archives that supersedes the internal list if set.
:TEST_SRCS:
List of test source-archives that supersedes the internal list if set.
:TEST_BUILDS:
List of test build-targets that be build from the local repositories.
:TEST_MODULES:
List of test boot-modules that overlay the contents of the package-archives.
:TEST_REPEAT:
See the <config repeat> attribute of the Depot Autopilot.
To get a hint which build components (TEST_BUILDS) and which boot modules
(TEST_MODULES) you may want to enter for a given test package, you may have
a look at the package recipe:
! repos/<REPO>/recipes/pkg/<TEST_PKG>/archives
! repos/<REPO>/recipes/pkg/<TEST_PKG>/runtime (<content> tag)
