Special runCmd() for build perf tests which doesn't raise an
AssertionError when the command fails. This causes command failures to
be detected as test errors instead of test failures. This way "failed"
state of tests is reserved for future making it possible to set e.g.
thresholds for certain measurement results.

The new class is derived from unittest.TextTestResult class. It is
actually implemented by modifying the old BuildPerfTestRunner class
which, in turn, is replaced by a totally new simple implementation
derived from unittest.TestRunner.

Rename BuildPerfTest to BuildPerfTestCase and convert it to be derived
from TestCase class from the unittest framework of the Python standard
library. This doesn't work with our existing testcases or test runner
class and these need to be modified, too.

Using this option the script appends test results into a 'global results
file'. A CSV-formatted output of the results. This option is to provide
compatibility with the old build-perf-test.sh.

BuildPerfTestRunner determines these from the Git repository under which
it is being run (i.e. where the build directory exists). The branch and
revision may be defined/overridden with OE_BUILDPERFTEST_GIT_BRANCH
and OE_BUILDPERFTEST_GIT_BRANCH environment variables, if needed. This
makes it possible to run the build performance test script even if the
top directory is not a git repository clone, for example.

The new class is responsible for actually running the tests and
processing their results. This commit also adds a decorator function for
adding new tests. No automatic test discovery, at least yet.

Extend BuildPerfTest class with a new method for measuring the system
resource usage of a shell command to BuildPerfTest class. For now,
easurement of the elapsed time is done with the Gnu time utility,
similarly to the build-perf-test.sh shell script. And, it currently only
records the elapsed (wall clock).
The measured values (currently, only the elapsed time) is actually a
dictionary, making it possible to extend it with additional resource
values, e.g. cpu time or i/o usage, in the future. In addition to the
actual values of the measurement each record contains a 'name' and
'legend' where name is supposed to function as a common key or id over
test runs, making comparison and trending easier, for example. Legend is
supposed to be a short human readable description.

Add a new utility class for dropping Linux kernel caches. It uses sudo
and tee to write to the drop_caches file. Checking if the user has the
permissions to drop caches (without a password) is done by trying to
writing an invalid value to the drop_caches file. This way, we will find
if writing (with tee) is possible but not really dropping caches, yet.
User can avoid giving the password by adding something like:
<user> ALL = NOPASSWD: /usr/bin/tee /proc/sys/vm/drop_caches
to the system sudoers file.
