tests/functional: automatically clean up scratch files after tests
The build/tests/functional subdirectories are consuming huge amounts of disk space. Split the location for scratch files into a 'scratch' sub-directory, separate from log files, and delete it upon completion of each test. The new env variable QEMU_TEST_KEEP_SCRATCH can be set to preserve this scratch dir for debugging access if required. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Daniel P.

The test framework will automatically purge any scratch files created during
|
||||
the tests. If needing to debug a failed test, it is possible to keep these
|
||||
files around on disk by setting ```QEMU_TEST_KEEP_SCRATCH=1``` as an env
|
||||
variable. Any preserved files will be deleted the next time the test is run
|
||||
without this variable set.
