Compare the total time spent on iterating a big file tree
with 3 different time iterators:
- Utils::SubDirFileIterator
- manually written iterator using QDir::entryInfoList()
- QDirIterator
The iterator run through about one million files (including
about ~100K directories). The more files above this
number to be iterated over, the bigger the relative time
difference of SubDirFileIterator compared to other iterators.
The number of generated files depends on the running
machine's core number. In my case:
Number of cores: 24
Number of generated files: 898753
Number of generated directories: 112345
Time spent on generating file tree: ~2 seconds
Time spent on iterating using SubDirIterator: ~80 seconds
Time spent on iterating using manual iterator: ~8 seconds
Time spent on iterating using QDirIterator: ~4 seconds
Time spent on removing generated file tree: ~2 seconds

It's not clear what this test is going to do and
how to run it. Besides, it's not working at least
for one year already. There is not a big loss, since
it was utilizing QtcProcess::readDataFromProcess() only.

Previously the runInShell and outputForRunInShell methods were
exclusively processed single threaded, meaning all calls
were processed sequentially. With the multiplexed
helper script we can now run multiple processes simultaneously.
( see tst_manual_deviceshell )
Additionally the new script allows us to capture both
stdout and stderr from commands which was not possible previously.

Add another option to mark a test as manual and use this for some
existing.
Manual tests will not be added as a ctest, but they can still get
executed explicitly.
Beside this allow to use a condition when using add_qtc_test().
