Parameters to be tested:
no_lock:
Copy with no locking mechanism. There is no way to test this thoroughly here.
This will be tested with multiple threads later in test_rece_cond.py.
no_checksum:
Don't check md5-hash/size/mtime to skip copying (even if file already exists on destination).
make_md5_file:
Make md5 file on destination only when it's REQUIRED.
It's required only if we need to compare md5 hash of source and target.
