Vladimir Sementsov-Ogievskiy 52f2b89614 tests/perf: Test lseek influence on qcow2 block-status 
Block layer may recursively check block_status in file child of qcow2,
if qcow2 driver returned DATA. There are several test cases to check
influence of lseek on block_status performance. To see real difference
run on tmpfs.

Tests originally created by Kevin, I just refactored and put them
together into one executable file with simple output.
