Description of problem:
Currently for creating directory at a given 'path' we only go as far as creating the last component of the 'path' if missing. This was a stop gap arrangement in place of full fledged mkdir(1) -p like functionality.
In fact in glusterd-rebalance.c, we have taken the approach of calling mkdir(1) utility for this. To avoid spawning a new process for the above or settling with an 'incomplete' solution, it would be good to have a C wrapper for mkdir(1) -p functionality in codebase.

Version-Release number of selected component (if applicable):
