  Provide leading and trailing zero bit count functions to abstract away
compiler specific implementations.

Include basic unit test for new leading/trailing zero bit count functions.

v2:
  * use unsigned int instead of unsigned (checkpatches)
  * match multiple include guard naming convention to rte_common.h
  * add explicit extern "C" linkage to rte_bitcount.h
    note: not really needed but checkpatches required
  * add missing space around '-'
