Move existing bit manipulation, log and npow functions from
rte_common.h to rte_bitops.h
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.
v4:
* combine unit test commit into function addition commit
v3:
* rename to use 32/64 instead of l/ll suffixes
* add new functions to rte_bitops.h instead of new header
* move other bit functions from rte_common.h to rte_bitops.h
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 '-'

eal: move bit operation functions from common to bitops header
