Bitwise operation APIs are defined and used in a lot of PMDs,
which caused a huge code duplication. To reduce duplication,
this patch consolidates them into a common API family and use
it for all the PMDs(we started with a few selectively).
v7:
1. Change the API's head file to 'rte_pmd_bitops.h' as a common-
but-not-public file.
2. Replace C11 atomic operations with 'volatile'. As the use cases
are limited to PMDs, a 'volatile' is sufficient.
v5,v6:
Trim 'unsigned long' in PMDs down to 'uint32_t', as on mainstream
64-bit OS, 'unsigned long' is 64-bit in size, but the 32-bit OS
expects 32-bit 'unsigned long' argument.
v4:
Introduce uint32_t/uint64_t *addr when definiting bit operation
APIs.
v3:
1. Change the API's head file back to rte_bitops.h, then implement
both 32-bit and 64-bit operations with and without C11 atomic
memory ordering.
2. Add multi-core test case for bit operations which implemented
with memory ordering.
3. Modify the doc of both APIs and test cases.
v2:
1. Add doxygen comments for the rte bit operation API.
2. Add test cases for common rte bit operation API.
3. Change the header file to rte_io_bitops.h and the operation to
rte_io_set_bit() etc., as the API uses barriers inside and the
barriers are only needed for IO operations.
4. Use an well defined uint_NN_t type.

lib/eal: implement the family of PMD bit operation APIs
test/pmdbitops: add PMD bit operation test case
net/axgbe: use common rte bit operation APIs instead
net/bnx2x: use common rte bit operation APIs instead
net/qede: use common rte bit operation APIs instead
net/hinic: use common rte bit operation APIs instead
