Introduce OS-independent wrappers for memory management operations used

Windows uses different APIs for memory mapping and reservation, while
Unices reserve memory by mapping it. Introduce EAL private functions to
support memory reservation in common code:
* eal_mem_reserve()
* eal_mem_free()
* eal_mem_set_dump()
Wrappers follow POSIX semantics limited to DPDK tasks, but their
signatures deliberately differ from POSIX ones to be more safe and
expressive.

Also, please check that you're using rte_strerror with rte_errno :)
