The list of libraries in LDLIBS was generated from the DEPDIRS-xyz
variable. This is valid when the subdirectory name match the library
name, but it's not always the case, especially for PMDs.
The patches removes this feature and explicitly adds the proper
libraries in LDLIBS.
Some DEPDIRS-xyz variables become useless, remove them.

Octeontx mempool pmd need mailbox for pool setup.
That mailbox was defined at drivers/event/octeontx.
So mempool has dependency on event/octeontx driver and
commit:8700239f7767 has added make rule which makes sure event/*
get build before mempool, but this rule introduces
cyclic dependency and may create problem to future
feature addition in drivers/Makefile.
Same problem noticed and reported in below thread:
http://dpdk.org/ml/archives/dev/2017-October/079187.html
The patch solves problem by moving mbox definition from
drivers/event/octeontx to drivers/mempool/octeontx.
Moving mbox files involves below changes:
* Renamed ssovf_mbox.[ch] --> octeontx_mbox.[ch]
* Renamed ssovf_probe.c --> octeontx_ssovf.c
* Introduced pool logger file.
* Moved API from rte_pmd_octeontx_ssovf_version.map to
rte_mempool_octeontx_version.map.
* Respective Makefile changes done in
drivers/event/octeontx/Makefile and drivers/mempool/octeontx/Makefile.

Some of the internal toolchain versions create unaligned
memory access fault when copying from 17-31B buffer using memcpy.
Subsequent patches in this series will be using 17-31B mbox message.
Since the mailbox message copy comes in slow path, changing memcpy to
byte-per-byte copy to workaround the issue.
