[dpdk-dev] [RFC] malloc: add malloc and free log function

[Xueming Li]

DPDK uses second level memory allocation management, this makes
regular memory profiler tool not applicant. This patch trys to
provide a lightweight malloc and free logging, then show leaked
memory entries based on logs.

This tool only target to malloc and free tracking, for memzone
used by ring and mempool, "dump_memzone" in testpmd list them.

There will be another example that enable and dump tracking as
secondary process.

This tool came from Mellanox internal Hackathon, thanks Shahaf Shuler
<shahafs at mellanox.com> who provided the idea.
