[dpdk-dev] [RFC v2 2/2] app/testpmd: support malloc and free tracking log

[Xueming Li <xuemingl@mellanox.com>]

New CLI commands to manipulate malloc tracking log:

dump_malloc start <n>: start malloc tracking with number of buffers
dump_malloc dump <n>:  dump mmalloc tracking log with detail level
dump_malloc stop:      stop malloc tracking
