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
<shah...@mellanox.com> who provided the idea.
V0: initial version
V1: log rte_realloc function
rename log size to req_size, real_size to size(total)
log padding and include padding in total size
rename log "free" field to "type", alloc_free to "paired"
rename malloc_log_index to malloc_log_count
split testpmd part into separate patch
add rte_malloc_log_stop() function
add log entry number check
change log dump detail level from (-1,0,1) to (0,1,2)
