[LTP] [RFC PATCH 00/13] Convert LTP kernel/mem/testcase to New API

[Li Wang]

This patchset is on purpose to convert lib/mem.c to new API, and the follows
are all related testcase which using the memory test library. As you can see,
one converted commit belong to a common subject(locatd in the same dir) at once.

Btw, I have tried to do cleanup/reorg for most of them, but it probably still not
perfect by now, that's because my knowledge is limited. Anyway, before send out,
test looks good(only two failures) from my x86_64(15G RAM, 2 numa nodes) box:

Seems the failed reason in oom02/5 is not testcase issue, it just because New API sets
test time in 5mins.
