Only a 'struct perf_cmp_map' forward allocation is necessary, fix the
places that need the header but were getting it indirectly, by luck,
from env.h.

The util/cpumap.h file doesn't use anything in refcount.h not in
debug.h, it needs just a forward reference to 'struct cpu_map_data',
that is defined in util/event.h and cpumap.h was getting indirectly via,
of all things, debug.h

Moving the following functions from tools/perf:
cpu_map__new()
cpu_map__read()
to libperf with the following names:
perf_cpu_map__new()
perf_cpu_map__read()
Committer notes:
Fixed up this one:
tools/perf/arch/arm/util/cs-etm.c

Rename struct cpu_map to struct perf_cpu_map, so it could be part of
libperf.
Committer notes:
Added fixes for arm64, provided by Jiri.

In places where the equivalent was already being done, i.e.:
free(a);
a = NULL;
And in placs where struct members are being freed so that if we have
some erroneous reference to its struct, then accesses to freed members
will result in segfaults, which we can detect faster than use after free
to areas that may still have something seemingly valid.

bitmap_zero() is called after bitmap_alloc() in perf code. But
bitmap_alloc() internally uses calloc() which guarantees that allocated
area is zeroed. So following bitmap_zero is unneeded. Drop it.
This happened because of confusing name for bitmap allocator. It
should has name bitmap_zalloc instead of bitmap_alloc.
This series:
https://lkml.org/lkml/2018/6/18/841
introduces a new API for bitmap allocations in kernel, and functions
there are named correctly. Following patch propogates the API to tools,
and fixes naming issue.

Adding mem2node object automated test.
The test prepares few artificial nodes - memory maps and verifies the
mem2node object returns proper node values to given addresses.
