Storing NUMA info within struct numa_node instead of strings. This way
it's usable in future patches.
Also it turned out it's slightly less code involved than using strings.

Storing CPU cache details under perf data. It's stored as new
HEADER_CACHE feature and it's displayed under header info with -I
option:
$ perf report --header-only -I
...
# CPU cache info:
# L1 Data 32K [0-1]
# L1 Instruction 32K [0-1]
# L1 Data 32K [2-3]
# L1 Instruction 32K [2-3]
# L2 Unified 256K [0-1]
# L2 Unified 256K [2-3]
# L3 Unified 4096K [0-3]
...
All distinct caches are stored/displayed.

Out of the code to write the cpu topology map in the perf.data file
header.
Now if one needs the CPU topology map for the running machine, one needs
to call perf_env__read_cpu_topology_map(perf_env) and the info will be
stored in perf_env.cpu.
For now we're using a global perf_env variable, that will have its
contents freed after we run a builtin.
v2: Check perf_env__read_cpu_topology_map() return in
write_cpu_topology() (Kan Liang)

Move this from two globals to perf_env global, that eventually will
be just perf_header->env or something else, to ease the refactoring
series, leave it as a global and go on reading more of its fields,
not as part of the header writing process but as a perf_env init one
that will be used for perf.data-less situations.

Since it can be used separately from 'perf_session' and 'perf_header',
move it to separate include file and object, next csets will try to move
a perf_env__init() routine.
