libperf: Adopt perf_evlist__mmap()/munmap() from tools/perf
Add libperf's version of perf_evlist__mmap()/munmap() functions and
exporting them in the perf/evlist.h header.
It's the backbone of what we have in perf code. The following changes
will add needed callbacks and then we'll finally switch the perf code to
use libperf's version.
Add mmap/mmap_ovw 'struct perf_mmap' object arrays to hold maps for
libperf's evlist.
