libperf: Adopt perf_mmap__put() function from tools/perf
Move perf_mmap__put() from tools/perf to libperf.
Once perf_mmap__put() is moved, we need a way to call application
related unmap code (AIO and aux related code for eprf), when the map
goes away.
Add the perf_mmap::unmap callback to do that.
The unmap path from perf is:
perf_mmap__put (libperf)
perf_mmap__munmap (libperf)
map->unmap_cb -> perf_mmap__unmap_cb (perf)
mmap__munmap (perf)
Committer notes:
Add missing linux/kernel.h to tools/perf/lib/mmap.c to get the BUG_ON
definition.
