https://git.shady.money/linux/atom?h=v5.42019-09-25T12:51:48Zlibperf: Move 'page_size' global variable to libperf2019-09-25T12:51:48ZJiri Olsajolsa@kernel.org2019-08-06T13:25:25Zurn:sha1:20f2be1d48ec293b5a935595bd0c2e2915ffa77c
We need the 'page_size' variable in libperf, so move it there.
Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.
Committer notes:
Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.

libperf: Adopt the readn()/writen() functions from tools/perf2019-07-29T21:34:46ZJiri Olsajolsa@kernel.org2019-07-21T11:24:47Zurn:sha1:c03538b1f1a7e0e996a8d6feb20cf001d4b14939
Move the readn()/writen() functions into libperf.
Keep those non-namespaced names because they will be shared only between
perf and libperf.
Again, these are not exported functions.
