libperf: Adopt the readn()/writen() functions from tools/perf 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.

libperf: Use sys/types.h to get ssize_t, not unistd.h The sys/types.h header looks more sensible, from its name we can gather it should be there because of some needed typedef, and it is much smaller than unistd.h, so use it and fix up the fallout in places where it was being used for something else entirely but being obtained by sheer luck, indirectly.

libperf: Move 'page_size' global variable to libperf 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.
