perf tools: No need to include internal/lib.h from util/util.h

2019-09-25T12:51:48+00:00

That was done just to have users of writen() and readn(), that before
had their prototypes in util/util.h to get it without having to add an
include for internal/lib.h, but the right way is to add it and by now
all places already do it.

Fix a fallout were readlink() was used but unistd.h was being obtained
by luck thru util.h -> internal/lib.h, now to check why unistd.h is
being included there...

libperf: Move 'page_size' global variable to libperf

2019-09-25T12:51:48+00:00

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.

2019-09-25T12:51:48+00:00

internal functions.

Move 'struct perf_sample_id' to internal/evsel.h header and change
'struct perf_sample_id::evsel' to 'struct perf_evsel' and the related
code that touches it.

perf evlist: Adopt backwards ring buffer state enum

2019-09-25T12:51:45+00:00

As this isn't used at all in mmap.h but in evlist.h, so to cut down the
header dependency tree, move it to where it is used.

Also add mmap.h to the places using it but previously getting it
indirectly via evlist.h.

Add missing pthread.h to evlist.h, as it has a pthread_t struct member
and was getting the header via mmap.h.

Noticed while processing a Jiri's libperf batch touching mmap.h, where
almost everything gets rebuilt because evlist.h is so popular, so cut
down't this rebuild the world party.
