2019-09-25libperf: Merge libperf_set_print() into libperf_init()Jiri Olsa4-10/+10

2019-09-25libperf: Use sys/types.h to get ssize_t, not unistd.hArnaldo Carvalho de Melo2-1/+2
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.

2019-09-25perf tools: No need to include internal/lib.h from util/util.hArnaldo Carvalho de Melo2-1/+1
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...

2019-09-25libperf: Move 'page_size' global variable to libperfJiri Olsa28-25/+36
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.

2019-09-25perf evlist: Adopt backwards ring buffer state enumArnaldo Carvalho de Melo26-29/+53
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.

All traceevent plugins code is moved to tools/lib/traceevent/plugins subdirectory. It makes traceevent implementation in trace-cmd and in kernel tree consistent. There is no changes in the way libtraceevent and plugins are compiled and installed. Committer notes: Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf target for the plugin dynamic list file. Problem noticed when cross building to aarch64 from a Ubuntu 19.04 container.
