2019-08-29perf tools: Remove perf.h from source files not needing itArnaldo Carvalho de Melo
With the movement of lots of stuff out of perf.h to other headers we ended up not needing it in lots of places, remove it from those places.

2019-08-29perf tools: Move everything related to sys_perf_event_open() to perf-sys.hArnaldo Carvalho de Melo
And remove unneeded include directives from perf-sys.h to prune the header dependency tree. Fixup the fallout in places where definitions were being used without the needed include directives that were being satisfied because they were in perf-sys.h.

2019-08-26perf tests: Fixes hang in zstd compression test by changing the source of ↵James Clark
random data Running 'perf test' with zstd compression linked will hang at the test 'Zstd perf.data compression/decompression' because /dev/random blocks reads until there is enough entropy.

In places where the equivalent was already being done, i.e.: free(a); a = NULL; And in placs where struct members are being freed so that if we have some erroneous reference to its struct, then accesses to freed members will result in segfaults, which we can detect faster than use after free to areas that may still have something seemingly valid.

2019-06-25tools perf: Move from sane_ctype.h obtained from git to the Linux's originalArnaldo Carvalho de Melo
We got the sane_ctype.h headers from git and kept using it so far, but since that code originally came from the kernel sources to the git sources, perhaps its better to just use the one in the kernel, so that we can leverage tools/perf/check_headers.sh to be notified when our copy gets out of sync, i.e. when fixes or goodies are added to the code we've copied. This will help with things like tools/lib/string.c where we want to have more things in common with the kernel, such as strim(), skip_spaces(), etc so as to go on removing the things that we have in tools/perf/util/ and instead using the code in the kernel, indirectly and removing things like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements are made to the original code. Hopefully this also should help with reducing the difference of code hosted in tools/ to the one in the kernel proper.
