a6205a35ba perf record: Rename --initial-delay to --delay 
To be consistent with the equivalent option in 'stat', also, for the
same reason, use -D as the one letter alias.

509051ea84 perf record: Rename --no-delay to --no-buffering 
That is how the option summary describes it and so that we can free
--delay to replace --initial-delay and then be consistent with stat's
--delay equivalent option.

1d027ee9b8 perf probe: Fix build when DWARF support libraries not present 
On a freshly installed system, after libelf-dev is installed we get:

    CC       /tmp/build/perf/util/probe-event.o
  util/probe-event.c: In function ‘try_to_find_probe_trace_events’:

  cc1: all warnings being treated as errors
  make[1]: *** [/tmp/build/perf/util/probe-event.o] Error 1
  make[1]: *** Waiting for unfinished jobs....
  make: *** [install] Error 2

Fix it by enclosing functions only used when those libraries are installed
under the suitable preprocessor define and using __maybe_unused to a function
that is only built when DWARF support is disabled.

1f513b2c1e perf diff: Color the Ratio column 
In

  $ perf diff -c ratio

color the Ratio column using value_color_snprintf(), a new function that
operates exactly like percent_color_snprintf().

At first glance, it looks like percent_color_snprintf() can be turned
into a non-variadic function simplifying things; however, 53805ec (perf
tools: Remove cast of non-variadic function to variadic, 2013-10-31)
explains why it needs to be a variadic function.

6619a53ef7 perf record: Add --initial-delay option 
perf stat has a --delay option to delay measuring the workload.

This is useful to skip measuring the startup phase of the program, which
is often very different from the main workload.

The same is useful for perf record when sampling.

--no-delay was already taken, so add a --initial-delay
to perf record too.
-D was already taken for record, so there is only a long option.

v2: Don't disable group members (Namhyung Kim)
v3: port to latest perf/core
    rename to --initial-delay to avoid conflict with --no-delay

4887805384 perf tools: Add test for building detached source tarballs 
Test one of the main kernel Makefile targets to generate a perf sources
tarball suitable for build outside the full kernel sources.

This is to test that the tools/perf/MANIFEST file lists all the files
needed to be in such tarball, which sometimes gets broken when we move
files around, like when we made some files that were in tools/perf/
available to other tools/ codebases by moving it to tools/include/, etc.

Now everytime we use 'make -C tools/perf -f tests/make' this test will
be performed, helping detect such problems earlier in the devel cycle.

9bb8e5edcf tools lib traceevent: Shut up plugins make message 
Getting rid of following build output:

  $ make O=/tmp/build/perf -C tools/perf/ install-bin
  ...
  make[3]: Nothing to be done for `plugins'.
  make[2]: Nothing to be done for `plugins'.
  ...

which triggers when traceevent library needs to be rebuilt, but we have
plugins built already.

Adding extra 'plugins' target with nop which is visible and triggers in
both Makefile parts (for detached output directory (O=...) the
traceevent Makefile spawns sub make for the build itself).

f33cbe72e6 perf evlist: Send the errno in the signal when workload fails 
When a tool uses perf_evlist__start_workload and the supplied workload
fails (e.g.: its binary wasn't found), perror was being used to print
the error reason.

This is undesirable, as the caller may be a GUI, when it wants to have
total control of the error reporting process.

So move to using sigaction(SA_SIGINFO) + siginfo_t->sa_value->sival_int
to communicate to the caller the errno and let it print it using the UI
of its choosing.

e8e684a58b perf ui/tui: Split help message for perf top and report 
Some hotkeys don't work for perf top so split help messages for them.

It'll be helpful to a future modification.  Also sort the message by
alphabetical order of the hotkey.

5c743cf573 perf ui/tui: Protect windows by ui__lock 
Sometimes perf top TUI breaks display with concurrent help/input window
and pr_* messages since they're not protected by ui__lock.

You can check it by pressing (and not releasing) 'h' key on a "perf top
-vvv" TUI session.
