Adding automated test to check the exact number of breakpoint event
overflows and counts.

This test was originally done by Vince Weaver for perf_event_tests.

Adding automated test for breakpoint event signal handler checking if
it's executed properly.

The test is related to the proper handling of the RF EFLAGS bit on
x86_64, but it's generic for all archs.

First we check the signal handler is properly called and that the
following debug exception return to user space wouldn't trigger
recursive breakpoint.

This is related to x86_64 RF EFLAGS bit being managed in a wrong way.

Second we check that we can set breakpoint in signal handler, which is
not possible on x86_64 if the signal handler is executed with RF EFLAG
set.

This test is inpired by overflow tests done by Vince Weaver.

However since the size of struct source_line is not fixed anymore,

It's almost always used with NULL for both arguments.  Get rid of the
arguments from the signature and use perf_evlist__set_maps() if needed.

Jiri Olsa triggers the following build error:

    SUBDIR ../lib/lk/
    CC debugfs.o
In file included from /usr/include/errno.h:29:0,
                 from debugfs.c:1:
/usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]

This is because enabling buffer overflow checks through _FORTIFY_SOURCE
require compiler optimizations to be enabled too. However, those are
not. Enable them by simply copying the perf optimization level. It can
be expanded later if we want to support debug builds, etc.

page-flags.c had some older version of debugfs_mount copied from perf so
convert it to using the version in the tools library.

This introduces the tools/lib/lk library, that will gradually have the
routines that now are used in tools/perf/ and other tools and that can
be shared.

Start by carving out debugfs routines for general use.

Make attr script to check for 'cpu' when testing event properties. This
will allow us to check the '-C X' option for both record and stat
commands.

Making the attr test script runner to pass proper verbose option. Also
making single '-v' be more reader friendly and display just the test
name.

Making the current output to be display for '-vv'.
