The commit 5395a048 ("perf hists: Separate overhead and baseline
columns") makes the "Overhead" column no more the first one, this
caused the test that checks if it is time to show if a histogram
entry has callchains never hits.

Fix it by checking if the 'i' variable is equal to PERF_HPP__OVERHEAD
instead of 0.

Perf uses GNU-specific version of strerror_r(). The GNU-specific strerror_r()
returns a pointer to a string containing the error message.  This may be either
a pointer to a string that the function stores in buf, or a pointer to some
(immutable) static string (in which case buf is unused).

In glibc-2.16 GNU version was marked with attribute warn_unused_result.  It
triggers few warnings in perf:

util/target.c: In function ‘perf_target__strerror’:
util/target.c:114:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result]
ui/browsers/hists.c: In function ‘hist_browser__dump’:
ui/browsers/hists.c:981:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result]

They are bugs.

To avoid having to resort to --stdio, that expands everything, instead
allow the user to go on expanding the relevant callchains and then press
'P' to print that view.

As the hists browser is used for both static (report) and dynamic (top)

events separately.

This allows comparing performance of different applications with each
other.

Previously, the sample count was displayed against an 'Events:' heading.
With this patch, the header now reads (for example):

Samples: 5K of event 'instructions'

If there's an event with no samples in data file, the perf report
command can segfault after entering the event details menu.

Following steps reproduce the issue:

 # ./perf record -e syscalls:sys_enter_kexec_load,syscalls:sys_enter_mmap ls
 # ./perf report
 # enter '0 syscalls:sys_enter_kexec_load' menu
 # pres ENTER twice

Above steps are valid assuming ls wont run kexec.. ;)

The check for sellection to be NULL is missing. The fix makes sure it's
being check. Above steps now endup with menu being displayed allowing
'Exit' as the only option.

When building on my Debian/mips system, util/util.c fails to build
because commit 1aed2671 (perf kvm: Do
guest-only counting by default) indirectly includes stdio.h before the
feature selection in util.h is done.  This prevents _GNU_SOURCE in
util.h from enabling the declaration of getline(), from now second
inclusion of stdio.h, and the build is broken.

There is another breakage in util/evsel.c caused by include ordering,
but I didn't fully track down the commit that caused it.

The root cause of all this is an inconsistent definition of _GNU_SOURCE,
so I move the definition into the Makefile so that it is passed to all
invocations of the compiler and used uniformly for all system header
files.  All other #define and #undef of _GNU_SOURCE are removed as they
cause conflicts with the definition passed to the compiler.

All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64
and _GNU_SOURCE) are needed by the python glue code too, so they are
moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS
are removed.

This gives me a clean build on x86_64 (fc12) and mips (Debian).

And also no leed to show the [.] (level: k, . for userspace) when
showing just one DSO.

We lost that when we move it outside hist_entry__snprintf, but better
leave it untangled of 'perf diff' stuff (pair_hist, etc).

TUI help states for multiple event sessions the TAB/UNTAB keys are used
to switch events. For single event sessions (e.g., the default) the tab
key currently causes the tui to exit. Change that to do nothing since
there is not no second event to switch to.

Since with dynamic addition of new hist entries we need to apply those
filters as we merge new batches of hist_entry instances, for instance in
perf top.

And like it was in the old top.

Another change so that the familiarity with the old visual is maintained.

We can't have color correctly set there because in libslang (and in a future
GUI) the colors must be set on a separate function call, so move that part to a
separate function and make the stdio fprintf function call it.

The selection and scroll bar are really needed only when the user starts
navigating, before that it just provide distractions.

This also brings the initial screen to look more like the stdio UI,
which more people are used to.

The new code is flexible enough that menu like browsers can opt out and
start with those UI elements.
