On powerpc, libio.h was conditionally included, but could be removed
completely as it is unneeded. Also, the included of stdlib.h was changed

In order to differentiate source lines from asm line, print them with
gray color. To do this, it needs to be escaped since sometimes it
contains "<" and/or ">" characters so that it should not be considered
as a markup tags. Use glib's g_markup_escape_text() for this.

Show multiple annotation result for each evsel. Each result represents
the most frquently sampled symbol/function for the evsel and it will be
shown in a tab window.
For this add a reference to main container (notebook) to the pgctx. At
the first call to annotate browser, hist_entry__find_annotations() will
setup a new browser, and next calls will add new tabs to the browser.
But it requires final perf_gtk__show_annotations() to start processing
GUI events.

Basic implementation of perf annotate on GTK2. Currently only
shows first symbol. Add a new --gtk option to use it.

When perf annotate runs with no vmlinux file it cannot annotate kernel
symbols because the kallsyms only provides symbol addresses. So it
recommends to run perf buildid-cache to install proper vmlinux image.
But running perf buildid-cache -av vmlinux as the message gives me a
following error:
$ perf buildid-cache -av /home/namhyung/build/kernel/vmlinux
Couldn't add v: No such file or directory
Since the -a option receives a parameter, 'v' should not be after the
option.
In addition -a option is not work for this case since the build-id cache
already has a kallsyms with same build-id so it'll fail with EEXIST.
Use recently added -u (--update) option for it.

When adding vmlinux file to build-id cache, it'd be fail since kallsyms
dso with a same build-id was already added by perf record.
So one needs to remove the kallsyms first to add vmlinux into the cache.
Add --update option for doing it at once.

A sweep of the kernel for regex "kcalloc(sizeof" turned up 2 reversed
args, fixed in commit d3d09e1820 ("EDAC:
Fix kcalloc argument order") and also fixed in the networking commit
a1b1add07f ("gro: Fix kcalloc argument
order").
I know that was the regex used, because on seeing the 1st of these
changes, I wondered "how many other instances of this are there" and I
happened to just use "calloc(sizeof" as a regex and it in turn found
these additional reversed args instances in the perf code.
In the kcalloc cases, the changes are cosmetic, since the numbers are
simply multiplied. I had no desire to go data mining in userspace to
see if the same thing held true there, however.

The ':GH' group modifier handling was just recently fixed, adding some
autommated tests to keep it that way. Adding tests for following events:
"{cycles,cache-misses:G}:H"
"{cycles,cache-misses:H}:G"
"{cycles:G,cache-misses:H}:u"
"{cycles:G,cache-misses:H}:uG"
Plus fixing test__group2 test.
