Dynamically allocate source_line_percent according to a number of group
members and save nr_pcnt to the struct source_line.  This way we can
handle multiple events in a general manner.

However since the size of struct source_line is not fixed anymore,
iterating whole source_line should care about its size.

The %name-prefix "prefix" syntax is not available on bison 2.3 and
older. Substitute with the -p "prefix" command-line option for
compatibility with older versions of bison.

This patch fixes this build error with older versions of bison.

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.

So that we fix this regression:

A sweep of the kernel for regex "kcalloc(sizeof" turned up 2 reversed
args, fixed in commit d3d09e18 ("EDAC:
Fix kcalloc argument order") and also fixed in the networking commit
a1b1add0 ("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.

Let the perf_evsel::exclude_GH only prevent the reset of exclude_host
and exclude_guest attributes in case they were already set.

We cannot reset their values to 0, because they might have other
defaults set by event_attr_init.

This patch adds:
- cpu_map__get_socket: get socked id from cpu
- cpu_map__build_socket_map: build socket map
- cpu_map__socket: gets acutal socket from logical socket

Those functions are used by uncore and processor socket-level
aggregation modes.
