Since we'll need it when implementing the live annotate TUI browser.
This also simplifies things a bit by having the list head for the source
code to be in the dynamicly allocated part of struct annotation, that
way we don't have to pass it around, it can be found from the struct
symbol that is passed everywhere.

GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf
due to the -Werror=unused-but-set-variable flag.
I've gone through and annotated some of the assignments that had side
effects (ie: return value from a function) with the __used annotation,
and in some cases, just removed unused code.
In a few cases, we were assigning something useful, but not using it in
later parts of the function.

They will be used by perf top, so that we have just one set of routines
to do annotation.
Rename "struct sym_priv" to "struct annotation", etc, to clarify this
code a bit.
Rename "struct sym_ext" to "struct source_line", to give it a meaningful
name, that clarifies that it is a the result of an addr2line call, that
is sorted by percentage one particular source code line appeared in the
annotation.
And since we're moving things around also rename 'sym_hist->ip' to
'sym_hist->addr' as we want to do data structure annotation at some
point.

Fix it by explaining what can be happening and giving the number of processed
and lost events.
Also holler if unknown events were found, that can be due to processing a
perf.data file collected using a newer tool where newer events got added on
reporting using an older perf tool, that or a bug, so ask for a report to be
made.
Works on both --tui and --stdio.

When looking at a callchains enabled perf data file one can find it
tiresome to start with all callchains collapsed and then to have to go
one by one expanding them.
So associate 'E' with "Expand all callchains" and 'C' with "Collapse all
callchains".
This way now one can have the top level view and then switch to/from
having all callchains expanded.
More work is needed to allow expanding just from one branch down to its
leaves.

This makes the usual idiom for specifying a series of key codes to exit
ui_browser__run() for specialized processing (search, annotate, etc) or
plain exiting the browser more compact.
It also abstracts away some more libnewt operations. At some point we'll
also replace NEWT_KEY_foo with something that can be mapped to NEWT or,
say, gtk.

As part of ongoing effort to reduce the coupling with libnewt, browsers
are being changed to return the exit key.
The annotate browser is not returning it as expected by builtin-annotate
when annotating multiple symbols (when 'perf annotate' is called without
specifying a symbol name).
Fix it by returning the exit key and also adding the RIGHT key as a exit
key so that going to the next symbol in the TUI can work again.

The annotate TUI now starts centered on the line with most samples, i.e.
the hottest line in the annotated function. Pressing TAB will center on
