The gcc complains about small auto-var strings being allocated from stack space.
Make them const to avoid this:

 | CC util/ui/util.o
 | cc1: warnings being treated as errors
 | util/ui/util.c: In function ‘ui__dialog_yesno’:
 | util/ui/util.c:108: error: not protecting function: no buffer at least 8 bytes long
 | make: *** [util/ui/util.o] Error 1

The real bug is in the newtWinChoice() ABI - but that's an
externality we cannot fix here, so we use this workaround.

We wrap it in libslang.h because we need to deal with older slang release
where HAVE_LONG_LONG is referenced as:

So we need to define it.

Noticed when rebuilding the perf tools on a RHEL5 machine.

They are useless and take away precious columns and lines, so stop using
windows.

One more step in removing newt code, that after all is not being useful
at all for the coalescing TUI model in perf.

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.

Not everytime we show the callchains, removing duplicated initialization
of this field.

Its way too stupid to use rb_first() for just caching if there are
children, use the cheaper RB_EMPTY_ROOT() instead.

It wasn't setting the ms.has_children for the hist_entry itself, just
for the callchain

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.

Make all browsers return the exit key uniformly and remove the
newtExitStruct parameter, removing one more newt specific thing from the
ui API.

Browsers don't have to deal with absolute coordinates, just using (row,
column) and leaving the rest to ui_browser is better and removes one
more UI backend detail from the browsers.

Also shorten the percent_color setting idiom, removing some more direct
libslang calls.
