browser. And will carry some more in the next patches.

Better name it browser_disasm_line, i.e. something derived from
disasm_line, that specializes it.

And implement the jump one, where if the operands string is not passed,
a compact form that uses just the target address is used.

Right now this is toggled via the 'o' option in the annotate browser,
switching from:

The lines in objdump have this format:

    ffffffff8126543f:       jne    ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
    ffffffff81265494:       mov    %rdi,%rcx

Since we now have objdump_line allowing tools to print the offset
independently from the rest of the line, allow toggling a view where
just offsets from the start of the function are shown:

     2f:       jne    ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
     84:       mov    %rdi,%rcx

The offset view will be the default as soon as operations that deal with
offsets in a function are handled accodringly, i.e. in offset view the
above will become:

     2f:       jne    __list_del_entry+0x84
<SNIP>
     84:       mov    %rdi,%rcx

And then a follow up patch will allow navigating thru jumps, just like
we handle callq instructions.

In hists browser, press hotkey 'a' to annotate current symbol.

Now it causes segment fault if 'a' is pressed on a null symbol.

Here are 2 small bugs:
- In perf_evsel__hists_browse, the condition check after 'a' is pressed
  is not correct, we should check ->sym instead of ->map.
- In symbol__tui_annotate we must check whether sym is NULL or not
  before getting annotation structure.

This patch fixes above 2 small bugs.

Rename "struct sym_ext" to "struct source_line", to give it a meaningful

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.

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.
