171b3be9c4 perf symbol: Move sym_entry->skip to symbol->ignore
While going thru each of the sym_entry fields looking to reduce it to
the set of entries needed when in an active symbols list, 'skip' should
really be in symbol, as we set it when loading the symtab.

And the space used by the basic symbol allocation remains the same as
we had 5 bytes of padding.

8b8ba4a9a5 perf top: Remove redundant syme->origin field
We can get it from syme->map->dso->kernel (that should be renamed to
origin, but leave this for another patch).

We can get that counter index from perf_top->sym_evsel->idx instead.

c97cf42219 perf top: Live TUI Annotation
Now one has just to press the right key, 'a' or Enter on the main 'perf
top --tui' screen to live annotate the symbol under the cursor.

The annotate window starts centered on the hottest line (the one with
most samples so far) then TAB and shift+TAB can be used to go to the
prev/next hot line.

Pressing 'H' at any point will center again the screen on the hottest
line.

ce6f4fab40 perf annotate: Move locking to struct annotation
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.

c0443df1b6 perf top: Introduce slang based TUI
Disabled by default as there are features found in the stdio based one
that aren't implemented, like live annotation, filtering knobs data
entry.

Annotation hopefully will get somehow merged with the 'perf annotate'
code.

To use it:

perf top --tui
