perf top: Live TUI Annotation

Browse Source 
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.
