Subject[PATCH 23/44] perf annotate: Introduce symbol__annotate2 method
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

That does all the extended boilerplate the TUI browser did, leaving the
symbol__annotate() function to be used by the old --stdio output mode.

Now the upcoming --stdio2 output mode should just use this one to set
things up.
