perf annotate: Add TUI interface
When annotating multiple entries, for instance, when running simply as:
$ perf annotate
the right and left keys, as well as TAB can be used to cycle thru the
multiple symbols being annotated.
If one doesn't like TUI annotate, disable it by editing ~/.perfconfig
and adding:
[tui]
annotate = off
Just like it is possible for report.
