Arnaldo Carvalho de Melo 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
