Subject[PATCH 06/44] perf annotate: Move annotation_line array from TUI to generic code
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

This is needed to reduce the differences between the TUI mode and the
other annotation UIs, next csets will move that code to the UI-neutral
annotation library. Leaving it in place for now to ease review.
