From: Arnaldo Carvalho de Melo <[email protected]>
Since we'll need it when implementing the live annotate TUI browser.
This also simplifies things a bit by having the list head for the source
code to be in the dynamicly allocated part of struct annotation, that
way we don't have to pass it around, it can be found from the struct
symbol that is passed everywhere.

From: Arnaldo Carvalho de Melo <[email protected]>
The live annotation done in 'perf top' needs to limit the context before
lines that aren't filtered out by the min percent filter, if we don't do
that, the screen in a tty often is not enough for showing what is
interesting: lines with hits and a few source code lines before it.
