Subject[PATCH 06/83] perf annotate: Add symbol__annotate function
Date
From: Jiri Olsa <jolsa@kernel.org>

Add symbol__annotate function to have generic annotation function to be
called for all annotation sources.

It calls the generic annotation init and then the specific annotation
data retrieval function.
