Subject[PATCH 03/16] perf maps: Introduce maps__find_symbol_by_name()
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

Out of map_groups__find_symbol_by_name(), so that we can turn this later
one first into a call to maps__find_symbol_by_name(MAP__FUNCTION) +
MAP__VARIABLE, and then to just one call, we'll merge MAP__FUNCTION with
MAP__VARIABLE maps, to simplify the code.
