[PATCH 03/16] perf maps: Introduce maps__find_symbol_by_name()

From: Arnaldo Carvalho de Melo
Date: Wed Sep 30 2015 - 17:58:46 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

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.
