Subject: [PATCH 03/53] perf srccode: Move struct definition from map.h to srccode.h

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To reduce the header dependencies, since we already have a srccode.h
header, then there is where the 'struct srccode_state' should be, and
map.h, that is more widely used should have just a forward declaraion
of 'struct srccode_state'.
