perf symbols: Move map related routines to map.c
Thru series of refactorings functions were being renamed but not moved to map.c to reduce patch noise, now lets have them in the same place so that use of the symbol system by tools can be constrained to building and linking fewer source files: symbol.c, map.c and rbtree.c.
