Subject: [PATCH 19/46] perf sort: Introduce addr_map_symbol__srcline() to make code more compact

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

Since we have 'struct addr_map_symbol' and the srcline sort order keys
all operate on those, make the code more compact by introducing a
function that receives a pointer to such struct and expands the
arguments to map__srcline().
