Subject: [PATCH 26/47] perf dsos: Move the dsos struct and its methods to separate source files
From: Arnaldo Carvalho de Melo <acme@...hat.com>
So that we can reduce the header dependency tree further, in the process
noticed that lots of places were getting even things like build-id
routines and 'struct perf_tool' definition indirectly, so fix all those
too.
