perf build-id: Move the routine to find DSOs with hits to the lib Because 'perf record' will have to find the build-ids in after we stop recording, so as to reduce even more the impact in the workload while we do the measurement.

perf tools: Rename perf_event_ops to perf_tool To better reflect that it became the base class for all tools, that must be in each tool struct and where common stuff will be put.

perf annotate: Use build-ids to find the right DSO We were still using the pathname found on the MMAP event, that could not be the one we used when recording, so use the build-id cache for that, only falling back to use the pathname in the MMAP event if no build-ids are available. With this we now also are able to do secure, seamless offline annotation.
