[PATCH v1 0/8] perf tools: Cleanup dso debug info access

[Namhyung Kim <namhyung@kernel.org>]

Hello,

This is a preparation for DSO file access cleanup work.  IIUC DSO
access has three types - symbol table, binary data and debug info.
Those information can be placed separately like stripped binaries and
split debug files.  I've added dbginfo_type to DSO to track location
of debug info like others.

I'm sending this out before it grows too much.  This patchset focuses
on debuginfo open path.  Once it looks good to others, I'll update
other places accessing DWARF info to use this info and cleanup other
file type accesses too.

Thanks,
Namhyung
