[PATCH 0/7] MR7698: PDB rewrite #6.

[eric pouech (＠epo)]

This serie mainly moves line information for top level function
(not including the inlined parts) into the new PDB reader.

In details:
- cleaning up current internal private structure for line information
  (in order to share it with PDB backend)
- introduce methods to get line info from address, move to next/prev
  location, enumeration of line numbers and source files.

Note for source files enumeration:
- current implementation still needs some more fixes (no full scoping,
  but that's unrelated to PDB rewrite)
- fixes by module scoping
- it still uses the global source hash table (as there isn't one
  in PDB). No plan to improve that for now.
