[PATCH 0/4] MR4994: Extend supported file formats in SymSrvGetFileIndexInfo().

[eric pouech (＠epo)]

This serie mainly tests and implement support for SymSrvGetFileIndexInfo() 
on a few more file formats.
- .dbg: with test and implementation,
- .pdb (JG format): This format has been replaced by the DS format for more
  than 25 years, so I didn't bother writting tests for generating such
  files (implementation has been tested manually against some existing
  samples).
