[PATCH 0/2] MR5112: DBI substreams in PDB files.

[eric pouech (＠epo)]

We used to expect a fixed number of DBI substreams (the expected number depended
on the DBI header version).
Recent MSVC generate a different number as we expected.
Implement a more flexible scheme where we allow any number of streams.
This lets these recent PDB files to be properly displayed by winedump, and
loaded/parsed by dbghelp.
