In this first commit, I use the plugin to verify the consistency of our
SAL_CALL annotations.
The point being to make the next commit more mechanical in nature,
purely using the rewriter.

There are various chunks of unix-only code that have never had to be
compiled by MSVC, hence the inconsistencies.

In bridges, I had to inline some typedefs to make the verification code
happy, since it cannot see into typedefs.
