commit 38a258e72245ef143ab17f008f5b894a23dd98a9
Author: Aaron Durbin

commonlib: prepare for cbfstool inclusion

Some of the files need to be adjusted so that they can be used
    both in cbfstool as well as coreboot proper. For coreboot,
    add a <sys/types.h> file such that proper types can be included
    from both the tools and coreboot. The other chanes are to accomodate
    stricter checking in cbfstool.

BUG=chrome-os-partner:48412
    BUG=chromium:445938
    BRANCH=None
    TEST=Built on glados including tools. Booted.
