81d0996901 Assorted integration fixes.
MSVC does not like bitfields with extra bits in them, so it made the GptEntry struct too big.

Fixed a missing return value in LoadFirmware().

Added some debug output.

Fixed calls to SetupTPM().

Tested with 'make && make runtests'.  No errors.

f7a45cc01d Reduce attributes size to comply with msc limitations.
It turned out that shared verified boot library fails to
work properly when compiled by msc in BIOS environment.

The culprit was identified as failing 64 bit logical
operations by preprocessor. It is probably possible to
come up with a certain compile flag set to fix the
operations, but it is not easy to modify and control the BIOS
compilation environment.

The alternative solution is to limit the size of the field
in question to 16 bits (especially since this is the only
part of the attributes field which is supposed to be
altered by firmware.

A union is being introduced in firmware/lib/cgptlib/include/gpt.h:GptEntry to allow
accessing the field both as a 64 bit entity and a top
16 bit field. All places where this field is used are
being modified appropriately.

tests/Makefile is being fixed to allow controlling test run
from the top level directory.

Tested by building everything and running tests.
All tests pass.

f1372d9109 Nearly complete rewrite of cgpt tool.
This fixes a number of bugs, adds a bunch of commands, and essentially makes
cgpt ready to use as a replacement for gpt. Still to do is to add commands
and options that will let it generated intentionally bad partitions, for use
in testing.

31066a4515 Ignore the AlternateLBA field in the GPT headers.
We know where to look, and we'll look there regardless. We don't care where
the header creator thinks it should be.

Update tests to match.

Oh, and don't assume that I mean "/dev/FOO" if I just say "FOO". That's
really annoying.

3dcf9dce04 Much rearranging of cgptlib. Passes all its (new) unit tests.
Also includes part of LoadKernel(), which I'll split into a separate
CL.  With some hacks, gets into VerifyKernel() before dying because
I'm not passing in the right key blob.

cgptlib is now pretty stable, and worth looking at.  LoadKernel() less so.

Thanks,
   Randall
