Reference code drop-in to firmware should make our implementations of Memset() and SafeMemcmp() get used now.

1) kernel_subkey is one of the input parameters; not read off disk. KeyBlockVerify() now verifies it's not NULL unless we're only using the hash.
2) Added a check for kernel size vs. buffer size.
3) Added a check to make sure kbuf_sectors is nonzero.

This is part of the proposed developer-mode installation process, where we
want to detect that whoever is fiddling with the hard drive has already
fiddled with it before. Otherwise, we'll make them wait a bit to prevent
drive-by updates.

Changed TlclRead / TlclWrite to take void* / const void* to reduce typecasts.
Much restructuring of rollback_index.c.

Make vbutil_keyblock handle unsigned blocks. Also enable --unpack option and
add tests for it.
Modify vbutil_kernel to allow unsigned keyblocks, correct usage message,
and fix the --debug option which was somehow disabled.
Update load_kernel_test to accept /dev/null for the public key, to test
non-signed kernel keyblocks.

Also fix a few comments, and make extra debugging work when compiled
in firmware.

Since the kernel vblocks are always padded out to a fixed size, the unused (padded) memory was ending up containing random bytes, leading to vbutil_kernel generating vblocks that are not bit-identical when run with the same inputs.
BUG=none
TEST=see below
1) Use vbutil_kernel with the same set of inputs to generate two alternative vblocks.
2) Compare the 2 files - they must be bitwise identical space. The padding bytes must all be set to 0.
3) Generate a new signed image using the resign_image.sh script under scripts/image_signing. This signed image should be boot and install successfully on a maching running our custom firmware using the same set of root, firmware, and kernel keys.

Also add a script for splitting a firmware image into component firmware data, vblocks and the GBB.
Note: The script uses fmap_decode, a utility to parse flashmap of a firmware image, and a part of the flashmap project:
http://code.google.com/p/flashmap/
BUG=3496
TEST=Tested with newer builds of firmware images with flashmaps enabled. Steps to verify:
1) Use script to re-sign an existing image with a new set of keys.
2) Use unpack_firmwarefd.sh to get individual firmware data and vblocks.
3) Use vbutil_firmware with the new keys. Verification should succeed with
the newer keys but fail with the older ones.

LoadKernel already returns the partition number for the selected kernel.
This change makes it also return the GPT Entry's UniqueGuid, which will
eventually be passed to the kernel itself, so the kernel can determine which
of several possible devices it has booted from. It doesn't know for certain
because the BIOS and the kernel may enumerate the devices in a different
order.

load_kernel_test was failing because it wasn't setting
params->kernel_buffer_size before calling LoadKernel(). This fixes that,
plus adds some checks to LoadKernel so that it will notice bad params if it
happens again.

Do not directly manipulate global structs. Work on the local copy instead.
In firmware-land, globals are a bad idea.

Also renamed verify preamble functions, now that they do not need the
'2' at the end to differentiate them from the now-deleted original
implementation.

This code compiles and installs using a modified ebuild (which needs to be committed after this change).

This makes it much simpler to keep track of what we're doing.
vbutil_key can now wrap both .keyb and .pem keys. It figures out which is
which by trying both and just using the one that works.
vbutil_keyblock and vbutil_kernel now use .vbprivk files for signing.
replace debug() with VBDEBUG(()) in host-side sources, too.
rename PrivateKeyRead to PrivateKeyReadPem
Add real PrivateKeyRead and PrivateKeyWrite for .vbprivk files.

Also, make sure that the regenerated version gets
automatically added to the set of changed files.
Tested by rebuilding the tree and observing the
`git status' output.

This is a mostly NOOP change which modifies the source code
to compile cleanly in the MSVC command line build
environment.
A new makefile is introduced (msc/nmakefile) along with a
README.txt in the same directory explaining how to build
the code in the DOS window. As of this submission the build
is running in a 32 bit environment, the intention is to use
the same makefile for 64 bit builds in the future.
Enabling high compilation warnings level allowed to
identify a couple of bugs in the code which are being fixed.
Not all sources are being compiled in the MSVC environment,
only those in firmware/ and most of those in test/
subdirectories. The benchmark calculations require porting
of the timer facilities and are being postponed.
TEST
Built in DOS and linux environments. Ran unit tests in
linux environment.
