Change VbExEc functions to take a devidx parameter
This will be used in subsequent CLs to support PD software sync. For
now, only devidx=0 is used.
This changes the external vboot API, so must be checked in at the same
time as changes to the u-boot and depthcharge implementations. For
now, those implementations should simply check if devidx=0 and fail if
it's not.

lib: Add VbExDisplaySetDimension.
For displaying GBB images on panels with different dimension, X86 has VESA mode
and VBIOS to scale automatically but ARM does not have such mode settings. If we
install a larger panel on ARM platforms, current firmware will render the
screens in left-top corner and leave black borders in right-bottom corner.
To render images correctly, vboot library has to send out the expected dimension
(similar to the VESA mode) so display provider can scale or shift images.

vboot: use recovery button as dev mode switch confirmation
We don't allow ENTER from a USB keyboard as the confirmation
in the switch from normal to developer mode.
For devices that have a physical recovery button, we require
a recovery button press instead. For other devices, we
require that ENTER be pressed on the internal keyboard.
This prevents an "evil keyboard" attack in which a USB keyboard
(or other USB device pretending to be a keyboard) sends a
control-D/ENTER sequence shortly after every boot (followed
by more evil keys). In that situation, when users power-on in
recovery mode, they will be forced to dev mode even if it
was not their intention. Further attacks are easy at
that point.
TESTING. On a panther device:
1. powered on with recovery button pressed -> booted in recovery mode
2. pressed control-D on external USB keyboard -> got to ToDev? screen
3. pressed ENTER -> system beeped
4. pressed recovery button -> system rebooted in DEV mode
... all as expected
Also:
1. powered on with recovery button pressed and HELD recovery button
2. pressed control-D -> system beeped

Get rid of some crufty macros.
These were macros that were never used, or that were only set to one thing and
could be substituted up front.
I left in code guarded by the HAVE_ENDIAN_H and HAVE_LITTLE_ENDIAN macros even
though those are never defined because they guard a reportedly significantly
faster implementation of some functionality, at least according to a comment
in the source. It would be a good idea to enable that code path and see if it
really does make a big difference before removing it entirely.

Change VbExEcGetExpectedRW so that vboot picks an ec image instead of U-Boot.
This changes the signature of the function above so that it takes an additional
parameter that specifies which EC image vboot wants. This is better than making
U-Boot decide because U-Boot doesn't really keep track of which version it is
(it peeks at internal vboot data) and vboot does.
Also, some consts were removed from the image pointer pointer. The pointer
itself will be changed in the body of the function to tell vboot where the EC
has been loaded, and the contents of the buffer will be changed because U-Boot
will have to actually load the EC there.
BUG=chrome-os-partner:11148
TEST=Built vboot_reference, vboot_reference-firmware, chromeos-u-boot, and
chromeos-bootimage for Daisy and Link and saw them complete successfully with
and without the signature for U-Boot's version of this function being updated.
That works because the function isn't actually being used yet.

VbExBeep() now returns VbError_t instead of void
This enables us to support playing sounds in the background if the BIOS
allows it, so we don't have to block while beeping is happening. The new
declaration is:
VbError_t VbExBeep(uint32_t msec, uint32_t frequency);
If the audio codec can run in the background, then:
zero frequency means OFF, non-zero frequency means ON
zero msec means return immediately, non-zero msec means delay (and
then OFF if needed)
else:
non-zero msec and non-zero frequency means ON, delay, OFF, return
zero msec or zero frequency means do nothing and return immediately
The return value is used by the caller to determine the capabilities. The
implementation should always do the best it can if it cannot fully support
all features - for example, beeping at a fixed frequency if frequency
support is not available. At a minimum, it must delay for the specified
non-zero duration.
Currently, VbExBeep() is called only when displaying the dev-mode screen.
BUG=none
TEST=manual
I've tested on x86 and ARM, all timeouts and noises work as before.
Note that ARM and coreboot will require a corresponding change to their
VbExBeep() implementations, which will have to be handled with separate,
simultaneous CLs.

Decompress images in vboot wrapper, not in BIOS.
The vboot library needs to decompress the images so that it can handle those
that are special cases (like rendering the HWID). This means that 1) it
needs access to the BIOS' native decompression routine, and 2) that
VbExDisplayImage() only needs to handle the uncompressed native-format image
and doesn't need to know about how the image is packed in the GBB.
BUG=chromium-os:19134
TEST=manual
This requires a change to vboot_api.h, which requires a (simultaneous)
matching change to the BIOS, at least for U-Boot, which builds separately.
I've made that change and run the "vbexport_test display" command from the
modified U-Boot, but that also requires a change to the way U-Boot is built
so that I can get at the U-Boot commandline.
