The vboot_api.h doesn't require the BIOS display the ASCII HWID in
a graphical form (ARM U-Boot doesn't know how), so we have to do it
ourselves. This change makes that possible.
Summary of changes:
* bmpblk_font.h defines a structure to map ASCII chars to BMPs
* bmpblk_font utility generates that font structure
* bmpblock format is bumped to version 1.2
- YAML file specifies font to use for $HWID
- make_default_yaml updated to emit the new format
- README updated to describe the difference

I've tested this on ARM, like so:
Inside the chroot, build a U-Boot that uses it:
emerge-tegra2_kaen vboot_reference vboot_reference-firmware
emerge-tegra2_kaen tegra-bct tegra2-public-firmware-fdts \
chromeos-u-boot chromeos-bootimage
Outside chroot, but in src/platform/vboot_reference:
make
<copy ./build/utility/bmpblk_font and ./build/utility/bmpblk_utility to
somewhere in your $PATH>
make clean
cd scripts/newbitmaps/fonts
bmpblk_font --outfile ../images/hwid_fonts.bin outdir/*
cd scripts/newbitmaps/images
make arm
cd out_arm
<edit DEFAULT.yaml>
bmpblk_utility -z 2 -c DEFAULT.yaml arm_bmpblock.bin
<use gbb_utility to replace the bitmaps in the U-Boot image, boot it>
The HWID string is displayed.

This change adds an additional (optional) section to the .yaml file which
can enumerate the names of the locales. If present, these names will be
appended to the end of the bmpblock and the (new) locale_string_offset field
in the BmpBlockHeader will point to it. The names are encoded as a series of
null-terminated ASCII strings. The end of the series is indicated by an
extra null (for example, "en_US\0fr\0\0" names two locales).
The BIOS does not use this information. Factory or OOBE could use it to
select the initiale locale for the BIOS screens from the list of locales
included in the BmpBlock.

With version 1.0, the BIOS displays its screens using composited images, but
we still have to create a new bmp image for every HWID. Version 1.1 lets us
render the ASCII HWID string directly, so the BIOS screens don't need
modification just because the HWID changes.
In the yaml file, we just replace the hwid image with a magic string, like
so:
bmpblock: 1.1
[...]
screens:
en_remove:
- [ 0, 0, remove_bg]
- [256, 534, en_model_text]
- [314, 534, $HWID]
- [192, 479, url]
- [195, 453, en_remove_text]
This change modifies the bmpblk_utility to accept and generate both 1.0 and
1.1 versions. It also updates the supporting scripts (most of which aren't
needed anymore) and adds a new DEFAULT.yaml file which can be used as the
basis for all locales.

LZMA has better compression ratio and is also supported in u-boot already.
ARM BIOS will use LZMA to compress BMP files.

This lets bmpbklk_utility generate BMPBLOCKs with EFIv1-compressed bitmaps.
It also adds the ability to display or unpack BMPBLOCK blobs.
The compression/decompression routines come from the tianocore EDK on
sourceforge and are written in C, so now there's a mix of C and C++, but it
works just fine.
