The erase command we insert at the top for full OTAs was getting
inserted in the wrong place for version 2.

Generate version 2 of the block_image_update transfer list format.
This improves patch size by a different strategy for dealing with
out-of-order transfers. If transfer A must be done before transfer B
due to B overwriting A's source but we want to do B before A, we
resolve the conflict by:
- before B is executed, we save ("stash") the overlapping region (ie
the blocks B will overwrite that A wants to read)
- when A is executed, it will read those parts of source data from
the stash rather than from the image.
This reverses the ordering constraint; with these additions now B
*must* go before A. The implementation of the stash is left up to the
code that executes the transfer list to apply the patch; it could hold
stashed data in RAM or on a scratch disk such as /cache, if available.
The code retains the ability to build a version 1 block image patch;
it's needed for processing older target-files.

There may be cases where there is an OEM partition
but it has no effect on the OTA itself. In these
cases, ignore an empty value from the misc_info.txt

No need to pass in the HTML tags to start and end the list, since
we do the same thing everywhere, and it wasn't very complete anyways.

Add the "Included in documentation due to annotations..." text for
fields, enum constants, and pretty much everything with a description.
Added annotation text to eh classes.cs file used to generate the
class list page.

When generating incrementals for the system and vendor partitions,
check the first block (which contains the superblock) of the partition
to see if it's what we expect. If this check fails, give an explicit
log message about the partition having been remounted R/W (the most
likely explanation) and the need to flash to get OTAs working again.

Made the foreground of the "included in docs by annotation..." orange,
the same color used in the header of the docs page. This text is inserted
when the showAnnotations flag is used with doclava

Move BlockDifference into common and make its script generation code
more complete, so that it can be use by releasetools.py to do diffs on
baseband images.

Now that we're building and saving images in the target_files at build
time, we should use those images instead of rebuilding them.

This ensures that when the verity key is rotated to a release key
both the boot and recovery images will be correctly signed. It does
mean that they will both be signed with the same key for now, but
as that doesn't change the threat model separating them is just a
distant nice-to-have.

The AOSP bootimage format allows the use of a second stage image
however the BuildBootableImage function does not allows the "second"
optional argument. This patch adds the support of this argument.

make_ext4fs can now output a file listing the blocks used for each
file in the image. Request this file and save it in the target_files;
it will be used for future improvements to block OTAs.

When making bsdiff/imgdiff patches, give up after 5 minutes. (On
certain large files it can take hours to build a patch, if it ever
even completes.)

Block incremental OTA generation can currently fail on some
target-files pairs. Fall back to generating a full OTA so that the
script succeeds rather than failing.

Store sparse images in the target-files, and use those (when they're
available) for building block OTAs.
- New script add_img_to_target_files is added to make the images and
add them to the IMAGES/ subdir in the target-files. It gets run
from the Makefile when building a target-files.
- img_from_target_files becomes mostly vestigial: it creates the
img.zip by just copying the images out of the target-files. (It
still knows how to build images for use on older target-files.)
- ota_from_target_files uses images from the target-files in
preference to rebuilding images from the source files.
- sign_apk_target_files builds images and includes them in its output
target files (even if the input target-files didn't have them).

Atree used to output files without escaping the filenames. This resulted
in breaks for incremental builds when filenames contained '$' symbol.
The change fixes this by escaping the filename properly.

Zopfli provides compression roughly 5% better than zlib, while remaining
completely compatible with zlib decoders. This patch adds a "-z" option
to zipalign, recompressing all compressed files within the zip archive.
