Make the recovery image be the first thing installed in system/ in the
OTA package, so it will get installed even if the system partition
fills during OTA installation.
Store the location of the releasetools extensions in the target-files
zip, and make ota_from_target_files use that stored location by
default (though it can still be overridden with -s if desired).
Change ota_from_target_files to compute binary patches for all the
changed files in the OTA package in parallel. On a recent test build
this cuts incremental construction time roughly in half (6 min to 2
min 40 sec).
Make the OTA progress bar advance a bit more smoothly by reallocating
how much is dedicated to various phases of incremental OTA
installation, based on some crude measurements of how long each phase
takes.
imgdiff now understands the zip file format and can produce smaller
patches by doing the patching in uncompressed space. Start taking
advantage of this for .zip, .apk, and .jar files.

use the max image sizes from the target files zip
For some time now the build system has included all the max image
sizes in a file in the META directory. Use these instead of needing
to parse the BoardConfig.mk file for the device at the time of
building an image or OTA package.
Instead of storing the whole recovery image in system in order to
flash it on first boot, we instead use an imgdiff patch from the boot
image to create the recovery image. This is substantially smaller
since it effectively only stores the recovery binary and UI images
(the kernel and the init binary are identical to that of the boot
image).
This change modifies the OTA-building script to create and install
these patches, and changes the calculation of the system image size in
the Makefile to reflect the new scheme.
Interpret a "*" in the "require version-bootloader" line as "don't
require any specific bootloader". Sholes OTAs include the bootloader
and the main system in the same package.

in auto mode, generate both edify and amend scripts for full OTAs
If the source target-files zip omits files needed to build the
recovery and/or boot images, leave them out instead of dying with an
error. This lets build like "generic-userdebug" work.

don't fail if no required bootloaders are defined
Generic targets don't have a list of defined bootloaders. Instead of
failing to build an OTA package, just omit the constraint.
Fix bad references to ExternalError.
Replace the installation of the "radio image", which is an
HTC-specific notion, with calls to device-specific python modules that
can add whatever additional OTA script commands are necessary. Add
the -s flag to specify the location of the device-specific script
(replacing the unused -s flag in sign_target_files_apks).
Split the details of generating script syntax into a generator class:
one for amend (whose output should be equivalent to the current
output), and one for edify.
Fix 'otatools' build rule to build imgdiff.
Make the following things optional:
- kernel command lines for bootable images
- radio images
- bootloader assertions
These are not all (yet?) defined for some new devices.
In python 2.5 and earlier, ZipFile.writestr(filename, data) results in
the file being added to the archive with permissions 000. (See
http://svn.python.org/view?view=rev&revision=65235.) Work around this
by creating a ZipInfo object and setting the permissions explicitly.
Modify applypatch to be able to write MTD partitions as well as read
them. Make applypatch save a backup copy of the contents of an MTD
partition it reads in cache, to be used in case an update is
interrupted while writing back to MTD. Modify OTA package creation
script to send boot image updates in patch form.
Allow an MTD partition so serve as a source "file" in applypatch,
using a magically-formatted 'filename' that specifies the partition
name, size of data to read, and expected hash. Build incremental OTAs
that update the recovery image via a patch.
Allow applypatch to use different filenames for the source and target.
(Using the same filename is still fine; in fact the target filename
can be specified as "-" to mean "same as the source file.) This will
allow us to still use diffs in the case of files being renamed, and
will allow us to use diffs for the boot and recovery images.
