file_contexts (specified by SELINUX_FC) is needed both when building
and (re)packaging. We used to use the copy in out/ when building, and
looked for the copy in BOOT/RAMDISK/ when packaging from target_files
zip. With system_root_image enabled, the file_contexts needed for
building and packaging might be different from the one on device. So
we explicitly pack the file as META/file_contexts in target_files zip.
Also refactor out the overriding of selinux_fc property into
common.LoadInfoDict().

It's not necessary to call block_image_verify for the most common
case where we attempt an update for the first time and the target
partition has expected contents. It is sufficient to confirm that
the target partition is intact.
Computing a hash is much faster than simulating the update, which
means this change should make the update speed for v3 much closer
to v2 for the common case. If the update was interrupted, this is
going to make resuming somewhat slower, of course. Hopefully this
should be rather rare.

(cherry picked from commit 72d90eb189)
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.

likely explanation) and the need to flash to get OTAs working again.

Currently, the "img" zip files generated by the build system lack the
script and data needed to rewrite the recovery partition, while the
"ota" zip files do (when installed).
In order to move towards block-based OTAs, we want the result of
flashing an image and the result of installing the corresponding OTA
package to be identical.
Generate the recovery-from-boot patch and install script as part of
the process of building the target-files. This requires breaking the
code to generate that out of ota_from_target_files into its own tool
that we can run from the Makefile. (ota_from_target_files can still
do this, so it continues to work with older target-files.)

Move the image sizes into a more generic key-value file. Make them
optional. Add additional key/value pairs describing what kind of
filesystem the device uses. Pass new fs-type-related arguments in
edify scripts when mounting and reformatting partitions.
Don't include all the init.*.rc files from the regular system in
recovery -- they aren't needed, and break recovery on some devices.

This makes them accessible from device-specific extensions (so they
can be used to send radio images as binary patches, for instance).

Setting LOCAL_CERTIFICATE to "EXTERNAL" now marks an apk (either a
prebuilt or otherwise) as needing the default test key within the
system, but one that should be signed after the target_files is
produced but before sign_target_files_apks does the rest of the
signing. (We use this to ship apps on the system that are signed by
third parties, like Facebook.)
The check_target_files_signatures determines what key was used to sign
every .apk in a given target_files. It can compare that signature to
that of another target_files (eg, the previous release for that
device) and flag any problems such as .apks signed with a different
key.
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).
When unzipping a target-files which has been signed with OTA key
replacement, you'll get "overwrite this file?" prompts because the key
files appear in the zip files twice. Suppress these prompts.
Many developer phone products don't define PRODUCT_OTA_PUBLIC_KEYS, so
add a default key.
This change doesn't affect device code.

* commit 'b6153173952895441e55d0ff6be332bb7c7605e2':
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.
If we fail to load the device-specific releasetools module (ie, if -s
is specified but the file is missing), issue an error message but
continue without any device-specific code.
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.
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).
The ota and img building scripts contained some hardcoded 'linux-x86'
paths. Remove and replace with a slightly redefined -p option.
Modify Makefile to pass correct -p when building.
Some devices define a BOARD_KERNEL_BASE argument which must be given
as an argument to mkbootimg when building a bootable image. Store the
value of this var (if any) in the target-files zip and use it when
building images.
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.
Use minigzip (from the zlib distribution, built in the android tree)
to compress images rather than the system install of gzip. This will
let us send useful patches for images since we can make zlib available
in the applypatch program.
Allow the user to set ANDROID_PW_FILE to the name of a file for
storing password keys. When the tools need additional passwords, they
will rewrite this file and invoke the user's editor for the new
passwords to be added. This allows passwords to be reused across
invocations of the signing tools, without making the user reenter them
every time.
Paranoid users can use a file stored in a ramdisk, or not use this
feature at all (the code will prompt for passwords in the ordinary way
when ANDROID_PW_FILE is not set).
The build system now (in donut) produces builds that use the testkey
cert for OTA package verification. Change the app-signing script to
also optionally substitute the "real" cert in both the recovery and
system images. Also fix bug where the build fingerprint and
description were not getting properly updated in the recovery
partition.
