Make vendor partition a first-class member of the OTA system (for
target_files that contain a VENDOR/ subdirectory).
Build vendor images in a way that is compatible with block-based OTA.
Support updating the vendor partition in both full and incremental,
block and file OTAs. In most cases this is handled by refactoring the
existing code to handle the system partition to handle either, and
then calling it twice.
Currently we don't support incremental OTAs from a target-files
without a VENDOR subdirectory to one with one, or vice versa. To add
or remove a vendor partition a full OTA will need to be done.

When building images, we want to use the file_contexts and fs_config
data contained in the target_files zip, rather than whatever happens
to be in the current client.

img_from_target_files.py just skipps the boot.img and recovery.img since
there is no kernel or recovery.fstab for emulator.

NamedTemporaryFile's aggressive caching behavior can cause an issue
where changes made by another process aren't visible even after the
fseek() below or a flush(). To avoid this, simply open the file
again and read from the fresh version.
This fixes an issue where verity metadata written by append2simg
doesn't become visible to img_from_target_files.

The system partitions has regions that we shouldn't write and can't
depend on the contents of. Adds a new script to generate a map of
these regions (using the sparse image as input), and include the map
in the package zip so it can be used when writing or patching the
system partition.
Also fixes a bug where the wrong SELinux file contexts are used when
generating incrementals.

These scripts already use some post-2.4 features, so let's make it
official: Python 2.7 is needed to run them.

Instead of writing individual files and fixing up their metadata, make
full OTAs contain a system image and simply write it to the block
device.
This is only done for target-files that already contain the recovery
flashing information, older target-files still get a file-based full
OTA.
