With block-based OTA v2 and v3, it requires stash space on the /cache
partition to back up blocks during an update. We need to ensure that
it doesn't exceed the partition size. Since there might be other files
on /cache as well, we use cache_size * threshold as the maximum allowed
size. The threshold defaults to 0.8, which can be overridden by command
line option '--stash_threshold'.

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().

When generating incremental OTAs, we should use the fstab in the source
build instead of the target one. Similarly for recovery_mount_options.

(cherry picked from commit bebd3cfbf9)
Similar to the assertations in file-based OTA, we perform verification
for block-based OTAs (BBOTAs) after updating a partition, for both of
the incremental and full OTAs. It increases the update time (~20s on
Nexus 6), but will capture unnoticed errors right away.

In ext4 filesystems, some blocks might be changed even being mounted
R/O, such as the superblock (block 0). We need to exclude such blocks
from integrity verification. Plus such blocks should always be
written to the target by copying instead of patching.

In order to work around the zip 2GiB limit, we need to wrap the related
functions in zipfile. Calls to those functions should always be replaced
with calls to the wrappers instead.

Occasionally we need to include full radio image in incremental OTAs.
Adding --full_radio option to support that.
It needs matching changes in the releasetools.py in the target_files
zip, which comes from device/<vendor>/<device>/releasetools.py.

This caught a few bugs/syntax errors (a few character classes were not
escaped properly in regex patterns, some indentation was illegal,
etc).
