A RangeSet has half-closed half-open bounds. For example, "3,5" contains
blocks 3 and 4. So "3,5" and "5,7" are actually not overlapped.

Due to observed BLKDISCARD flakiness, overwrite blocks that we want
to discard with zeros first to avoid later issues with dm-verity if
BLKDISCARD is not successful.

In the block updater, if BLKDISCARD fails, the error is silently
ignored and some of the blocks may not be erased. This means the
target partition will have inconsistent contents.
If the ioctl fails, return an error and abort the update.

When automatically stashing overlapping blocks, should the stash
file already exist due to an explicit stash command, it's not safe
to remove the stash file after the command has completed.
Note that it is safe to assume that the stash file will remain in
place during the execution of the next command, so we don't have
take other measures to preserve overlapping blocks.
The stash file itself will be removed by a free command when it's
no longer needed.

that function will live on as a utility even after we move the

Add support for transfer list version 3, which allows us to
verify the status of each command and resume an interrupted
block based OTA update. Notes on the changes:
- Move the previous BlockImageUpdateFn to a shorter and
reusable PerformBlockImageUpdate, which can be used also
in BlockImageVerifyFn for verification.
- Split individual transfer list commands into separate
functions with unified parameters for clarity, and use
a hash table to locate them during execution.
- Move common block reading and writing to ReadBlocks and
WriteBlocks to reduce code duplication, and rename the
readblock and writeblock to less confusing read_all and
write_all.
The coding style of the new functions follows the existing
style in the updater/edify code.

When building for 32p, we need to be explicit that we wish to build
the 32bit version of the binaries that will be placed in the recovery
image. The recovery image doesn't actually care... but if we are not
explicit in this, the makefiles will ask for the 64bit binaries but the
Android.mk for the binaries will supply the 32bit images (causing the
build to fail).

At the end of the OTA script, we walk through /system, updating
all the permissions on the filesystem, including the UID, GID,
standard UNIX permissions, capabilities, and SELinux labels.
In the case of a symbolic link, however, we want to skip most of
those operations. The UID, GID, UNIX permissions, and capabilities
don't meaningfully apply to symbolic links.
However, that's not true with SELinux labels. The SELinux label on
a symbolic link is important. We need to make sure the label on the
symbolic link is always updated, even if none of the other attributes
are updated.
This change unconditionally updates the SELinux label on the symbolic
link itself. lsetfilecon() is used, so that the link itself is updated,
not what it's pointing to.
In addition, drop the ENOTSUP special case. SELinux has been a
requirement since Android 4.4. Running without filesystem extended
attributes is no longer supported, and we shouldn't even try to handle
non-SELinux updates anymore. (Note: this could be problematic if
these scripts are ever used to produce OTA images for 4.2 devices)

In version 2 of block image diffs, we support a new command to load
data from the image and store it in the "stash table" and then
subsequently use entries in the stash table to fill in missing bits of
source data we're not allowed to read when doing move/bsdiff/imgdiff
commands.
This leads to smaller update packages because we can break cycles in
the ordering of how pieces are updated by storing data away and using
it later, rather than not using the data as input to the patch system
at all. This comes at the cost of the RAM or scratch disk needed to
store the data.
The implementation is backwards compatible; it can still handle the
existing version 1 of the transfer file format.

Otherwise, overflow problems can occur with images larger than
2G since the offsets will overflow a 32-bit off_t.

The computation of file offsets was overflowing for partitions larger
than 2 GB. The parsing of the transfer file could fail at the end if
the data happened to not be properly null-terminated.

Sometimes renames will move a file into a directory
that does not yet exist. This will create the
parent directories, using the same symlink logic,
to ensure that there is a valid destination.

- for the install "format" command.
Note: crypto data in "footer" with a default/negative length
is not supported, unlike with "ext4".

The default recovery UI will reboot the device when the power key is
pressed 7 times in a row, regardless of what recovery is doing.
Disable this feature during package installation, to minimize the
chance of corrupting the device due to a mid-install reboot. (Debug
packages can explicitly request that the feature be reenabled.)
