Currently the fsync() inside write_all() may be called multiple times
when performing a command. Move that to the outer loop and call it
only after completing the command.
Also remove the O_SYNC flag when writing a stash.

Only trusted input is passed to parse_range, but check for invalid
input to catch possible problems in transfer lists.

We need to ensure the renamed filename reaches the underlying storage.

This reverts commit b65f0272c860771f2105668accd175be1ed95ae9.
It slows down the update too much on some devices (e.g. increased
from 8 mins to 40 mins to take a full OTA update).

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.

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.

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.
