Currently block_image_verify() stashes source blocks to /cache and
in some case triggers I/O errors. To avoid this risk, We create
a map from the hash value to the source blocks' range_set. When
executing stash command in verify mode, source range is saved but block
contents aren't stashed. And load_stash could get its value from
either the stashed file from the previous update, or the contents on
the source partition specified by the saved range.

Add and register a function to check if the device has been remounted
since last update during incremental OTA. This function reads block 0
and executes before partition recovery for version >= 4.

To accommodate new changes in N release, such as error correction [1]
and other potential changes to the updater.
[1]: commit 0a7b47397d
Change-Id: I4dd44417d07dd0a31729894628635a0aa1659008
Add block_image_recover function to rewrite corrupted blocks on the
partition. This can be attempted if block_image_verify fails.
Note that we cannot use libfec during block_image_update as it may
overwrite blocks required for error correction. A separate recovery
pass in case the image is corrupted is the only viable option.

We have the last line being empty as a result of
android::base::Split("a\nb\n"), which leads to "missing command"
warnings in the update. Just skip all the empty lines.

Replace C-string with std::string, pointers with references, and
variable-size arrays in struct with std::vector.

There is an integer overflow when the size of system goes beyond the
signed int limits. Hence changing pos to size_t.

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.
