Fastboot format fails to wipe any partition that doesn't at least return
"raw" partition type. Also both android.hardware.fastboot@1.0-impl.pixel
and android.hardware.fastboot@1.1-impl-mock return FileSystemType::RAW
so I assume this is fine.

This ensures that the dynamic "scratch" partition is removed when doing
a flashall operation.
If "scratch" is on /data, disable the partition. Add IsImageDisabled to
ImageManager so EnsureScratchMapped can skip mapping it. Also, fix
"scratch" not getting unmapped if on /data.

The vbmeta partition might have additional prefix
(e.g., guest_vbmeta_a) on some virtual machine
environment. Allowing rewriting the disable-verity/
disable-verification bits in the vbmeta image upon
flash under such use case.

Similar to GKI boot.img, init_boot.img is released as a specific size
and should be able to be flashed into partitions that have different
sizes. So the AVB footer is moved from the end of the init_boot.img to
the end of the partition in the case that the partition is larger than
the image.

Device might return I/O error instead of FAIL message
if command send to device is too large.
Since maximum command size in fastboto protocol is 64 bytes.
The device might only try to read 64 bytes for the bulk transfer,
sending data more than that might result in USB I/O error.
Do proper handler for that in fuzzy_fastboot and reset the USB
if I/O error encounter during the Comman.dTooLarge test

Direct writes for partition flashing significantly increase performance.
Use O_DIRECT flag when opening partition for flashing. Additionally use
a 4096b aligned buffer which is required for O_DIRECT.
Switch from using 8MB write buffer to 1MB write buffer, as the extra
allocation has no performance impact.

There is an unclear error message if we run
`fastboot --disable-verification flash boot boot.img` on a
AVB-disabled device without a /vbmeta partition.
Error message:
terminating with uncaught exception of type std::out_of_range: basic_string
Aborted
This is because the buf->fd of the loaded boot.img is not reset,
before returning from function copy_boot_avb_footer().
Also reset some changes in copy_boot_avb_footer() from commit
If83f785e235569ee8ef0de2b37f11dbd2a9a71f4, to prevent the
unnecessary read of the boot vbmeta if no need to copy the
boot image avb footer.
