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.

Allow caller to pass additional flags when opening a partition. Obsolete
usage of boolean read, and make previous callers use O_RDONLY instead.
Explicitly OR (O_EXCL | O_CLOEXEC | O_BINARY) to keep existing design
working as is.

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.

With VAB we encourage a smaller super partition, so make sure we delete
"other" slot partitions during flashing. Otherwise, we may not have
enough space in super.

Allow using --force to bypass flashing requirements
from android-info.txt.
We often provide builds to deviceholders who don't have
an exact matching bootloader or radio image and it is
unimportant. Having the option to override is useful.
This shouldn't affect bootloader.img so should never
prevent a device from returning to fastboot in case of
gross error.
Test: Downloaded a build w/ different radio.
Got the following output:
...
Checking 'version-baseband' FAILED
Device version-baseband is 'xyz'.
Update requires 'abc' or '123'.
requirements not met! but proceeding due to --force

Boot v4 is mostly compatible with boot v3, so these minimal changes
should be sufficient.
The newly introduced field of v4, signature_size, is left zero because
this field is only meant to be read by VTS testcases, so the value
doesn't matter for the debugging purposes of boot and flash:raw.

When a user issues `fastboot flash vendor_boot:foo ramdisk.img`, the fastboot driver
fetches the vendor_boot image from the device,
determines if `foo` is a valid vendor ramdisk fragment,
repacks a new vendor boot image, then
flash the vendor boot image back.
This requires vendor boot header V4.
As a convinent alias, `fastboot flash vendor_boot:default ramdisk.img`
flashes the whole vendor ramdisk image. This works on vendor boot header
V3 & 4.
