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'.

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.

The `fastboot fetch` command is a wrapper around
the fetch protocol. It:
- getvar max-fetch-size
- get the size of the partition
- read the data by chunks, chunk size = max-fetch-size.
The name of the partition is passed directly to the device
(with the usual has-slot magic for flashing etc.) If we support
fetching partitions other than vendor_boot in the future, no change
in the driver is needed.

Some devices, such as the Essential PH-1, don't have an
updated bootloader and the bootloader is appending an extra
underscore.
This patch works around that issue by sanitizing the slot to be
inline with modern expectations.
Offending commit: 42b18a518b
Most of the commit above is not needed because an underscore + slot
is automatically appended when flashing to a partition. Normally, this
would result in something like boot__b instead of boot_b, where b is the
current slot.
Test: flash an image on mata without specifying slot, boots

SnapshotManager::New() is now preferred in recovery. Previously we used
NewForFirstStageMount(), which is technically incorrect as that enables
code paths specifically for first-stage init.
We also explicitly label the snapuserd context, since rootfs in recovery
has unlabelled files.
Finally, we add a timeout to internal calls to
CreateSnapshotsAndLogicalPartitions. Without this, WaitForDevice() calls
will terminate immediately, which breaks VABC given the more complex
device stacking that is created.
