Do not delete snapshots for any reason other than merge-complete or a
cancel request from update_engine. Additionally, create a rollback
indicator file if booting into the source slot, so update_engine can

Avb keys used to verify a partition are stored in the first-stage
ramdisk. However, after /system is mounted, init will chroot into it.
This makes those keys inaccessible for later mounts, e.g., /vendor or
/product.
This change retains avb keys by reading all of them before chroot
into /system.
Note that it is intentional to perform public matching for both
preload_avb_key_blobs and fstab_entry.avb_keys in libfs_avb.
As some keys might only be availble before init chroots into /system,
e.g., /avb/key1 in the first-stage ramdisk, while other keys might
only be available after the chroot, e.g., /system/etc/avb/key2.

CreateLogicalAndSnapshotPartition is used in first-stage init and by
default never blocks (thanks to a timeout set to 0). This causes some
libsnapshot tests to fail, because snapshot devices may be accessed
before there actual creation is complete.
Fix by introducing a timeout_ms argument, set to 0 if unspecified.

Currently, this is only enabled for Virtual A/B devices. When /data uses
F2FS, then proper pinning support must be enabled.
Because /data cannot be mounted in recovery, we can't delete the scratch
image backed by /data while in fastbootd. Instead, we mark it as
disabled in /metadata. The remount command now has an init script that
checks for and removes a disabled scratch partition.

Test: adb remount on V A/B device with patched F2FS
Change-Id: Ifc8720378259654472d3822e97059b6c366f601d
When using partitions backed by /data, for example during a Virtual A/B
merge or "adb remount" on a Virtual A/B device, the userdata block
device is seen as in-use when /data mounts in second-stage init. This
subsequently prevents mount() or e2fsck from working. Metadata-encrypted
devices are not affected, because dm-default-key provides a wrapping
block device that can be used exclusively.
This patch addresses the problem by detecting when userdata has
device-mapper dependencies. If it does, and the device is not
metadata-encrypted, we introduce a dm-linear wrapper around userdata.
It is created on demand, but like logical partitions, it exists until
the device reboots.
