For retrofit devices where the super partition is not called "super",
this allows the correct partition to be passed via the kernel
command-line, i.e.:
androidboot.super_partition=system
Since retrofitting is only supported for A/B devices, we assume that
a partition named this way must be slot-suffixed.

For logical partitions, the fstab supplied during
fs_mgr_overlayfs_setup() does not have the correct blk_device and
thus check in fs_mgr_has_shared_blocks() inside
fs_mgr_overlayfs_enabled() will fail to provide the correct status.
Call fs_mgr_update_logical_partition() to fix this up. Side effect
is an API change where fstab can no longer be considered const when
passed into fs_mgr_overlayfs_mount_all() and
fs_mgr_overlayfs_required_devices().
Some additional minor cleanup as well. Move fs_mgr_rm_all() higher
up as-is in the file as it has no dependencies, which will complicate
future changes. Add --help to adb-remount-test.sh unit test script,
improve error handling and checking.

The purpose of this code was to support preserving partitions across a
flashall operation. Since we are not supporting persistent read-write
partitions, this merging code is effectively useless - it is preserving
only partitions that will be deleted.
Additionally, this code does not merge partition group changes, since
doing so accurately is difficult. Partition size changes aren't sent
until after update-super resolves, so a valid re-grouping could be
rejected during update-super if the existing partitions are too big.
This patch removes the update-super merging code until a use case comes
along and we can properly evaluate how it should work.

If a section header such as 'on' or 'service' has an error with it,
the rest of the commands / options are currently reported as errors
since there is no valid parser object to parse them. For example,
service !@#$%%^&*() /system/bin/false
user root
group blah
blah blah
Generates:
init: /system/etc/init/bad.rc: 2: invalid service name '!@#$%%^&*()'
init: /system/etc/init/bad.rc: 3: Invalid section keyword found
init: /system/etc/init/bad.rc: 4: Invalid section keyword found
init: /system/etc/init/bad.rc: 5: Invalid section keyword found
This change suppresses the extraneous 'Invalid section keyword found'
messages.
Test: faulty error messages are suppressed.

The libziparchive public headers that refer to `off64_t` also need the
Mac workaround.
In fastboot, there's a stray `lseek64` but since it's only for offset 0,
any kind of seek is fine.

Partial revert of "init: if vendor_init can read a property, let it be
a trigger too" (b35f827c97).
We made a mistake when we allowed vendor init to action on any vendor
or odm property, since when a new SELinux label is created for a
vendor property, vendor_init does not automatically get read
permissions for it.
Recently, we tried to use read permissions instead of the built-in
list in init, but that broke due to the above mistaken. Since we have
already launched with these permissions as is, we must restore them.

The file-based encryption setup code is being refactored into its own

If an image size changes slightly in between "flashall" and some change

After rebooting to userspace fastboot, the first command issued is
"update-super". If we wound up in the bootloader by accident (as
happened to a few users with a busted vbmeta_system), the resulting
error message will be very misleading ("update-super" will be an
unrecognized command).
Instead, this patch explicitly errors if we did not successfully boot
into fastbootd.

This patch allows the block device table in LpMetadataHeader to contain
additional partitions. MetadataBuilder can now resize partitions such
that are allocated across block devices as needed, however, it attempts
to minimize this by grouping free regions by device.

This change introduces an IPartitionOpener abstraction. Methods that
interact with live metadata, such as ReadMetadata, UpdatePartitionTable,
and FlashPartitionTable, now require an IPartitionOpener object. Its
purpose is dependency injection: it will make these methods much easier
to test when the super partition spans multiple block devices.
All non-test consumers should be using PartitionOpener, and as such,
some helper methods have been added that automatically create one.

This patch removes the alignment, block device size, and starting sector
fields from LpGeometry into a new LpMetadataBlockDevice struct. The
metadata now contains a table of these structs, and the table will have
exactly one entry representing the super partition.
This refactoring will make it easier to have logical partitions span
multiple physical partitions. When that happens, the table will be
allowed to have more than one entry, and the first entry of the table
will be considered the "root" of the super partition.
