f58b009b7b Disable warning which is not detecting problems. 
A clang update enabled -Wreorder-init-list by default. Since it doesn't
provide any benefit to the debuggerd code, disable the warning.

244e581a31 fs_mgr: Use /proc/mounts to check if /cache is mounted 
The fstab provided by the user/caller might not be the default fstab,
which might not include the /cache mount entry. We should just use the
procfs mount info to determine if /cache is currently mounted.

bcae6b5e60 libsnapshot_cow: Prepare device to boot from pre-created snapshots 
Two new API's have been added:

1: BootFromSnapshotsWithoutSlotSwitch: This will create a new marker
which indicates first-stage init to mount the partitions off snapshots.

We need this marker as during boot, there are couple of places during
mounting snapshots wherein the marker is used. However, there is no
change in the existing I/O path related to OTA.

2: PrepareDeviceToBootWithoutSnapshot: This will delete the marker so
that subsequent reboot will not have the partitions mounted without the
snapshots.

VTS tests covers both these API's. Additionally, when these
markers are present, new OTA's cannot be installed. All these
are covered in VTS tests.

===========================================================

snapshotctl: General flow to apply and revert pre-created snapshots

1: To install the pre-created snapshots:

$snapshotctl map-snapshots <directory path containing snapshots patches>

Now the device is ready to boot from snapshots.

2: After device reboots, partitions are mounted off the snapshots. There
   is no snapshot-merge.

3: In order to go back to previous build:

$snapshotctl revert-snapshots

Now the device is ready to boot from base build.

4: After device reboots back to previous build, all the snapshot states
   and COW images are removed.

============================================

Additional commands:

To delete the pre-created snapshots:

$snapshotctl delete-snapshots

======================================

Tested it on Pixel 6 Pro between two builds which are ~24 hours apart.

1: Creating snapshots on a linux-host - ~4-6 seconds
2: Applying pre-created snapshots - ~10-15 seconds (includes intermediate
   transfer of patches to the device). This depends on the size of snapshot patches.
3: Device reboot - ~12-14 seconds.

Bug: 299011882
Test: 1: Apply pre-created snapshots
2: Reboot device: Verify new build
3: Apply OTA when partitions are mounted of snapshots and verify OTA
   fails.
3: Revert-snapshot and reboot.
4: Verify device goes back to base build.

Full OTA on Pixel. vts_libsnapshot_test

adaf33026a Drop String8::std_string 
This method was preserved under assumption it would be baked into many
prebuilts, but since it's inline, there should be no linkage to libutils
- thus, should be safe to remove anyway.
