* changes:
init: add fs_mgr_overlayfs_mount_all to FirstStageMount
adb: add overlayfs handling for readonly system filesystems
fs_mgr: get fs_mgr_mount_all to call fs_mgr_overlayfs_mount_all
fs_mgr: add overlayfs handling for squashfs system filesystems
When flashing logical partitions, we read the "super" partition metadata
corresponding to the current slot. We then temporarily create a
device-mapper device for that partition, and immediately destroy the
device after all operations are complete. We do not mount partitions
ahead of time, or keep them mounted, because a fastboot operation may
change the layout of the logical partition table (or change which slot
is current).
Bug: 78793464
Test: fastboot flash a logical partition under "super"

Currently a few getvar handlers will return invalid strings when an
error occurs. This change allows those handlers to instead send a proper
failure message.

EXPECT_DEATH forks behind the scenes, which turns off fdsan, leading to
these tests failing. Instead of duplicating the special
EXPECT_FDSAN_DEATH macro, just move these tests into the bionic fdsan
tests.
Test: none

This change also updates documentation for Parse(Ui|I)nt functions
which recently had a corresponding change applied.

This reverts commit b9d0753d2b.
Reason for revert: Re-land with MacOS workaround.
Test: Build (on Linux) and boot AOSP, with weak symbols enabled and disabled.

The size of `fastbootd` goes down from 64088-byte to 38488-byte
(aosp_taimen-userdebug) after the change.
Bug: 78793464
Test: `m -j installclean && m -j fastbootd`. Check that
$OUT/recovery/root/system/lib64/libadbd.so exists and
$OUT/recovery/root/system/bin/fastbootd depends on that.

adb verity-on setup overlayfs directories, do not skip if verity
feature not configured for device.
adb verity-off teardown overlayfs directories, do not skip if verity
feature not configured for device.
adb remount setup overlayfs directories and mount if possible, and
do so without a reboot if possible.

After fs_mgr_mount_all has added the resources, let
fs_mgr_overlayfs_mount_all to read-only mount overlayfs over the
possible system partitions.

Logistics for adb remount on developer builds for readonly system
partitions using overlayfs to deal with not being able to remount
with read-write.
Conditions are that filesystem is squashfs, read-only, debug build,
kernel supports overlayfs. The default is a valid /cache/overlay/
directory, with .../<mount_point>/upper and .../<mount_point>/work,
associated with each system partition <mount_point>.
Will take the sepolicy of context of lowerdir as rootcontext= option.
Add fs_mgr_overlayfs_mount_all() to recurse through
fs_mgr_read_fstab_default(), and checking against /proc/mounts to
add any acceptable overlayfs mounts. The checking with /proc/mounts
makes sure we do not overlayfs overtop an overlayfs.
Add fs_mgr_overlayfs_setup(const char*, const char* bool*) and
fs_mgr_overlayfs_teardown(const char*, bool*) to respectively setup
or teardown the overlayfs support directories. Return value
includes success and optional supplied change booleans.
