Test: builds, boots successfully and external storage remains
an sdcardfs mount by default and works correctly
Test: cat /proc/1/mountinfo is unchanged

Linker ignores link configuration if either namespace is not valid.
However there was a link configuration from postinstall section which
target link namespace does not exist. Also, there was no binary within
postinstall from hwasan build (checked with bonito), so there may be no
usage for this section now. Removing this line for better human
readability, and behavior of the linker would be same as before.
Test: m -j && tested from cuttlefish

This CL implements some of the libsnapshot internals necessary to work
with update_engine. In particular it implements snapshot and update
state, as well as creating and mapping snapshot devices. It does not
implement anything related to merging, nor does it implement the full
update_engine flow.
Update state is stored in /metadata/ota/state. To synchronize callers of
libsnapshot, we always flock() this file at the top of public functions
in SnapshotManager. Internal functions are only called while the lock is
held, and a "LockedFile" guard object is always passed through to
indicate proof-of-lock.
Low-level functions, such as snapshot management, have been moved to
private methods. Higher-level methods designed for update_engine will
ultimately call into these.
This CL also adds some functional tests for SnapshotManager. Test state
is stored in /metadata/ota/test to avoid conflicts with the rest of the
system.

Linkerconfig requires more libraries txt files to get library list
related variable values. To make this available from runtime, those
should be added as build target and included in system image.

Recently Android build team changed environment to use prebuilt toybox
binaries for common tools (aosp/852849). However, as toybox xargs does
not support -I option, update_and_install_ld_config.mk started to fail
filtering out private vndk libraries from the list. To resolve this,
xargs usages are replaced with other shell command (read).

/metadata/ota will store the update state ("none", "applying",
"booting", "merging") for each dynamic partition. The data will be
managed by libsnapshot, whose primary consumer will be update_engine
but will also be available to recovery/fastbootd.

Test: /metadata/ota exists

system_suspend need to be an early_hal as it's required before storage
encryption can get unlock on FDE devices.
/sys/power/wake_lock is a dependency of system_suspend (only in Q and
earlier). Permissions on this file need to be set early enough.

This reverts commit 997a2d93d7.
Reason for revert: This revert is needed, just also need some selinux rules for changes to the script that runs if this folder is present.
