Problem:
ueventd: coldboot took too much time
Solution:
1.The parallel restorecon dirs can be configured in ueventd.rc
2.Add 'parallel_restorecon_dir' keywords
parallel_restorecon_dir <directory>
Verify:

Our CI is failing because the host machine is using mawk instead of gawk.
mawk v1.3.3 cannot parse regex such as '/[/]/', while mawk v1.3.4 and
gawk can.
Change regex of '[/]' to '\/' so that our test script is as backward
compatible as possible.

Parse the "lowerdir=" option from fs mount flags instead of fs_mgr flags
for consistency.
Before:
none /mnt/product/test1 overlay ro lowerdir=/1:/2,first_stage_mount

This can be useful in case when a device mapper device can't be deleted
straight away, and instead delete needs to be enqueued until last
reference to the device is closed.

Rename fs_mgr_overlayfs_mount_fstab_entry() to
fs_mgr_mount_overlayfs_fstab_entry() and move it out of
fs_mgr_overlayfs.cpp to make it available for user builds.
Add checks to unsure overlayfs mount point doesn't contain symbolic
link or /../.
Check the mount point with an allowlist if user build. The mount point
should either be /vendor, /product ... or their submounts, or strict
submounts of /mnt/vendor and /mnt/product.

Refactor skip_administrative_mounts so that it filters by device name,
mount point and filesystem type. (Was filtering by device name and mount
point.)
We need this because pseudo filesystems such as tmpfs and overlayfs can
have free-formed device name:
blah /mnt/mnt_point overlay ro,lowerdir=...
However the filesystem type (third field of /proc/mounts) must be
reflecting the actual filesystem, so to robustly filter out
administrative filesystems, we have to check the filesystem type field.

adb-remount-test.sh would fail if a overlayfs named "overlay" is mounted
in first_stage_init via fs_mgr_overlayfs_mount_fstab_entry():
[ FAILED ] overlay takeover unexpected at this phase
Prepend the source device name with "overlay-", so that the overlayfs
mounted by fs_mgr_overlayfs_mount_fstab_entry() mustn't be named
"overlay".

Fixes a compiler warning for implicit conversion changes from signed
to unsigned which surfaced when refactoring native input libraries.
Add an explicit cast to avoid adding -Wno-sign-conversion compile
flags.

* Add logs.
* Append "override_creds=off" overlayfs mount flag only if
fs_mgr_overlayfs_valid() returns kOverrideCredsRequired.
Pre-4.6 kernels or kernels without the override_creds patch don't
need or don't recognize the override_creds mount flag.
(Background: I832c8ca3fce0269bdef4ce988541adb7ba9662ed)
* mkdir(mount_point) before mount() to ensure the mount point exists.
This could happen if the mount point is in a tmpfs, such as /mnt.

GetDmVerityDevices() should filter out overlayfs fstab entries in the

pseudo device names.

Header response from daemon is sent once at the
beginning of the payload. This is a corner case
when the IO request can get broken into multiple chunks
if the IO is un-aligned.
Additionally, add error checks in the IO path
to validate sector information when the read
requests are merged.

Test: Simulate an IO request to forcefully break the IO
response into multiple chunks and verify the correctness.

It's possible that CONFIG_ZRAM_WRITEBACK is y,
but userspace doesn't set the /sys/block/zram0/backing_dev,
so its value is 'none'.
It's the same with "CONFIG_ZRAM_WRITEBACK is not set".

The external firmware handler always has root group privileges because
it is forked/executed without setgid() by ueventd which has root
privileges. This patch calls setgid() with group ID specified in
ueventd.rc before execv().

ART wants to optimize the time when the profile information
is saved for an app. To do so, it needs access to both, the current
profile, and the reference profile. This will allow ART to access
the ref profiles, which previously was not needed.
