In case of non-secure builds (eng variant) fs_mgr_setup_verity() skips
verity checks regardless of fstab options. This is slightly different
than 'adb disable-verity' where it would first read the verity metadata
to check if verity is disabled.
So, this change adds a new return value of FS_MGR_SETUP_VERITY_SKIPPED
instead of piggy backing on the FS_MGR_SETUP_VERITY_DISABLED.

First stage mount in init currently attempts to regenerate uevents for
specific devices to create the corresponding dev nodes. However, this
is racy as first stage mount happens early in the boot process and
it's possible that some of these devices have not yet been created by
the kernel.
To fix this issue, init will poll on the uevent socket for up to 10
seconds waiting for the kernel to create the required device. It will
return false and panic if this 10 second timeout passes.
Note that the same uevent socket is used in the uevent regeneration
and the polling code, so there is no race if the device is created
after the uevent regeneration and before polling starts; the first
poll will pick up the device.

In order to create symlinks for USB and block devices, the path for
their parent platform device must be known.
Previously, ueventd would save each platform device that it encounters
to a list and query this list when creating the symlinks. That,
however, is racy because the uevent socket does not differentiate
uevents from RegenerateUevents() and uevents sent by the kernel when
probing a device first the first time. The below scenario is the
faulty case:
1) Kernel probes parent platform device for a block device
2) ueventd calls RegenerateUevents() and starts processing uevents
3) Kernel probes block device and sends its uevents
4) ueventd picks up the block device uevent during its uevent processing,
without yet regenerating the platform device uevent, causing improper
symlinks to be created.
This change stops storing the platform devices in a list, and instead
traverses up the directory structure for each USB or block device
until it reaches a platform device, defined as one whose subsystem is
the platform bus. This fixes the race and simplifies the ueventd
code.

ueventd already does restorecon() for /sys/{block,class,devices}, so
instead of duplicating this effort with init, move the restorecon()
that init does for all of /sys to ueventd.

restorecon_recursive may take a long time if there are a lot of files on
the volume. This can trigger a watchdog timeout in any process that
tries to set a property while it is running. Fix this by running
restorecon_recursive in its own process.

Commit 795267d4c7 ("Removed cpusets/schedboost build time dependency.")
turned the cpusets and schedtune options into runtime
decisions.
However the kernel option which is mentioned in the
code comment (CONFIG_SCHEDTUNE) is very misleading
as it doesn't exist (CONFIG_SCHED_TUNE does exist)
and it doesn't describe the real functionality of
the method. schedboost_enabled() will still return
false if CONFIG_SCHED_TUNE is set in the kernel but
CONFIG_CGROUP_SCHEDTUNE is not.
So to clarify this, we need to change the comment
to reflect that CONFIG_CGROUP_SCHEDTUNE, which depends
on CONFIG_SCHED_TUNE, is required.

Kernel can use vsyscall for system calls. The vsyscall implementation in
the kernel gives one more depth in the backtrace. It leads to failures
on CrasherTest. This CL makes tests find a system call frame not only in
