Properties right now can take any format, but that makes it hard to
specify an API for these properties as Treble intends to do.
Therefore this change introduces the idea of property types, described below.
1) 'string' this is the default type and allows any property to be set.
2) 'bool' this allows only boolean values (true|false|1|0)
3) 'int' and 'uint' these allow signed and unsigned integer values
respectively.
4) 'double' this allows floating point numbers with double precision.
5) 'size' this allows for strings matching [0-9]+[gkm].
6) 'enum' this allows only a specific set of space deliminated values
to be set, e.g. 'enum allow these strings' only allows one of 'allow',
'these', or 'strings' to be set.

Currently init expands properties in arguments only when those
commands are run in a subcontext. This creates a hole where
properties that should not be accessible from a given subcontext of
init can be accessed when running a command in the main init
executable (for example `start`).
This change creates a callback in subcontext init that simply expands
and returns arguments back to the main init process, to ensure that
only those properties that a subcontext can access get expanded.

There is a 2s timeout for system property set that currently
uses boot_clock as its clock source. If the system goes to sleep
during a property set, it may erroneously cause the timeout to
be reached as boot_clock increments during sleep. This patch
changes from boot_clock to steady_clock to ignore time spent
asleep when determining this timeout.
bug: 71497234
Test: 1. System service process try to set a system property
with timeout 2s
2. At the same time, the system go into sleep mode more
than 2s
3. System property set will be ok.

Instead of requiring each process to parse the property contexts files
in libc initialization, this change has property_service parse these
files one into a serialized trie, which the property code in libc can
then directly interpret for mapping property names to their associated
SELinux context.

Init currently sets the SELinux context on a mkdir but not on
other operations. This patch modifies it to do so when creating
symlinks, writing to a file, or copying a file.
Test: Built, flashed, and booted. Added fake init entries and
verified that they received the proper SELinux context.

This change explicitly drops all inheritable capabilities (and, by
extension, ambient capabilities) when there are no explicit capabilities
being set by a service and the user is changed. This prevents Android
running in a container from accidentally granting extra capabilities to
services.

in device-tree prior to using it. So raising a FATAL error inside
FirstStageMount when failed to parsing the fstab, in order to expose

Fixed issues related to forking services into new PID + mount
namespaces.
Remounting rootfs recursively as slave when creating a service in new
PID + mount namespaces. This prevents the service from interfering with
mount points in the parent namespace.
Unmount then mount /proc instead of mounting it with MS_REMOUNT, since
MS_REMOUNT is not sufficient to update /proc to the state appropriate
for the new PID namespace. Note that the /proc mount options specified
here are not the same as those used in the default mount namespace. I
kept them consistent with those used in the code prior to this fix.
Test: Used custom sleepd service to test init 'namespace' keyword.
Tested on angler in oreo-dev - I had to add PID namespaces to the
kernel (commit ad82c662).

std::all_of is using std::find_if, which means, if any element the given
