With this change, init sets a property "init.start" to show the
CLOCK_BOOTTIME time at which init itself started, and for each service
an "init.svc.<name>.start" property to show the CLOCK_BOOTTIME time at
which that service was most recently started.
These times can be used by tools like bootstat to track boot time.
As part of this change, move init over to std::chrono. Also, rather than
make the command-line argument handling more complex, I've switched to
using an environment variable for communication between first- and
second-stage init, and added another environment variable to pass the
start time of the first stage through to the second stage.

When the flag is on, insmod will bypass vermagic and symbol version
checking in the kernel. This is to make it possible to update kernel
without recompiling kernel modules.

If we fail to set a crypto policy on a system-DE directory, this is a
serious and unrecoverable condition; the only way forward is to erase
the entire device. In a future commit we will also allow users the
option of booting again.

Switch insmod from using init_module to finit_module. From
"man finit_module":
The finit_module() system call is like init_module(), but reads the
module to be loaded from the file descriptor fd. It is useful when the
authenticity of a kernel module can be determined from its location in
the file system; in cases where that is possible, the overhead of
using cryptographically signed modules to determine the authenticity
of a module can be avoided.
finit_module is preferred over init_module because it allows LSMs, such
as SELinux, to perform a permission check on kernel module loads based on
the file from which the module is loaded. This functionality is not yet
implemented in the Linux kernel, but is on the SEAndroid TODO list.

Also add remaining user-specific directories and fix linking order.

In current implementation, the mount_all command imports all .rc files
under /{system,vendor,odm}/etc/init/ after mouting filesystems is complete.
There's a need from ODMs to import different .rc files under different boot
modes (e.g., factory mode). Without this support, they will have to fiddle
around the init implementation.
This commit makes mount_all import the .rc files/directories specified
as additional arguments. If no path is given, the original ones are applied
the same way as the current implementation.

When ro.build.shutdown_timeout is set, init will send a SIGTERM signal to
all services on reboot. The normal shutdown process will continue once
all services have exited or after the shutdown timeout
(ro.build.shutdown_timeout).
If ro.build.shutdown_timeout is not set, we assume a 0s timeout.

If the device is corrupted, set up dm-verity in EIO mode instead of
logging mode. This prevents corrupted blocks from being returned to
user space. Note that restart mode is used by default and a warning
will be displayed to the user after corruption is first detected.

Create a Parser class that uses multiple SectionParser interfaces to
handle parsing the different sections of an init rc.
Create an ActionParser and ServiceParser that implement SectionParser
and parse the sections corresponding to Action and Service
classes.
Remove the legacy keyword structure and replace it with std::map's
that map keyword -> (minimum args, maximum args, function pointer) for
Commands and Service Options.
Create an ImportParser that implements SectionParser and handles the
import 'section'.
Clean up the unsafe memory handling of the Action class by using
std::unique_ptr.
