Currently, system properties are passed via the environment
variable ANDROID_PROPERTY_WORKSPACE and a file descriptor passed
from parent to child. This is insecure for setuid executables,
as the environment variable can be changed by the caller.
Modify system property handling so that we get the properties
from a root owned properties file, rather than using an
environment variable.

Also, clean up how we initialize the ro.xx properties and process
the kernel command line.

Fix for bug 3415286. The persistent properties are normally read early
in the boot process after /data is mounted. However, for an encrypted
system, at that point /data is a tmpfs ramdisk. This change adds a new
command to init (load_persist_props) to read the persistent properties,
and adds an action to init.rc to load the persistent properties. This
action is triggered by setting a property in vold, but that's in a
different CL.
