This change adds a "verify" fs_mgr flag specifying that
the device in question should be verified.
Devices marked with this flag are expected to have a
footer immediately after their data containing all
the information needed to set up a verity instance.

We have several partitions with underscores in their names
which would not be properly linked in:
/dev/block/platform/msm_sdcc.1/by-name/
With this change more characters (_-.) are allowed in
partition name links. Also, any other character is
replaced with '_' so the resulting link names have the
same length as the partition name.

Create a new "androidboot.selinux" option, to control how userspace
handles SELinux. This kernel command line can have three options:
* disabled
* permissive
* enforcing
"disabled" completely disables userspace support for SELinux. No
policy is ever loaded, nor is the SELinux filesystem /sys/fs/selinux
ever mounted.
"permissive" loads the SELinux policy, but puts SELinux into
permissive mode. SELinux policy violations are logged, but not rejected.
"enforcing", the default, loads the SELinux policy, and places
SELinux into enforcing mode. Policy violations are rejected.
This change addresses post review comments for change

When init starts up, immediately put SELinux into enforcing mode.
This is currently a no-op. We currently have everything in the
unconfined domain, so this should not break anything.
(if it does, I'll roll it back immediately)
If the kernel doesn't have SELinux support compiled in, then
don't try loading a policy and continue without SELinux protections.

init: move initial property area allocation into bionic
property_service: make /dev/__properties__ readable
bionic's __system_property_add() now expands the property area as needed
by mapping in more pages. Rather than duplicate the mapping code, move
it inside bionic and have bionic's __system_property_area_init() set up
the first page.

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.
Make the /dev/__properties__ file accessible, so an app can
get properties directly from the file, rather than relying on
environment variables.
Preserve the environment variable for compatibility with pre-existing
apps.

The previous patch "init: verify size of property buffers passed
to property_get" incorrectly modified one of the callers,
resulting in ro.serialno, ro.bootmode, ro.baseband, and
ro.bootloader always being set to their default values.

Move the system property writer implementation into bionic to keep

Property triggers may cause an action to be queued twice, resulting
in a loop in the action queue. Keep actions that are not on the queue
in the list_empty state (act->qlist->next == act->qlist), and only
add them to the list if they are in that state.
