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
b710ed21de .

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.

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.

Move the responsibility for rebooting the system from the
reboot command to init. Init is in a better position to take
actions to bring the system down cleanly, including making sure
filesystems are mounted read-only.
The only UIDs which can perform an init triggered reboot are
root, system, and shell.
Modify the reboot command so that it calls into init to perform
the reboot. The reboot command no longer requires CAP_SYS_BOOT.
Remove the -n reboot option and code which supports it. Anyone needing
to do an unclean shutdown can just do a 'echo c > /proc/sysrq-trigger'.

Currently, the output of e2fsck is not saved, and we have no insight
into how many errors e2fsck is finding and fixing. Using the new
abbreviated logging feature in liblogwrap, up to the first 100 lines,
and last 4K bytes of the output of e2fsck is captured by fs_mgr, and
added to the kernel log.
Usually, the filesystem will be clean, and this will only add a few
lines to the kernel log on boot, but when things go wrong, it should
save enough to indicate what the problem is, without potentially
filling the kernel log with only e2fsck output if the filesystem is
really corrupted.

As it turns out, no, 64K is not enough. A device provisioning
tool was generating many uevents as it manipulated the GPT,
causing events near the end of the process (including events
as a result of the final BLKRRPART ioctl()) to get lost.
It's not clear what the best value for this should be, but
increasing to 256K fixed the problem in this case.
