When using device tree, platform devices may not have a
/devices/platform/ path prefix, but can be rooted in
/devices/.
Modify the platform device tracking code to store the device
path as well as the name. This way, when we create symlinks, we
can correctly skip the base platform device prefix and get to the
proper device node path.

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.

To support runtime policy management, add support for reloading
policy from /data/system. This can be triggered by setting the
selinux.loadpolicy property to 1, whether from init.rc after
mounting /data or from the system_server (e.g. upon invocation of
a new device admin API for provisioning policy). ueventd and
installd are restarted upon policy reloads to pick up the new
policy configurations relevant to their operation.

Automatically set the SELinux security label on directories created
by init.rc. This avoids the need to separately call restorecon on
each such directory from the init.rc file. Also restorecon /dev
and /dev/socket after initial policy load so that they are labeled
correctly before any other dev nodes or sockets are created.

Change uevents may be triggered after new files are created on a device
in /sys, run the sys permissions fixup when they occur.

Add SE Android support for init and ueventd.
init:
- Load policy at boot.
- Set the security context for service daemons and their sockets.
- New built-in commands: setcon, setenforce, restorecon, setsebool.
- New option for services: seclabel.
ueventd:
- Set the security context for device directories and nodes.

The mmc block devices on panda boards use a platform device called
omap/omap_hsmmc.0. The number of path entries in the uevent after
the platform device is unknown, and the number of path entries in
the platform device is unknown, so the only way to determine how
many entries make up the platform device is to compare against
a list of platform devices.
Add a list of platform devices that have been registered, and
iterate through it to determine the platform device portion of
a block device uevent.

In some situations a driver could try to request firmware before
/system is mounted. Previously we'd fail the request. Now we
will retry the read-from-filesystem every 100ms until we find the
firmware or we've finished the "fs" and "post-fs" stages of init.

If firmware is not found, write -1 /sys/$DEVPATH/loading to cancel the
firmware load. Otherwise the driver has to wait for the 60s timeout.

This should be much nicer than peppering init.rc with chown/chmod
directives.
Also, remove some dead code and obsolete comments.

- look in /vendor/firmware/... in addition to /system/etc/firmware/... for firmware loading
- add /vendor/bin to path before /system/bin
- add /vendor/lib to ldpath before /system/lib
- configure appropriate permissions for /system/vendor/bin
- symlink /vendor -> /system/vendor

Use makedev helper for device major and minor numbers
Major and minor numbers can be greater than 255. Major numbers
are 12 bits, and minor numbers are 20 bits. Supporting major
and minor numbers > 255 allows the use of the extended block
device for extra mmc partitions.

Since we now support USB host mode, devices might get a different device
file depending if other devices are connected on the host port. This
patch creates symlinks to USB character devices that depend on the port
devices are connected to, but not on the order they have been probed.
(e.g. /dev/usb/tty2-1:1.0 -> /dev/ttyUSB0)

init now creates files in /dev/bus/usb/ for user access to USB devices.
Files are chmod 660 with group AID_USB.
