Currently, the fixup code in fixup_sys_perms() scans through all
entries in uevent*.rc. If it finds a match, then it performs a fixup.
If there's no match in that file, no fixup is performed.
SELinux file labels are independently stored in /file_contexts,
with no relationship to the files in /ueventd.rc. Even when no
entries exist in ueventd.rc, we still want to fixup the SELinux
file label in /sys when a uevent message occurs.

If the encryptable partition is wiped (4KB worth of 0 or 0xff),
then reboot into recovery to format /data+/cache
This is while waiting for the Mac OS support to format f2fs.
The flashstation running on Mac OS will currently just erase userdata
and not format it with f2fs.

+ Add a new property, sys.init_log_level, which can be set after init
bootstrap. This will control the level at which init does prints to klog.

We already do this for init, but had failed to do it for ueventd
and could not capture any logging from libselinux calls made by
ueventd.
Truly enabling non-error logging also requires uncommenting a line
in Android.mk:
LOCAL_CFLAGS += -DLOG_UEVENTS=1
which enables other logging and sets the default log level to INFO,
or otherwise changing the klog level in the ueventd code (is not
settable by init.rc loglevel).

Add the ability to boot up directly from charger mode, instead of forcing
charger mode to initiate a full restart to launch 'full' android. This
should shave a few seconds off of boot time on supported devices (just
manta for now).

The sysfs nodes can change from devices to devices for
a particular class of peripheral. Some of them even change
after suspend/resume, e.g. rfkill for USB bluetooth adapters.
This patch adds to the way how ueventd rules with wildcard are
handled. In addition to matching the prefix with a trailing
wildcard, now rules can have wildcard anywhere in the rule.
The wildcard matching is implemented using fnmatch(), where
its matching is simliar to shell pathname expansion. It suits
this particular usage model well. To avoid abuse, the number of
slashes has to match between path name and the rule.
For example, instead of creating a rule to match:
/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/bluetooth/hci0/rfkill*
, this would suffice:
/sys/devices/pci0000:00/0000:00:1d.0/*/*/*/*/bluetooth/hci0/rfkill*
The prefix matching behavior is retained, such that those
rules do not have to pay for processing penalty with fnmatch().

which are more flexible and easily adjusted.

When ueventd creates a device node, it may also create one or more
symlinks to the device node. These symlinks may be the only stable
name for the device, e.g. if the partition is dynamically assigned.
A corresponding change with the same Change-Id to external/libselinux
introduces selabel_lookup_best_match() to support looking up the "best match"
for a device node based on its real path (key) and any links to it
(aliases). This change updates ueventd to use this new interface
to find the best match for the device node when creating it.

To ensure that well-crafted removable media can't spoof the
internal partitions, for platform devices the controller id
is inside the generated path.
We now do the same for PCI devices. The generated path has
two levels; the PCI domain/bus, and then the peripheral ID.
This lets us get by-name symlinks for PCI media, such as the
SATA controllers on PC-like hardware. The symlinks will be
created under /dev/block/pci/. For example:
/dev/block/pci/pci0000:00/0000:00:1f.2/by-name/
