Redirect libselinux logging to dmesg for ueventd.
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).

init/ueventd: adds wildcard matching for ueventd rules
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().

ueventd: fix a busy loop while reading uevents
Under certain conditions, poll() may raise the POLLERR
flag along with POLLIN, in which case the check for
(ufd.revents == POLLIN) results in an endless busy loop.
The following fix was applied to
hardware/libhardware_legacy/uevent/uevent.c
to fix a similar bug:

init: Change umask of forked processes to 077
Modify init to set the umask to 077 when forking processes.
This helps protect against inadvertant information disclosure
in init's child processes.
ueventd: Keep umask at 000. uevent needs to be able to
create device nodes with exactly the permissions it
indicates.
Testing:
1) Do an "ls -lR /data /dev" on the device before and after
the umask change and diff the output. Verified by hand
that the permission change wouldn't cause any problems.
2) Verify that package installation works, and the permissions
are as expected, when installing a program from market and
"adb install".

defer firmware load until after filesystems are mounted
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.
