00f98bd2b3 skip entire rule containing device naming keys, if no device can be named 
If rules set NAME, SYMLINK, OWNER, GROUP, MODE, events without a device node
and remove events will skip the entire rule. The old parser did the same.

d15fcce4b3 udevd: be more careful when matching against parents 
I'm worried about what will happen with things like

KERNELS=="*" # pointless rule
KERNELS=="doesnt-match" # another pointless rule

Since TK_RULE < TK_M_PARENTS_MAX, we will try to match all three tokens
against parents of the current device.  I can't think of a bad case,
but it's not exactly good either.

11ae757850 udevd: fix termination of rule execution 
LAST_RULE was broken, and I broke TK_END by making it do the same.
It used a "break" which exited the switch statement, but not the loop!

cd94c04c51 udevd: avoid implicit memset in match_attr() 
Initializing a char array to "" is equivalent to a memset()
call - which is exactly what it gets compiled to.

Fixing this one callsite reduced memset() _user_ cpu cycles
from 2-4% to 0.05% on the EeePC.

e25fa4faf5 udevd: use a tighter loop for compare_devpath() 
This crops up in my threaded udevd profiles from time to time.
It's not consistent - probably due to variations in the number
of concurrent events - but it can hit 4% user time and higher.

The change halves the user time spent in compare_devpath().

836dcf951c udevd: avoid overhead of calling rmdir on non-empty directories

659353f5a9 replace strerror() usage with threadsafe "%m" format string 
strerror() is not threadsafe.  It uses a buffer to build messages of the form
"Unknown error 387689".

syslog() provides a %m format which is equivalent to strerror(errno).
As a GNU extension, this is also accepted by printf and friends.
At least in the current implementation, it is correctly threadsafe.

The scans are now performed up-front at parse-time, instead of being
repeated for each event at run-time.

(excluding the time spent in-kernel).
