Alan Jenkins 111e4f81ff replace strncpy() with strlcpy() 
The problem was strncpy() doesn't stop after writing the terminating
NUL; by definition it goes on to zero the entire buffer.

I spy another use of strncpy in udev_device_add_property_from_string(),
which is responsible for another ~1% user cpu time...

Alan Jenkins fa0e955a93 libudev: util - optimize path_encode() 
Since we already know the length, use memcpy() instead.
Measured 2% _user_ cpu time reduction on EeePC coldplug.

Alan Jenkins b29a5e4ab9 use more appropriate alternatives to malloc() 
Use calloc to request cleared memory instead.
Kernel and libc conspire to make this more efficient.

Also, replace one malloc() + strcpy() with strdup().

Alan Jenkins 836dcf951c udevd: avoid overhead of calling rmdir on non-empty directories 
Unfortunately the linux rmdir implementation unhashes the dentry
even when the directory is not removed.  This is apparently by
design (for filesystems that don't allow deleting open files).

Results from time(1) and oprofile follow.
