ac218d9cc8 determine at rule parse time if we need to call fnmatch()
This cuts down the large rule set's 120.000 calls to fnmatch() to
51.000, and we can just call strcmp for the simple matches.

154a7b8428 cache uid/gid during rule parsing
This cuts down the number of parsing /etc/group from ~700 to 11,
with some large rule files installed.

7aeeaedc5f udevd: fix WAIT_FOR_SYSFS execution order
The wait should be ordered after matching KERNEL, ENV, etc.
but before ATTR.

Without this, WAIT_FOR_SYSFS rules will be applied unconditionally
to all events.

with the token list:
  109232 bytes tokens (6827 * 16 bytes), 71302 bytes buffer

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().
