1e03b754ae udevd: convert to event worker processes
Event processes now get re-used after they handled an event. This reduces
pressure on the CPU significantly because cloned event processes no longer
cause page faults in the main daemon. After the events have settled, the
no longer needed worker processes get killed.

cb14f4543a handle devtmpfs nodes
UDev follows the kernel given name, and re-uses the kernel created
device node. If the kernel and spcecified udev rules disagree, the
udev specified node node is created and the kernel-created on is
deleted.

5ae82640c5 Don't add inotify watch until RUN rules processed.
The programs we RUN can open device nodes, and thus we can end up
chasing our own tail.

bd284db142 udevd: optionally watch device nodes with inotify
This allows you to re-process the rules if the content of the device
has been changed, most useful for block subsystem to cause vol_id to
be run again.

fc7d16f993 cleanup old names before creating the new names
Scott found that the node /dev/pktcdvd can not be replaced by
/dev/pktcdvd/control by changing the rules, and re-trigger the
event. We used to create the new names before we cleaned up the
old ones, which can not work if we need to create subdir with
the same name.

ec2dd02e2a udevadm: test - remove --force option
Since a while we change the database with a "test" run, but do not update
the node and symlinks. We need to "force" all the time, to keep things
in sync.

6880b25d40 replace in-memory rules array with match/action token list
The in-memory rule array of a common desktop distro install took:
  1151088 bytes
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().
