here is a patch on top of your nice improvements.
I fixed the whitespace and it hopefully fixes the stupid timestamp bug in
udevd. Some stupid OS sets the hwclock to localtime and linux changes it
to UTC while starting. If any events are pending they may be delayed by
the users time distance from UTC :) So we use the uptime seconds now.

This patch covers a number of areas:
1) sysfs.h is fixed up to use the common dbg() macro. This fixes the
case where DEBUG is defined but USE_LOG isn't.
2) udevstart.c is modified to include the proper headers, rather than
getting them indirectly which can break depending on Makefile flags
3) udevd.c gets some major changes:
a) I added a pipe from the signal handler. This fixes the race
conditions that I mentioned earlier. Basically, the point of the pipe
is to force the select() call to return immediately if a signal handler
fired before we actually started the select() call. This then lets us
run the appropriate code based on flags set in the signal handler proper.
b) I added a number of flags to coalesce calls to common routines. This
should make things slightly more efficient.
c) since most calls will tend to come in with a sequence number larger
than what has been received, I switched msg_queue_insert() to scan the
msg_list backwards to improve performance.

Here's the patch applying the latest libsysfs.
- adds the latest libsysfs code to udev
* new code includes dlist implementation, a generic linked list
implementation. Needed our own because LGPL
* rearranged structures
* provided more functions for accessing directory and attributes
- gets rid of ->directory->path references in namedev.c
- replaces sysfs_get_value_from_attributes with sysfs_get_classdev_attr
