Subject: [PATCH 0/30] W1: w1 core fixes, ds2490 updates, strong pullup

What follows is a long list of fixes and enhancements to the one wire
system, and even some documentation.

I no longer have any deadlocks, a thread was eliminated (along with
its one second wakeup interval), the cpu and time overhead are much
reduced for one wire accesses.  The time for the ds2490 to read a
temperature sensor went from 3.91 seconds (.002s user, 3.001s system)
to 0.860 seconds (0.004s user, 0.004s system).  I also added support
for the strong pullup to provide more current when requested.

Note, only the documentation patch 29 differs from the previous set of
patches sent July 11th.
