I've created reconnect feature - if on start there are no registered families
all new devices will have defailt family, later when driver for appropriate
family is loaded, slaves, which were faound earlier, will still have defult
family instead of right one. Reconnect feature will force control thread to run
through all master devices and all slaves found and search for slaves with
default family id and try to reconnect them.
It does not store newly registered family and does not check only those slaves
which have reg_num.family the same as being registered one - all slaves with
default family are reconnected.

Support for new simple rom family [0x81 id].
It is the same as existing 0x01 family,
which is used in ds9490* w1 adapters.
Patch is on top of new-thermal-sensor-families patch.

Support for ds18b20, ds1822 thermal sensors.
Based on code from Tiziano M_ller <tm@dev-zero.ch>.
Patch is against 2.6.12-rc2 and should be applied
without problems on top of any later kernels since
w1_therm driver was not changed.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
