are not a timedelta sensor any more on query on the fly anyway

we know its idea without scanning all again

new sensors showing up will be announced that way when slacking ml comes
back from food

to use. "sensors *" just uses all. untested due to lack of hardware.
hacked on the road somewhere between vancouver and calgary

other things work.  ok henning

now. untested due to lack of hardware, and it wouldn't have worked in the
plane anyways. work in progress, currently picks up and uses all sensors
it finds, config file bits to be added soon. theo fine with this going in

make priv_adjtime() deal with offsets, not peers.

first bits from a way to long flight

instead of crash. Test case originally found by cloder@, fix tested
by many.

spotted by ray some time ago

region succeeds, but allocation a required page dir failed. This
can happen if we're really close to ulimit after allocation the
region of the size requested.  See malloc_ulimit1 regress test.
Tested by many; thanks.

root node doesn't have a parent, and POSIX does not say what should be
done in that case. Warn developers that different implementations
may do different things.

pointer to the freed root node, but return a pointer to the new
root node. POSIX does not define, what should be returned in
that case.
Fixes Coverity CID 2528.

remove redundant check on size. ok millert@ deraadt@

actually help us find bugs later (with lint, not cc), if they get
introduced

- Fix semantics: seekdir(pos); telldir() shoud return pos. The code
that implements this will be made faster in a later commit.
- We loose documented behaviour (after closedir() the telldir()
positions are not valid anymore). This was never in Posix, and most
other systems have nothing like it.

code.  "slap it in" deraadt@
