6b0198c2d7 Replace all CROAK calls with assert or LOG_FATAL 
Remove croak() and use assert() or LOG_FATAL() everywhere. Hopefully
the problems with debugging mentioned in the croak() comment are long gone.

cb28aeeacc Add nanosecond slewing to Linux driver 
For offset adjustments below 10 microseconds use kernel PLL with
locked frequency and 1s time constant.

f6320e7050 Don't hang in our_round

when the normal RTC tracking is enabled.

be4369936b Clamp tick value before calling adjtimex 
If tick is outside allowed adjtimex range, clamp it and log a warning
instead of aborting.

1a7415a6ab Return actual frequency in drv_set_freq functions 
This is needed to keep sourcestats accurate when the actual frequency is
different from the requested frequency due to clamping (or possibly
rounding in future system drivers).

15e154c09d Handle immediate step in local module instead of system driver 
This fixes the problem where scheduler wasn't notified about performed
steps and it also makes the command available on all supported systems.

Don't call adjtime to determine remaining offset when there is no slewing
running.

dd4fb511a5 Don't lose remaining adjtime in initiate_slew 
initiate_slew is called also from set_frequency which doesn't read
the remaining adjtime. This wasn't a problem before commit 8c0f3f4
as offset_register was 0.0 and initiate_slew immediately returned.

8c0f3f4042 Try to minimize adjtime error 
The offset is rounded before calling adjtime and the error below
microsecond is accumulated.

35e662d810 Add mlockall and SCHED_FIFO support 
The attached patch adds support for mlockall() as well as the SCHED_FIFO
real-time scheduler. It should result in reduced (and more consistent)
latency. Usage is documented in all the documents.

8f9c237010 Leap second support 
Leap second status is accepted and forwarded to clients if majority
of selectable sources agree. The actual insertion/deletion is supported
only on Linux now.

should switch to.

8884034104 Equivalent to V1.19.99.1 
This is a verbatim copy of the files at that stage of the repository that was
built from the CVS import.  It allows future development to see a bit of recent
history, but without carrying around the baggage going back to 1997.  If that
is really required, git grafts can be used.
