Before calling PKL_ReplyLength() check that the packet has full header.
This didn't change the outcome of the test if the packet was shorter as
the invalid result from PKL_ReplyLength() was either larger than length
of the packet or smaller than header length, failing the length check in
both cases.
List of selectable sources that is used in combining was trimmed to
sources with prefer option, but scoring algorithm considered all
selectable sources. When a source without prefer was selected and
no source was combined, it caused assertion failure.
This is a revert of commit 99d18abf updated for later changes. It seems
in that commit the calculation was changed to match the reversed dfreq
added in 1a7415a6, which itself was calculated incorrectly. Fix the
calculation of updated frequency and matching dfreq.
Add new DEBUG_LOG macro for debug messages. The messages are enabled
when compiled with --enable-debug and they are printed when the -d
option is used twice.
The Clang static analyzer scan-build from Debian clang version 3.4-1
found the following unneeded assignment.
rtc_linux.c:756:5: warning: Value stored to 'error' is never read
error = 1;

Indeed, if in that if branch, the function returns without ever looking
at the variable `error`. So remove the line.
Implement a driver which allows using PTP hardware clock (PHC) as a
reference clock. It uses the PTP_SYS_OFFSET ioctl or clock_gettime()
to measure the offset between the PTP clock and the system clock. Ten
readings are made for every driver poll and the fastest one is returned.
As PHCs are typically kept in TAI instead of UTC, it's necessary to set
the TAI/UTC offset manually by the offset option. This could be improved
by obtaining the offset automatically from the right/UTC timezone.
