'magic' was not being declared consistantly.
some #include <isc/magic.h> were missing from other include files.
NS_SERVER_VALID was not using ISC_MAGIC_VALID.
that the number of seconds in an isc_time_t does not
exceed the range of a time_t, or return ISC_R_RANGE.
Similarly, isc_time_now(), isc_time_nowplusinterval(),
isc_time_add() and isc_time_subtract() now check the
range for overflow/underflow. In the case of
isc_time_subtract, this changed a calling requirement
(ie, something that could generate an assertion)
into merely a condition that returns an error result.
isc_time_add() and isc_time_subtract() were void-
valued before but now return isc_result_t.
The seconds member isc_time_t on Unix platforms was changed from time_t
to unsigned int.
unix/time.c now uses macros for nanoseconds per second, nanoseconds per
microsecond and microseconds per second to make sure that the right
number of zeros appears each place the constant is used.
unix/time.c functions which take initialized isc_(interval|time)_t arguments
INSIST() that the nanoseconds value is less than one full second.
unix/time.c's isc_time_microdiff was broken because it did multiplication and
addition with unsigned integers and attempted to set them a 64 bit int to
avoid overflow, but C's ints don't promote to 64 bits on machines that only
have 32 bit longs. Fixed.
Added all the pertinent documentation to time.h.
Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*

make v6 sockets, but we do not have struct in6_pktinfo.
Add a check in configure.in for struct in6_pktinfo.
Use the result of that check to define (if needed) in6_pktinfo in net.h.
This change makes us build on platforms that have SOME ipv6 structures
(like in6_addr, etc) but not enough to be useful to us.
Note: Before making an ipv6 socket the code should verify that ipv6
sockets can be made using isc_net_probeipv6(). It should also
check for v4 sockets using isc_net_probeipv4() to be consistant.
