Allow DELAY() to be called anytime:
...
-don't enable interrupts at the end of gettick(), restore the previous
state instead
-start timer/counter 0 from delay() if necessary
-comment out "findcpuspeed()", it would clobber the timer again, and it
is unused anyway

Import Dennis Ferguson's i386 clock change request from PR 2785:
...
* Add table-driven assembly-coded microtime().
* add boot-time computation of the interpolation table,
allowing the hand-coded microtime() to work with locally-tuned
nonstandard values of HZ or TIMER_FREQ.
* delete old C version of microtime().

Eliminate obsolete TIMEZONE and DST options.
...
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

check CMOS time against base time, for sanity. if CMOS time invalid,
...
warn user and user base time. if base time < 1985, warn the user.
if base time 5 or more years different than clock time, warn user,
and if it's base time that's greater, use it. (The latter case is
handy if one has a machine in which the CMOS battery is dead... I do.)
