Kenny Levinsen 09c5e9a8dd Ensure step time is at least 1 second
When configured to perform a very quick transition, the step time for 25
kelvin may end up being less than 1 second, rounding to zero. A zero
step time does not make any sense.

Kenny Levinsen 2e7d793bb6 Store enabled state on output
This allows us to check the name just once when we receive the
xdg_output::name event instead of every time we set the temperature.

Artur Sinila afc09a90c6 Support running only for specific outputs (displays)
Useful for laptops with external displays connected. External displays
usually have an ability to adjust color temperature via built-in menu,
so you can run `wlsunset` exclusively for laptop's internal display.

Also different screens happen to look differently after setting the same
color temperature. Possibly has to do with the technology which
display is based on (TN or IPS).

Evgeniy Khramtsov 601dfc87ff main.c: define timezone to tm.tm_gmtoff on FreeBSD
FreeBSD has BSD extension timezone, which conflicts with XSI extension
with the same name, according to time.h:

char *timezone(int, int);	/* XXX XSI conflict */
...

FreeBSD also has long tm_gmtoff member of struct tm, which is offset
from UTC in seconds, according to time.h:

struct tm {
...
long    tm_gmtoff;	/* offset from UTC in seconds */
char	*tm_zone;	/* timezone abbreviation */
}

which is the same as XSI extension timezone.

The new -S/-s/-d flags allow for manually specifying the time of sunset,

This is implemented by sidestepping the calc_sun call in manual mode.
The rest of wlsunset operates as usual.

Kenny Levinsen bcbca9e065 Use illuminant D for the majority of temperatures
D65, the natural whitepoint that wlsunset assumes, is defined on
illuminant D, which simulates daylight with atmospheric effects.
However, we used planckian locus for all values under 6500 K, which
meant that there was a significant jump in color - specifically, a
sudden reduction in green and blue - as we started reducing the color
temperature.

Instead, we purely use illuminant D down to 4000 K where it is well
defined. Below 4000 K, illuminant D starts unintentionally approaching
the planckian locus, before finally breaking completely at 2000 K. We
extend the boundary of illuminant D to 2500 K and perform a
sine-smoothed transition to planckian locus from 4000 K to 2500 K to
extend the range of wlsunset down to 1667 K, where planckian locus ends
and we finally give up.

The end-result is a smooth transition along all valid temperature
values, with no sudden jumps as we had before. However, we do end up
with slightly greener/bluer colors than earlier. We'll have to see how
that holds up.

Kenny Levinsen 49ad3ce7a8 meson: Disable implicit-fallthrough
Clang cannot decide how it wishes to handle implicit-fallthrough, with
different solutions across different versions, which presents a problem
on FreeBSD where several majors of clang remain relevant.

Disable implicit-fallthrough until clang has figured out what it wants
to do in life.

Kenny Levinsen b9f0b8e3c0 Move longitude time correction out of calc_sun
calc_sun reported sun trajectory in seconds since the start of a UTC
day, as they would occur for the specified UTC day. The caller would
then add the UTC timestamp for the start of a UTC day to these numbers.
This lead to complications, as e.g. a sunrise in China would be a
negative value, as it occurred in the last UTC day.

Futhermore, the start of a UTC day was used to signal the need for new
sun calculations. This would lead to recalculations to possibly occur
after its results were needed, such as after sunrise when the target
longitude deviated significantly from the prime meridian.

To fix this, we apply longitude time correction to the start of day
calculation. This way recalculation will occur on the start of the
longitude local day, close midnight for the observer.

We also remove the longitude time correction from calc_sun, so that it
simply returning the number of seconds since the start of the local day
of the observer. The caller then adds the start of the longitude local
day to get the final numbers.

Kenny Levinsen e14e8efcf3 Gracefully handle midnight sun/polar night
The sun trajectory calculation previously emitted garbage if midnight
sun or polar night phenomena was in effect. To fix this, the calculation
is overhauled to report if the computation failed, and if so, which
specific phenomena was the cause.

Timing recalulation uses this information to change out of the normal
state that uses the four sun position timings, into a static state where
wlsunset simply waits a day at a time for a normal sun trajectory
pattern to be restored. In this state, a fixedc high/low temperature is
set as appropriate for the phenomena.

A transition phase replicating the previous day's sunrise is used to
smooth out entry into a midnight sun, which would otherwise cause a
jarring instant-daylight setting.
