Fixes#188
When I moved the macro definition below all of the includes, I got the
following compiler warning:
/usr/include/glib-2.0/glib/gmacros.h:246:0: note: this is the location
of the previous definition
#define CLAMP(x, low, high) (((x) > (high)) ? (high) : (((x) < (low))
? (low) : (x)))
So, that's the macro definition that was being used whenever "CLAMP" was
used. It's pretty obvious what went wrong.
This changes the transition_levels_t to transition_scheme_t and
adds two fields day, night of type color_setting_t. This
encapsulates all the information needed to calculate the current
color setting from an elevation.
Build failed on windows platform since pause() is not available. The
function is not needed on the windows platform so we just define a
noop pause() macro.
The gamma adjustments made with the Quartz (OSX) method are tied
to the process so when we exit, the gamma adjustments are reset.
Therefore we need to run a loop that breaks on CTRL-C, after the
gamma adjustments are made.
Hooks are executable scripts in ~/.config/redshift/hooks/ that
are run when a certain event happens. The first parameter to the
script indicates the event and further parameters may indicate
more details about the event.
The event "period-changed" is indicated when the period changes
("night", "daytime", "transition"). The second parameter is the old
period and the third is the new period. The event is signaled when
Redshift starts up with the old period set to "none".
The static string array period_names contains strings that are printed
but these were not marked for translation. This is fixed now by adding
the _N() macro and calling gettext() when the strings are used.
This keeps a copy of the previous color_setting_t in the loop so
that we can avoid printing the color temperature and brightness if
they did not change.
Changes all set_temperature function in gamma adjustment methods
to take a color_setting_t pointer with the color settings.
Colorramp functions are similarly changed to take a color settings
struct.
Move color settings (temperature, gamma and brightness) into a
struct for each period (day, night). Change the interpolation
function to interpolate all values between these structs.
This simply runs a GLib main loop when the location is requested
and tries to get the location from GeoClue2. We need to run a
main loop since the location is not immediately available, instead
it becomes available through a signal.
Implemented through config options transition-high and transition-low (there
is no command line switch at this point). Determines at what solar elevation
Redshift will change from night to transition period to day.

This was basically a hack that happened to work because the Gnome Clock
applet could store the current location of the user, and Redshift was able
to fetch this location through GConf. Since Redshift for some time now has
supported a config file where the location can be set, there is not really
any reason to use an external, fragile solution to do the same.
This should fix a bug where command line options for the "manual" location
provider cannot override the config file. To keep compatability with previous
versions the command line parser will still special case parsing "-l LAT:LON"
and set the correct options in "manual".
This method does not do anything but print the temperature to the terminal.
An external program implementing a color temperature adjustment scheme that
is not supported by redshift can use this method to determine the desired
color temperature. It is also useful for testing other parts of redshift on
systems where neither RandR nor VidMode works.
