543315b700 Reversed order of arguments to clock_time_conversion. 
Now the order of argument matches the clock_cast function.
The test only is_clock_castable trait still matches is_convertible
order of arguments.

b13c859ff1 Restored deprecated to_clock_time function. 
Fixed the to_utc_time(const gps_time<Duration>& t) function
to correctly use clock_cast<utc_time>.

Added test to deprecated functions.

d4592bd497 Maked clock_time_conversion as const and used alias. 
Marked operator() of all supplied clock_time_conversion overload
as const.
Changed input type to sys_time/utc_time alias when possible.
Used consitient nomencalture: st for sys_time, ut for utc_time
and tp for time in different clock.

58a4a9518a Mismatch in return type of converting function is now hard error. 
Change the implementation, in the way that mismatch in return
type of the from/to_sys/utc functions (not returning time_point,
or returning time_point with inappropriate clock) leads to
hard error.

Added appropariate fail test for to_sys function, including:
* returning an int
* returning time_point of wrong clock
* reutrning reference to time_point

5a9b44a37a Implemented test for casting non-wall clocks and detecting that clocks cannot be casted. 
Added test that detects if clock_cast<Dest>(Source) properly
SFINAEs if clock's are not castable, this includes test for
steady_clock that is not castable to any wall-clock.

Secondly added steady_based_clock based on steady_clock
(as name indicates), that clock_cast may be extended to clock
non-related to wall-time (sys/utc) using conversion traits.

Final example is pair of ambiguous clocks (amb1/amb2_clock) that can convert
to each other either using sys_clock or utc_clock.
Then the conversion from amb2 to amb1 is disambiguated
via trait specialization.

a9d2907fa1 Implemented test for custom clocks derived from sys_clock. 
Created mil_clock and s2s_clock, that are both using to_sys/from_sys
function and are fully interoperable with existing clocks (including
ones based on utc).

Implemented an trait is used to provide direct conversion
from s2s_clock to mil_clock without converting to sys_clock
(conversion counter is used for this purpose).

bf5a4f3cd5 Implemented test for existing clocks. 
Implemented test for conversions between existing clocks
(sys_clock, utc_clock, tai_clock, gps_clock) showing that
they can be used instead of to_clock_time functions.

e1099ef3ab Implemented clock_cast function. 
Added an clock_time_conversion trait, that should be specialized
with SourceClock and DestClock respectively and provide an function
that convert time_point in SourceClock to equivalent time_point
in DestClock.

This function has following specializations:
1) <sys_clock, utc_clock> - convert sys_time to utc_time
2) <utc_clock, sys_clock> - convert utc_time to sys_time
3) <Clock, sys_clock>     - calls Clock::to_sys if it returns sys_time
4) <Clock, utc_clock>     - calls Clock::to_utc if it returns utc_time
5) <sys_clock, Clock>     - calls Clock::from_sys if it returns time_point<Clock>
5) <utc_clock, Clock>     - calls Clock::from_utc if it returns time_point<Clock>

Implemented an clock_cast<DestClock>(time_point<SourceClock, Dur> st), that
works as follow:
1) If DestClock is same as SourceClock, returns std
2) Otherwise, if clock_conversion<SourceClock, DestClock> available, uses it
3) Otherwise, if tries using clock_conversion<SourceClock, CommClock>
   and clock_conversion<CommClock, DestClock> for CommClock being utc_time
   or sys_time
4) Otherwise, tries using clock_conversion<SourceClock, utc_clock>
   and clock_conversion<sys_clock, DestinationClock> or reversed (firstly
   convert to sys_clock, then to utc_clock) to convert.

8b9f0515b5 Replacing 0 with nullptr to avoid GCC warning 
All the calls to `std::time_get::get` had `0` as end-of-range iterator.

E.g.

    auto& f = use_facet<time_get<CharT>>(is.getloc());
	// ...
    f.get(is, 0, is, err, &tm, command, fmt+1);
              ^

Using `nullptr` instead of `0` doesn't trigger the GCC 5.x warning:

> warning: zero as null pointer constant [-Wzero-as-null-pointer-constant]

2032fccbb7 Fix valgrind warning about uninitialized variable use in to_stream() 
tm variable is not initialized in to_stream(), and valgrind warns about
"Conditional jump or move depends on uninitialised value(s)".

This is a false positive, as strftime always reads tm_hour, even if it
ends up never using it. To silence the warnings, initialize tm to zero.
