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.
