The 32-bit integer part of the NTP timestamp overflows in year 2036,
which starts the second NTP era.
Modify the timestamp conversion to shift values between 1900-1970 (in
the first era) to the second era to enable the client to measure its
offset correctly until year 2106 (assuming 64-bit time_t).
Also update the conversion from double used when stepping the clock to
work with 64-bit time_t after reaching the maximum 32-bit value in 2038
and the server conversion to work correctly in the next NTP era.

The memcpy invocations in the subCommand function, modified by this
commit, previously used memcpy with overlapping memory regions. This is
undefined behavior. On Alpine Linux, it causes BusyBox ed to crash since
we compile BusyBox with -D_FORTIFY_SOURCE=2 and our fortify-headers
implementation catches this source of undefined behavior [0]. The issue
can only be triggered if the replacement string is the same size or
shorter than the old string.
Looking at the code, it seems to me that a memmove(3) is what was
actually intended here, this commit modifies the code accordingly.

Various tools are Linuxish and should thus only attempted to build on
Linux only. Some features are also Linux-only.
Also, libresolv is used on all GNU platforms, notably GNU/Hurd and
GNU/kfreeBSD.
