Log Message:
Fix overlapping strcpy usages

Using overlapping src & dest witgh strcpy is undefined, so anything
like
	strcpy(str + N, str + M);
is automatically invalid, regardless of the valuse of N and M.

Change offending usages here to use memmove() instead.

Note: 2 issues:  First, there is no (in sntp/compat) anything to deal
with the possibility that memmove() is not available - this should not
be a problem building nbsd, but it might be if any attempt were to be
made to upstream this change (the autoconf machinery to detect memmove()
would be needed, along wth a memmove() implementation).

Second, and more serious here, I haven't been able to get a build to
actually compile this code, so while I believe it is correct, I am unable
to test it.   This is intended to fix the sh3 builds on in the releng
daily builds, so we will see what happens.  As best I can tell my build
is essentially identical (though I would be using a different base system
for the build).
