memcpy.3: remove BUGS section allowing overlapping strings

The removed text claimed that memcpy is implemented using bcopy and thus
strings may overlap. Use of bcopy is an implementation detail that is
no longer true, even if the implementation (on some archs) does allow
overlap.

In any case behaviour is undefined per the C standard if memcpy is
called with overlapping objects, and this man page already claimed that
src and dst may not overlap.

Add notes about overlapping copies.

Add notes to each of these that specifically state that results are
undefined if the strings overlap. In the case of memcpy, we document
the overlapping behavior on FreeBSD (pre-existing). For str*, it is
left unspecified, however, since the default (and x86) implementations
do not handle overlapping strings properly.
