This partially reverts commit 8005ca4 by moving the strlcat()
and strlcpy() compatibility implementations back to their original
location.
In addition, these two functions were added to the AC_CHECK_FUNCS
macro. When these functions are available from the C library,
HAVE_STRLCAT and HAVE_STRLCPY will be defined and library version
used. Otherwise the compatibility version is built.
