cem cdc7a46eeb strcpy.3: Improve legibility and clarity 
In the DESCRIPTION, put the more commonly used functions first in the
corresponding sentence, to help catch the eye.

Pull out the note about overlapping buffers to its own paragraph, as it
applies to all routines documented by this page.

Emphasize the potentially surprising strncpy(3) behavior of zero-filling the
remainder of a buffer larger than the source string.

Encourage strlcpy use; remove portability note about strlcpy(3).  Adapting a
strlcpy-using code base to a platform that does not provide strlcpy in libc
is so trivial as to not be worth mentioning.  (Just copy strlcpy.c out of
any BSD libc, or include and link the pre-packaged libbsd library on non-BSD
platforms.)

Likewise, expand the page's warning about ease of potential misuse to cover
all functions documented herein, and explicitly suggest using strlcpy most
of the time.  The text was mostly cribbed from a similar suggestion in
gets(3).

Finally, document the remaining valid use of strncpy -- the rare
fixed-length record with no expectation of nul-termination.
