• fix file description, history, etc.
• require <stddef.h> for portable size_t declaration (if ! kernel, bootloader)
• mention why we do _not_ include <string.h> (for building on obsd/mbsd)
• sync RCSID definition with that of mksh (more portable)
• fix strlcat description
• sync strlcpy obsd rcsid and licence header with obsd-current
(their code change 1.10→1.11 was something we already did)
• use “does not”, not “doesn’t”
• make it easier to produce wcslfun.c
libc wcslfun.c:
• sync with strlfun.c (much easier now)
mksh strlcpy.c:
• sync with strlfun.c (in comments, mostly)
no binary changes
