Defines: strend()

strend(s) returns a character pointer to the NUL which ends s. That
is, strend(s)-s == strlen(s). This is useful for adding things at
the end of strings. It is redundant, because strchr(s,'\0') could
be used instead, but this is clearer and faster.
Beware: the asm version works only if strlen(s) < 65535.
