ANSIfy mille(6)

OK tb@

Headers cleanup and also the following:

mille.h:
#define CTRL locally, which is used by move.c and misc.c, to avoid including
termios.h or sys/ttydefaults.h where it's actually defined

varpush.c:
Change _PATH_DEVNULL to "/dev/null" since other systems may not have it defined
but also avoids including <paths.h>

Included a few sugestions from tb@ who also gave his OK

replace setbuf with setvbuf, from Frederic Nowak

Cast ctype functions' arguments to unsigned char.

ok guenther@

Eliminate pointless use of <sys/param.h>, <sys/file.h>, <sys/sockio.h>,
and <sys/ttydefaults.h>
Replace MAXPATHLEN with PATH_MAX and MAXLOGNAME with LOGIN_NAME_MAX
Pull in <limits.h> where needed
Prefer sizeof(var) over MAXFOO or FOO_MAX

ok deraadt@

fix potential bugs spotted by parfait
ok millert@ pjanzen@

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
