free vis_user

malloc vis_user (why 1.6 branch has the fix already?)

verify strvis() buffer length is enough. make sure string termination before
use. remove extra ntohs() which is not needed. from Charles Blundell

Allocate vis_user on the stack instead of using malloc(). This
way we don't have to worry about malloc() failure. Also closes
a memory leak since vis_user was never free()d. Lack of malloc()
checking pointed out by Peter Werner.
from openbsd

Lineup comment and remove unnecessary whitespaces.

Use \a instead of embedding raw control-G character.

Formatting nit: add a space.

make sure big_buf is big enough to hold line terminations.
if all the lines have N_CHARS of characters, we will write up
N_CHARS * N_LINES + (3 + 2 * N_LINES) + 1

- use getnameinfo instead of gethostbyaddr

find_user() in process.c does an unbounded copy into a destination
buffer that is smaller in size than the source buffer.

also, there is no guarantee that any of the string components of
the request packet are null terminated.

in some cases, not all elements of the response buffer are
explicitly set. specifically pad and addr. a talk client can spy to
see which host is talking to which host by sending out regular
packets, to which talkd responds without clearing the addr element.
