- add -p pathsep option
- make wrap to zero work, but produce a warning
While here:
- fix gcc warnings, in particular variable clobbered warnings
(compiling with fewer warnings does not really fix the problem)

Default to WARNS=4
Exceptions that need a lower level are:

plus there's already such a feature elsewhere, so let's try to not
diverge needlessly)

More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages. Many more to
come.

Fix for bin/4637, mostly as discussed on current-users.
Allow relative file writes,
For relative file accesses, no longer continues searching dirlist once we find
_any_ file, even one for which we don't have access,
If no dirlist was given on the command line, apply same permissions check as
with 'absolute' requests before allowing access.

Remember the interface the request comes in on, so we will reply to the
same address. This fixes tftp'ing to lo0 aliases.

Use S_IS*(), not S_IF*.

WARNS?=1. merge lite-2.

get rid of supplementary groups.

The tftpd daemon must be invoked as root in order for the chroot()
call to succeed, and must give up those privledges as soon as the new
root has been aquired. Use setgid() & setuid() to explicitly set the
user and group IDs to non- priveleged values.

This change now requires tftpd to be executed by root. I haven't
studied the security implications of making it setuid root, so
inetd.conf needs to be changed to start it as root.

Fill in sin_len.

From Christos Zoulas <christos@deshaw.com>:
As promised. the problem was that tftpd would core dump if given no arguments.
I fixed it to use getopt. I also changed 0 to fd, because I had added some
debugging code that allowed me to start it from the command line.

Add -s flag, per Roland McGrath, with changes and a manual page addition by me.

Add RCS identifiers.

Cleanup for GCC 2.
