Generalize the selection of programs to run based on the existance of files
rather than the OS names that we find. Add comments about me being the
keeper of the OpenBSD mods of this file. Use ftp on OpenBSD rather than
fetch since OpenBSD's FTP supports urls and there is no fetch.

- yp_main.c: Always add the resolver socket to the set of fds
monitored by select(). It can happen that pending == 0 but we
still have some data in the socket buffer from an old query.
This way, the data will be flushed in a timely manner.
- yp_extern.h: remove proto for yp_dns_pending() since we don't need
it anynmore.
- yp_server.c: call yp_async_lookup_name()/yp_async_lookup_addr()
functions with the svc_req pointer as an arg instead of the xprt.
(The svc_req struct includes a pointer to the transport handle,
and it also has the service version number which the async DNS
code will need. (see below))
- yp_dnslookup.c:
o Nuke yp_dns_pending() since we don't need it anymore.
o In yp_run_dnsq(), swallow up and ignore replies if no requests
are pending or the ID doesn't match any of the IDs in the queue.
o In yp_send_dns_reply(), we assume that we will always be
replying to an NIS v2 client. While this will probably always
be the case, we do support the v1 'match' procedure, and it
has a different result struct than v2. For completeness,
support replying to both NIS v1 and v2 clients.
o Update the queue entry structure to include a member to
keep track of the NIS version number.
o Have yp_async_lookup_name/addr() extract the version number
from the svc_req structure and save it with the queue entry
for yp_send_dns_reply() to inspect later.
o Add some comments.

Specifically these changes include:
1) Implement 'trap -l' to get a list of valid signals names. This
is useful if you wanted to do something like reset all signal
handlers to there defaults values, in which case something like
this will do the trick.
trap `trap -l`
2) Reformat the output of 'trap' so it can be saved and later eval'd
to restore the saved settings.
3) Allow the use of signal names as well as signal numbers.
4) Fix trap handling of SIGCHLD so that commands like the following
(albeit, contrived) won't cause sh(1) to recurse ad infinitum.
trap uname 0 20
5) Make variables static that are used only in trap.c.
6) Minor 'style(9) police' mods.
lookup results. Without this, doing multiple host/addr lookups in a
single process yeilds strange results (the buffer is static, and
garbage may be left behind from previous lookups).
I just noticed this in 2.2-BETA. Unless somebody threatens to chop my
hands off with an axe, I'm going to move this to the 2.2-RELENG branch
shortly.
the START UNIT command before testing whether the device is ready.
Maybe it should be done even earlier, i'm not 100 % sure.
Again, CD changers will most likely benefit from it.
While i was at it, also made the debugging case a little more verbose
about why the cdopen() yielded an ENXIO. (Only in effect when
SCSIDEBUG is specified.)
Should eventually also go into 2.2.
error code with ASC/ASCQ 4/1 (``Logical unit is in the process of
becoming ready'') non-fatal. Retry the operation until it will
eventually either yield a real error condition, or finally succeed.
Devices like CD changers or tape drives with a freshly inserted
cartridge should benefit from this.
Should go into 2.2 after some testing in -current. I'd like to see
this in the release if possible.
- Don't dereference a NULL hostent pointer (if T_PTR lookup fails).
- Today I asked myself: "Self, you wrote this nifty async resolver
that does a great job handling delayed replies to clients using
the UDP transport, and the yplib code in libc always uses UDP
(except for yp_all()). But what if some dork makes a DNS lookup using
TCP?" Being the only dork on hand at the time, I tried it and was
enlightened. As I suspected, my transaction ID frobbing hacks cause
fireworks if called on a TCP transport handle (duh: the structures
are different). Fix: check the type of socket in xprt->xp_sock using
getsockopt() and don't use svcudp_get_xid() and svcudp_set_xid() for
anything except SOCK_DGRAM sockets. (Since accept() gives you a
new socket for each connection, the transaction ID munging isn't
needed for TCP anyway.)
of BIND, we need to tweak some things to that gethostanswer() knows
whether or not we're dealing with an IPv4 or IPv6 address. (This'll
teach me to use a 2.1.0 system for NIS development -- but it's so nice
and stable I just can't being myself to upgrade it. :)
Turn off error messages from locate(1), we can't do very much about
its database not being ok anyway at this time.

- A major 11th hour, last second, untested commit!
Build some infrastructure to clean up the compat lib distributions, and
also allow them to be installed from the source tree rather than having
to to and get the tarballs from freefall or a CD. Some tweaks to
/etc/make.conf are in the pipeline to enable it.
This came about because it became apparent that we'd have to change the
compat21.tgz tarball to fix the NIS problem with 2.1.x binaries. Since
it's tar..gz.uu, doing this would have caused a huge repository change
and we may as well try and fix it once and for all. Now, adding/removing
libraries should have MUCH less repository impact.

Add a little more sophistication to the md5 grep command.
Change the md5 checksum logic a bit. Now, the message is printed
out for every successfully/unsuccessfully matched checksum, and it
aborts at the end if there was a mismatch. Also, make missing checksum
and IGNORE file inconsistency fatal, as there is now no reason to have
a missing checksum.

While i was at it, also reject IO requests that are not an integer

workings of #error in particular. He also broke the 2.2 build with this
change, leading me to wonder whether or not the changes were ever even
tested. Folks, I'm happy to see people work directly on 2.2 like
this and will continue to encourage Nate to make direct commits, but
please TEST before committing! I think that's a more than reasonable
prerequisite, and this code could never have worked at all, leading me to
believe that Nate skipped this most basic of steps.
