870039320f Changed all paths to be relative to src/lib instead of src/lib/libc
so that all these makefiles can be used to build libc_r too.

Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.

Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.

beb9f61579 Fix problem with FD_SET* overflow reporting.. Perror() didn't have enough
args, and errno hasn't actually been set so it probably doesn't make sense

3951b8e32c Small yet significant tweaks/cleanups:
- getservent:
  o put _yp_check() proto under #ifdef YP where it belongs
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- gethostbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long

- getnetbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- ether_addr:
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
    but it happens that BUFSIZ == YPMAXRECORD.

- gethostbydns:
  o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)

These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.

f360d1effe Another one-liner: remember to NUL terminate local copy of NIS host
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.

6b73680dcf Make the __dns_getanswer() wrapper work right. For the newer versions
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. :)

380577b434 I asked Bill Paul why _getnetbynis() was only being called with 2 parameters,
and he said:

	The 3rd agrument is new; looks like it was part of the upgrade to
	a new BIND with some IPv6 support. The third argument here should be
	AF_INET. In order for it to be anything else, I'd have to add new
	NIS functions to support IPv6 lookups. I don't even know what those
	look like yet.

So there ya go, add AF_INET as the 3rd argument to the call.

f991bb5181 Sigh, back out the last bright idea I had here about compiling the res_*
routines from contrib/bind directly.  There were too many problems,
including having to add -DUSE_OPTIONS_H to the entire libc source in
order for the contrib code to pick up it's options, and so on.

Instead, I've merged the changes, libc is now self contained again.

Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).

I've created a new header (pthread_np.h) for the non-POSIX stuff.

The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented
doesn't work. I think its best to delete it. I don't think libc_r needs
tags anyway, 'cause most of the source is in libc which does have tags.

also:

Here's the first batch of man pages for the thread functions.
The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was
inherited from /usr/src/lib/libc/Makefile that should only be done with
libc.

also:

I should have sent this diff with the pthread(3) man page.
It allows people to type

make -DWANT_LIBC_R world

to get libc_r built with the rest of the world. I put this in the
pthread(3) man page.  The default is still not to build libc_r.


also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.
