unix(4): Fix/add markup

Untabify examples, .Bd -literal -offset indent doesn't seem to mesh
with tabs nicely in the PostScript output.  The indent is probably not
a multiple a of literal tab width.  This causes a small vertical
misalignment for tab-indented lines, but what's worse - it can cause
an extra tab in some cases (and did here for the unpcbid definition).

Change back various occurrences of \*[Le], \*[Ge] (less/greater equal)
and \*(ua (upwards arrow) to literal "<=", ">=" and "^" whenever
appropriate (e.g., in code examples).

fix references in manual pages to the reference documentation

introduce a SOL_LOCAL for unix-domain socket level socket options
as an alias of the current 0 used for these options, as in FreeBSD.

Direct reader to shell documentation generally, rather than csh(1)
specifically.

Mention variables OLDPWD and PWD.

Move the text that explains that cd(1) is a shell built-in to the very
beginning of the description where it can be seen prominently.

Improve formatting.

Remove workaround for ancient HTML generation code.
Use EXIT STATUS and .Ex.

Remove workaround for ancient HTML generation code.

Add sc_pid to sockcred so that SOCK_DGRAM and LOCAL_CREDS socket option
can learn the process id of the AF_LOCAL sender.
Add compat glue for old structure.

Bump date for SOCK_SEQPACKET; add serial commas.

Document that SOCK_SEQPACKET is supported

Fix some typos and incorrect idioms with the cmsg botch^WAPI.

Add a couple cross-references too.

ok wiz

Use .In instead of .Aq Pa for header files.

file unix.4 was added on branch uebayasi-xip on 2010-03-22 18:58:32 +0000

Use .In instead of .Aq Pa for header files.

Rewrite the sentence about the socket options to avoid questionable
typographic layout and to be more inline with the wording of the rest of
the man page.

Add a new socket option for unix domain sockets: LOCAL_PEEREID, to make
it possible to get the pid, euid and egid of the process at the remote
end at the time it did bind() or connect().

Add a new libc function, getpeereid() to easily get at the euid and egid.
As a consequence, bump libc's minor number.

Document the LOCAL_PEEREID socket option in unix(4).

Based on contribution by Arne H. Juul, minor modifications by myself.

Bump date for previous. New sentence, new line.

Moved example code into its own section with an additional path truncation
check. Added a COMPATIBILITY section for sun_len and SUN_LEN() as suggested
by soda. Fixes PR lib/34744.

Make HTML-output safe. Use more macros.

note that sun_len is ignored, per discussion on tech-net

add example on how to use SUN_LEN()

fixed lib/34744 by Christian Biere

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22309, verified by myself.

Point to IPC tutorials in /usr/share/doc/psd, update names, and add authors.
Bump date.
Suggested by kleink.

Use
.In header.h
instead of
.Fd #include \*[Lt]header.h\*[Gt]
Much easier to read and write, and supported by groff for ages.
Okayed by ross.

Generate <>& symbolically. I'm avoiding .../dist/... directories for now.

Boring whitespace fixes.

Improve usage of `comprise' according to Webster and misc/10893
by Jim Bernard.

Fix minor formatting error.

Indent structure member.

Document LOCAL_CREDS socket option.

Pull rev 1.4 up from trunk (fair)

Document the SUN_LEN() macro as suggested by PR#3804,
with wording modified for clarity.

Last sentence of the patch omitted because I do not understand what
it means, even after some examination of the unix domain kernel code.

Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.

imported from 4.4lite

Add RCS identifiers.
