Copy stable/9 to releng/9.3 as part of the 9.3-RELEASE cycle.

MFC all features as of r248336:

The user visable feature is from r246083:

Add -l option to cat(1). This option causes cat(1) to use fcntl(2) to
set an exclusive advisory lock on stdout. This will be used to guarantee
orderly writing to METALOG.

MFC r238653: Use proper error message when fstat(2) fails on stdout.

PR: bin/159746

MFC r238652: style(9).

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Teach cat(1) and cp(1) to use a larger buffer if enough memory is present
in the system. A simple heuristics is used to detect what is "enough"
memory: if number of physmem pages is greater than 32k (equalling 128 MB
on machines with 4 kB pages).

Typical immediate result of these changes is reduction in context switches
and the goal is to increase efficiency by using large buffers:
before: /usr/bin/time -hlp cat file1 > file2
...
163 voluntary context switches
11194 involuntary context switches
after: /usr/bin/time -hlp ./cat file1 > file2
...
417 voluntary context switches
272 involuntary context switches

/*- or .\"- or #- to begin license clauses.

Use warn() instead of perror().

Remove clause 3 from the UCB licenses.

We have to hide copyright[] for gcc33. :-(

Be consistent about declaring a function "static", and consistent
about the type of argv.

Give lint a small bit of help.

Consistently use __FBSDID

Avoid truncating the pathname to UNIX Domain Sockets with snprintf(),
giving a more sensible warning when the (relatively meagre) sun_path
limit is exceeded.

Use an usage() rather than doing the fprintf inside option parsing.

Print the "$" symbol on blank lines when the -s and -e options are used
together.

Remove bogus "-" operand from usage message. There is no restriction on
where it may be placed, it is treated the same as the file arguments.

Fix warnings inspired by lint, a commercial lint and WARNS=4.

Drag cat(1) kicking and screaming into the late 1980's:

o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.

Approved by: arch@, new style(9)

WARNSify.

The "cat - -" feature was broken by the last commit.
Restore the code that avoided closing and reopening
stdin. This is also required by POSIX. As a bonus,
enable multiple stdin reads with the -benstv flags,
by resetting the EOF condition on stdin.

Give /bin/cat the ability to connect to and read unix-domain sockets

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

Sync us up to OpenBSD's cat.1 v1.18 and cat.c v1.9.

This gets rid of a bogus cast of NULL in setbuf().
Lets us know the buffer malloc failed.

Reworks the manpage a bit to make it more mdoc(7) compliant, adds
examples.

$Id$ -> $FreeBSD$

Fix minor style bugs noticed by the Bruce Filter.[tm]

Bruce-Filter-By: bde

Silence -Wall -W -Wkitchen-sink. Use ssize_t in preference to int,
make a char * const that should have been. Use new style function
declaration for main. Mostly a Bruce Filter[tm] test commit.

Restore Lite2 sccsids by removing `const'. Improve documentation a little.
Suggested by: Bruce

Correct use of .Nm, .An and other cosmetics. Add rcsid. Remove unused #inc.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Merge Lite2 mods and -Wall cleaning.

Activate LC_CTYPE locale and additionly use !isprint() for 8bit characters

Merge in the NetBSD changes to cat.c. These appear to have come from
the 4.4 lite 2 tape as well. There are now only two diffs between
NetBSD's cat and FreeBSD's cat:
getopt return value is -1 on NetBSD and EOF on FreeBSD.
NetBSD has added setlocale calls before anything else.

Fix exit status. `cat no-such-file >/dev/null' exited with status 0.
This has been broken since cat's own err() function was sloppily
replaced by the library functions warn() and err().

Added $Id$
