Sync usage with man page.

Add an option to read with a different buffer size, and document the

for example which cannot handle seeking.

 - Applied patch from PR bin/35408 by Andreas Wiese.
 - Use EXIT_FAILURE instead of 1.
 - Use return instead of exit() at the end of main().
 - Use sizeof() instead of BUFSIZ.

Missing config.h bring-in. Add for PR#24481

Remove unused code left over from temporary printescaped functionality.
Noted by Jeff Ito in PR bin/23966.

Overhaul how `build.sh tools' are used:

    *	Rename "config.h" to "nbtool_config.h" and
	HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
	This makes in more obvious in the source when we're using
	tools/compat/config.h versus "standard autoconf" config.h

    *	Consistently move the inclusion of nbtool_config.h to before
    	<sys/cdefs.h> so that the former can provide __RCSID() (et al),
    	and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
	#if HAVE_NBTOOL_CONFIG_H
	#include "nbtool_config.h"
	#endif
to the top of the source files (for the general case).

Following private discussion with kleink@ and hubertf@ and public discussion
on tech-userlevel@, back out printescaped() functionality.
kleink: ``We sell rope.''

Include "config.h" if building as a host program.
Need this to get SIZE_MAX defintion from compat_defs.h on FreeBSD.

This is a host tool, so for the time being change SIZE_T_MAX to the
more portable SIZE_MAX; partially addresses PR toolchain/22504 from
Christian Limpach.

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

Patches provided by Joel Baker in PR 22249, verified by myself.

As discusses a little while back on tech-userlevel:

If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.

While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.

Pull up revision 1.35 (requested by thorpej in ticket #793):
  Don't use MAX(); not all systems have it, and this is a host
  tool.

Don't use MAX(); not all systems have it, and this is a host tool.

Rather than (ab)using the standard error message for EFTYPE, print our own
message when "cat -f" is used on a non-regular file.  This is necessary to
make cat(1) portable to systems that don't have EFTYPE (like Linux).

Only use __RCSID() and __COPYRIGHT() if they're defined.

Pull up revision 1.32 (requested by mason in ticket #243):
Add -l option to cat(1), as discussed on tech-userlevel. This option
causes cat(1) to use fcntl(2) to set an exclusive advisory lock on stdout.
While being useful in its own right, this will shortly be used to
guarantee orderly writing to METALOG in the case of unprivileged builds
with NBUILDJOBS > 1.

Simplify previous - sbuf.st_blksize is a uint32_t, so just use
  bsize = MAX(sbuf.st_blksize, BUFSIZ);
and skip playing with SSIZE_MAX altogether.

Fix oversight in last.

Skip a check that is always true if _LP64 is defined.

pullup 1.19->1.20 (Juergen Hannken-Illjes)

Fix buffer allocation in function `raw_cat'. It was possible to get a
buffer size of zero if stdout has a block size of 0.
The command `rsh <host> cat <files>' gives no output and no error.

- Allocate a minimum of BUFSIZ bytes for buffer.
- Use a static buffer if either `fstat' or `malloc' fails.
- Do the allocation once since stdout will not change block size.

Patch from PR#5156 to adjust buffer size to match filesystem block size
when "-u" option used, plus some additional documentation.

Delint.

Pull up 1.16 and 1.17 (kleink)

Fix the EOL-indicators ('$') toggled by the `-e' option to be lined up
