PR/32931: Johan Veenhuizen: cat(1) does not clear the EOF indicator for

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.

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.

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.

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.
