Allow strerror(0) and strerror_r(0, ...).

Of course, strerror_r() may still fail with ERANGE.

Although the POSIX specification said this could fail with EINVAL and
doing this likely indicates invalid use of errno, most other
implementations permitted it, various POSIX testsuites require it to
work (matching the older sys_errlist array) and apparently some
applications depend on it.

Add a new errno, ENOTCAPABLE, to be returned when a process requests an
operation on a file descriptor that is not authorized by the descriptor's
capability flags.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Add some missing errnos from POSIX. Nothing in FreeBSD generates
these at the moment, but applications that test for them will now
have a better chance of compiling.

I have intentionally omitted errnos that are only good for STREAMS,
since apps that use STREAMS won't compile anyway. The exception is
EPROTO, which was apparently intended for STREAMS, but worth having
anyway because Linux (mis)uses it for other things.

Drop almost 3k from /bin/sync by moving errno to a seperate file
to avoid all syscalls pulling in sys_errlst[].

Introduce a new error return code:
#define EDOFUS 88 /* Programming error */
This can be used to signal error situations which indicate that the
program logic or assumptions is deficient.

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

Add new errno ``ENOATTR''.

Add missing strings.
