Instead of detecting EOF using the input layer, I'm going to
use the parser instead. In either case, we always have to read
ahead in order to complete the parsing of the previous node.
Therefore we always know whether there is more to come, except
in the case where we see a newline/semicolon or similar.
For the purposes of sh -c, this should be sufficient.

The file arith_yacc.h was missing from dash_SOURCES causing it
to be excluded from the generated tar file.

Debian's libc6 as of 2.6.1-6 has working glob(3)/fnmatch(3) support.
This patch adds the options --enable-glob and --enable-fnmatch to
the configure script. By default glob(3) and fnmatch(3) are still
unused. However, on distros where the glibc is known to work you
may enable these options.

This patch adds assignment operator support in arithmetic expansions. It
also changes the type used to intmax_t.

Add to the configure.ac new option:
--with-libedit - Compile with libedit support.

For systems without getrlimit (e.g., klibc) we will disable ulimit.
In order to achieve this, builtins.def is now produced by cpp which
allows us to use macros such as HAVE_GETRLIMIT in it.
Thie also means that we can get rid of the cflags parsing code in
mkbuiltins.

This change updates the BSD licence to the three-clause version since
NetBSD has already done so. This makes dash GPL-compatible.
It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file.
I've added "copyright by Herbert Xu" to most files.
Finally all CVS IDs and inclusion of sys/cdefs.h have been removed.
The latter is needed for support of klibc.
