This patch adds the format string characters a, A and F to the
supported set of the built-in printf command. They're already
supported by the underlying printf function.

Here's a slightly tweaked version of that patch. Regardless of whether
PRIdMAX is defined as "jd" or as "lld", the use of memcpy here, first
copying "jd"/"lld" and the null byte, and only changing the 'd' after
that, surprisingly results in slightly shorter object code than the
original byte-by-byte approach, even though memcpy is fully inlined.
Perhaps that could be a reason for applying this, even if the original
reason for it, making the code work on not-quite-conforming systems,
isn't good enough to get it in dash.
Tested with normal glibc, and with glibc hacked to not provide PRIdMAX.

The patch to make outc into an inline function created an unnecessary
promotion in echocmd due to its use of char vs. the int used by outc.
This patch changes echocmd to use int instead.

Instead of setting rval when \c is detected, this is now set in the
return value of conv_escape_str. This prevents the spillage reported
in http://bugs.debian.org/337294.

Instead of calling conv_escape_str when we detect a backslash we will call it
unconditionally. This helps get rid of some unnecessary code in echocmd.

The support for standalone/csh printf only serves to complicate
maintainence.

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.
