MEM_OUT is only used by forkless backtick processing which we do
not currently support.

The branch in outmem where the string fits in the buffer is the
common case and is now marked as likely.

This patch fixes handling of embedded NULs using an approach similar
to the one taken by NetBSD. In particular, we first determine the
length of the output string, and then use a sequence of Xs of the
same length as input to the underlying C printf to determine the
amount of leading and trailing padding. Finally we replace the
Xs with the actual string before writing it out.
In order to print out the temporary string containing Xs and padding,
a new helper xasprintf is added. Unlike asprintf though, our
xasprintf prints to the ash stack rather than using straight malloc
memory.

- Solaris lacks paths.h and the various _PATH_* #defines.
Check for them in configure.ac and fall back on the
usual suspects when they are missing.
- Older Solaris lacks isblank(), and versions that have it
use a macro. Check for the declaration in configure.ac
and fall back on a naive version when missing.
- Older Solaris does not support %jd (intmax_t) in format
strings, but it does support the PRIdMAX macro from inttypes.h.
Do a configure check for PRIdMAX and use it in the code.
If it doesn't exist, define it to "lld" when sizeof(long long)
equals sizeof(intmax_t) as this is more likely to work on
older systems. Otherwise, use "jd" and hope for the best.
- Older Solaris lacks stdint.h, but inttypes.h provides the
same types and works on all platforms I've tried dash on,
so just use it instead.
- Older Solaris doesn't like it when vsnprintf() is passed
a NULL buffer (in violation of the POSIX spec, of course).
Pass a 1-byte dummy buffer instead.
- Solaris lacks tempfile and mktemp programs. Fall back on a
"good-enough" custom function in mkbuiltins.

All users of mempcpy must include system.h.

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.
