This patch improves LINENO support by storing line numbers in the parse
tree, for commands as well as for function definitions. It makes LINENO
behaves properly when calling functions, and has the added benefit of
improved line numbers in error messages when the last-parsed command is
not the last-executed one. It removes the earlier LINENO support, and
instead sets LINENO from evaltree when a command is executed

At some point between ash 0.3.5-11.0.1 and ash 0.3.8-37, Debian
ash stopped using the EXSHELLPROC exception to handle shell
scripts without a magic number.
Remove all remaining references to it to avoid confusion.

The intended semantics of EXEXEC are identical to EXEXIT, so
simplify by using EXEXIT directly.
Functional change: in edge cases (exec within a trap handler),
this causes the exit status from exec not to be clobbered.
For example, without this patch:
$ sh -c 'trap "exec nonexistent" EXIT'; echo $?
exec: 1: nonexistent: not found
0
And with it:
$ sh -c 'trap "exec nonexistent" EXIT'; echo $?
exec: 1: nonexistent: not found
127

Now that waitcmd no longer uses EXSIG we can remove it.

This is the only instance of __P in the entire source so it makes sense
to get rid of it rather than making it work with klibc.

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.
