Fix the freaddir implementation for the stand-alone interpreter.

Bug pointed out by: Jan Beich <jbeich@tormail.org>

Fix the build of the testmain target. This target compiles a Forth
interpreter that can be run on the system and as such cannot be
compiled against libbstand. On the one hand this means we need to
include the usual headers for system interfaces that we use and
on the the other hand we can only use standard system interfaces.

While here, define local variables only when needed to make this
WARNS=2 clean on amd64.

Add 2 builtin words for working with directories:
isdir? ( fd -- bool )
freaddir ( fd -- ptr len TRUE | FALSE )

The 'isdir?' word returns `true' if the file descriptor is for a
directory and `false' otherwise.

The 'freaddir' word reads the next directory entry and if successful,
returns its name and 'true'. Otherwise 'false' is returned.

These words give the loader the ability to scan directories and read
files contained in them for 'rc.d'-like flexibility in handling which
modules to load and/or which tunables to set.

Remove Alpha bits for ficl.

Instead of just not defining a bunch of words when TESTMAIN is set, provide
stubs that at least handle the stack correctly. This makes it much easier to
experiment with loader scripts from userland.

Define 'arch-powerpc'

Set arch-pc98 env to true for pc98.

Fix for stand-alone compiling

Upgrade to FICL version 3.02. Anything wrong is my fault, everything right is

MFC after: 4 weeks

- Add 'fwrite' and 'fseek' words for writing to and seeking on files.
- Change the 'fopen' keyword to accept a mode parameter. Note that this
will break existing 4th scripts that use fopen. Thus, the loader
version has been bumped and loader.4th has been changed to check for a
sufficient version on i386 and alpha. Be sure that you either do a full
world build or install or full build and install of sys/boot after this
since loader.old won't work with the new 4th files and vice versa.

Add definition for arch-ia64.

Bring in ficl 2.05.

This version has a step debugger, which now completely replaces the
old trace feature. Also, we moved all of the FreeBSD-specific MI
code to loader.c, reducing the diff between this and the official
FICL distribution.

Only build PnP parts if the platform supports PnP.

Add the infrastructure necessary to handle PnP from a Forth script.

Also, export the file_findfile() function. Again, this is taken from
work in progress but frozen for the time being. Since it works, I'd
rather commit and remove any uglyness later than hide it on my tree.

Add setenv, getenv, setenv?, unsetenv, copyin and copyout to FICL.
