[PATCH] variable instatiation support

[Samuel Rydh]

Hi,

This patch adds variable instantiation support. It is intended to
be used for device node instantiation.

Some implementational details:

- all template data is put into the dictionary. The thought behind this
is to make it possible to put both methods and template data in
a single wordlist.

- instantiated variables are stored in a continuous block of memory
(in contrast to the template data which is spread out in the dictionary).

A small example file is also attached to this e-mail.

Regards,
