this new information to correctly resolve destination (b<mark) references. See the email archives for further discussion on why
this is required.
Hopefully this should finally resolve the Fcode backward branch problem; at least all previous incorrect resolutions now appear
correct and the Fcode evaluator no longer crashes or gets stuck in a loop while attempting to boot Milax.

According to the specification, the destination for a backwards Fcode branch must be resolved from the bottom rather than the
top of the cstack. The existing version of the code was simply doing a swap, and so nesting any branches within a backward branch
would fail since the wrong destination would be resolved from the stack.
This patch adds a new cstack-startdepth variable to keep track of the cstack base location within an execution context
(setup-tmp-comp and execute-tmp-comp) and alters the backward branches to make use of it.
With this patch in place, Milax under Qemu doesn't crash anymore but sits in an infinite loop reading sectors from the CDROM.

simpler version s" that does not contain a complex parser for
" "(0a) type of strings.
Also use handle-text in " instead of the hand crafted version. This fixes
strings in "see".

This patch implements the following Forth words:
debug <xt> - Mark word for debugging
debug-off - Unmark all words for debugging
resume - Return from subordinate Forth interpreter
The source debugger also implements the following commands when it has
been activated:
Up - Unmark current word for debugging, mark parent and continue
Down - Mark next word for debugging
Trace - Continue execution until end of word displaying
debug information
Rstack - Display contents of the Rstack
Forth - Launch subordinate Forth interpreter

This changes pocket index calculation to support more than two pockets.
As an example default number of pockets is set to 4.
This should ease nesting more than two levels using pockets as
temporary storage.
