- Added the comment module to the theories.pdf ("make latex").

- Added a hack allowing to override a theory display with another theory's
display. This is necessary for bootstrapping reasons - it allows one
to get a reasonable output of a theory (e.g. Comment) that is defined before
all essential display forms (e.g. the Summary ones) are there.

- Added debugging code to make it easier to find dforms that cause
zone begin/end mismatch (and used it to get rid of all
the "Unballanced buffer" warnings in "make latex").

- Minor dforms&comments updates.

I am committing David Bustos' changes to the cons build system for Metaprl.

Code cleanup:

I looked (using the code I've put into macro.ml) for places where the same code
appeared in several branches of a match or function expression. I changed those
places to use a complex pattern and a single copy of the code.

- Merged the Ocaml 3.02 changes

- Now http server is compiled in by default, but is only started if
the "-http true" argument is passed or MP_HTTP environment variable
is set to "true".

- A few other minor changes.

*** IMPORTANT: before doing "cvs update" see warning below ***

This commit implements a global resource that brings together resource management
that used to be done by each resource in its own way.

- A much simplier object (Mp_resource.resource_info) is now needed to create a new resource.
Additionally, many resource helper modules, such as term_match_table now provide functions
that create a resource_info for you.

- Funtions get_tactic_arg, get_int_tactic_arg, etc were replaced by a single function
get_resource_arg (note: functions for basci types, such as get_with_arg, get_sel_args, etc
were _not_ affected)

- Resource declaration statement now declares and resource creation statement now creates
a function get_<name>_resource. This function ca be passed as a second argument
to get_resource_arg to retrieve the current value of a particular resource.

- Resource annotation functions are now separate from the resource declaration/creation
mechanism. Resource annotation on a rule are now passed to a function named
process_<name>_resource_annotation. This function must have the appropriate
Mp_resource.annotation_processor type for the resource. This function can be declared
and implemented in _any_ module, not just the module that declares and creates the
<name> resource.

- Currenlty MetaPRL leaves it to Ocaml to keep track of these functions.
Consequently the module that defines the process_<name>_resource_annotation function
must be open'ed (not included!) by modules that use <name> annotations.


Unfinished business in this commit:
- Remainder of TODO 1.12 and 1.13

- Some proofs were broken by this commit. It appears that they were broken for
a "good" reason, but still need to be fixed.

- I need to make sure things now always have the right precedences (all things being equal,
the later an item is added to resource, the earlier precedence it should have).

- Consider adding refiner sentinels and display forms to global resource as well.
Currently each of them still does its own way of resource management (although the way
display forms are managed was changed by this commit - need to make sure the precedences
are right).

- Distributed refinement: I am afraid that the current resource code
will either work correctly only if all processes in the distributed group have
the same global resource, or it will attempt to pass around all the resource data.
Obviously, neither of these choices is a good one.

*** WARNING ***

This commit changes the tactic_arg type and also makes minor changes in
the FilterCache.info type. Because of that old .prlb and .cmoz files
*will no longer work*. Old .prla files will work, but will produce lots
of (harmless) Filter_summary.dest_term warning.

Before doing "cvs update" do the following:
1) export all your unsaved proofs into .prla files.
2) rm -f theories/*/*.prlb
3) run "make clean"

 - Fixed a nasty bug in Term_ds.subst - it didn't notice when the same variable
was mentioned several times in the substitution with different terms substituted
for it. This made it possible to break Term_ds invariants leading to all kinds of
strange behaviour.

 - Changed the argument order for "subst" to be more natural

 - Added a subst1 function to substitute for a single variable without having
to put the substitution into a singleton list.

 - Added the resource annotations and updated the rest of the resource code
in CZF so that it now compiles (but I didn't try to expand anything).

Enabled the "strict" rewriter mode.

In "strict" mode, <<lambda{x.'t}>> will only match terms where "t" does not contain
free occurences of "x" while <<lambda{x.'t['x]}>> will match any lambda expression.
In "relaxed" mode both redices will match any lambda expression.

This is done
1) To force rule authors to completely specify the binding structure
2) To allow rule authors to specify free variables restrictions easier

refiner/refiner/refine.ml, filter/boot/rewrite_boot.ml and theories/tactic/tactic_cache.ml
use the strict mode.

filter/base/filter_prog.ml uses relaxed mode for d.f. and compiles ml rewrites
using the strict mode

refiner/reflib/dform.ml, refiner/reflib/term_dtable.ml and refiner/reflib/term_match_table.ml
use the relaxed mode.

Please let me know if this change breaks something.

I changed all the obvious places of Nuprl-Light, NL, nl, or any
other instance to MetaPRL, MP, or mp, etc.  The docs may be broken
but I'll fix them soon.  As usual, let me know if anything breaks.

Added license headers to each of the files in preparation for
the first major release.  The license is GNU public license; if
any of you have problems with that, let me know right away.  When
you add new code, you should credit yourself as the author.  When
you modify code, you should add a "Modified by:" to the header,
and possibly a short summary of your changes.

I tried to get the Author lists as correct as I remember, but there
are more than 550 files(!) and I may have made some mistakes. Please
add yourself if I didn't do it right.
