Normal, Nonmutating, and Idempotent operations. Fixed bug introduced
into Freeze with previous changes for saving object state. (State
wasn't saved for idempotent operations.) Retested everything. I'm
getting a failure in the Yellow (C++) tests, and another failure in the
IceBox (Java) tests, but I don't think these are related to these
changes.

Changed Slice parser to reject identifiers beginning with "Ice", unless
the --ice option is used. Changed Slice parser to disallow identifiers
that have a trailing "Operations", "Holder", "Helper", "Prx", or "Ptr",
to avoid clashes with language mappings. Fixed tests and remaining code
base to work correctly with the changed rules.

Added code generation for Java constants to slice2java.
Added missing keyword (strictfp) to lists of keywords that need escaping
for Java.
Fixed bug in Java code generator: if a type name had a prefix in common
with the name of its enclosing scope, the scope mangling code stripped
off too much of the scope. For example:
enum color { red }; const color c = red;
This resulted in the generated type name being "olor" instead of "color"
because the constant starts with the same letter as the name of the
type.
Fixed bug in the keyword escape mechanism -- keywords embedded in scoped
names were not escaped.
Keywords escaping for both Java and C++ still has bugs. I wrote two Slice
torture files full of keywords. Neither the generated C++ code nor the
generated Java code work for those files yet. Need to look at this...

That way, we can check whether meaning changes as identifiers are
introduced into parameter declarartions.
Changes were quite extensive because one thing dragged another behind it...
Got rid of some of the pesky parse errors caused by returning zero from
some creation operations. In general, it seems easier to, whenever
possible, to create a dummy instance of something that doesn't quite
parse or doesn't quite get through a semantic check. This avoids
calling YYERROR, which can make a big mess of the scope stack. (I got
stuck on this for quite a long time before I figured out what was going
on.)
Took the opportunity to get rid of the awkward parsing for parameter lists.
We now have only a single parameters non-terminal, which simplifies
things (and also got rid of the one remaining shift/reduce conflict in
the grammar).
Updated all the code generators to work with the new structure for the
syntax tree.
Kept a rather ugly hack in Grammar.y to still permit use of semicolons to
indicate out params. This will go with stable_39, so I don't mind that
it's ugly for now.

keywords with a "_cpp_" prefix.
Changed Java code generator to use binary_search() instead of the
hand-coded binary search.

quite correct yet for enums and long long). The other code generators
(java, xsl, etc.) ignore constants for now. Semantic checks are in
place, apart from enums.
Still more work to do -- this is just an intermediate check-in. (About to
test this on Windows too...)
