fc6ead4ac2 Improve match compilation of ? and fix bugs. 
- Coalesce repeated use of the same predicate.
- Fix scoring of Exact patterns, and scoring generally.
- Use `OrderedAnd` where needed.
- Guarantee that `and` patterns match in order.
- Thread bound variable information properly in GSeq compilation.
- Warn when variables are used non-linearly with `...`
  (making this behave properly was not backwards compatible).

Closes #952, which now runs in <1ms and make it a test case.

Also add margin note about `?` patterns and multiple calls.

c2cd44c928 Implement class sealing/unsealing 
Adds a sealing and unsealing function to attach (or detach)
seals onto a class via impersonator properties. Since these
properties override, they do not accumulate wrappers.

Calling seal multiple times will still accumulate multiple seal
values inside the property.

A sealed class cannot be instantiated and a subclass may not
add class members that match any of the sealed names in its
sealed parent.

These functions are intended for use by TR's `sealing->/c`
contract, but are parameterized over checking functions and
could be used for other purposes.

469763ca37 Adjust use of readtable argument in read/recursive 
Use the given readtable more consistently to parse
delimiters in the top-level form. This change particularly
addresses problems with trying to restore the original
`(` when parsing a hash table, but allowing nested
forms to still use a different `(` mapping.
