Major refactor to how printer methods work.

* Replaced define-unparser-method with define-print-method.  A print method is

  arguments and prints whatever it wants to.  The translation layer required by
  older unparser methods is no longer needed.

* New standard-print-method is roughly equivalent to simple-unparser-method.

* New bracketed-print-method is roughly equivalent to standard-unparser-method.

* Changed the printer to handle standard-print-method specially when detecting
  cycles and shared structure, so that an object using that print method has its
  parts walked when looking for shared/cyclic structure.

that implementation couldn't implement the tested behavior.

Rather than try to fix the implementation, I reverted hash-table-update! to its
previous implementation.  The rationale for this is that fixing the implementation
would effectively eliminate its performance advantage, while still being hard to

* Create new make-hash-table-type* which can create a type given an equality
  predicate and some keyword options.  If the equality predicate has registered
  properties, no additional options may be necessary, except perhaps to choose
  the entry type (which is specified by name).

* Change make-hash-table to accept the same options as make-hash-table-type* and
  to use the same defaulting.

* Change internal procedure follow-memo-crap to hash-metadata, which more
  accurately reflects its purpose: to get a properties table for the primary
  hash parameters.

Standardize hash tables on SRFI-69 names and deprecate others.

Change make-hash-table to be smarter about choosing the appropriate hash
function for a given equality predicate.

Also work around name collisions in rtlopt/rcse*.scm, and tweak the hash-table
implementation to favor SRFI-69.

Some work remains: the code around building hash-table types needs to be
re-thought: it's a little clunky and could usefully take advantage of keyword
arguments.  (These keyword arguments should also be supported by
make-hash-table.)  The hash function should be optional and use the
equality-predicate default.  The older %make-hash-table should be renamed and
exported as it's the right interface when using types.
