Merge from my post-smtcomp branch. Includes:

Dumping infrastructure.  Can dump preprocessed queries and clauses.  Can
also dump queries (for testing with another solver) to see if any conflicts
are missed, T-propagations are missed, all lemmas are T-valid, etc.  For a
full list of options see --dump=help.

CUDD building much cleaner.

Documentation and assertion fixes.

Printer improvements, printing of commands in language-defined way, etc.

Typechecker stuff in expr package now autogenerated, no need to manually
edit the expr package when adding a new theory.

CVC3 compatibility layer (builds as libcompat).

SWIG detection and language binding support (infrastructure).

Support for some Z3 extended commands (like datatypes) in SMT-LIBv2 mode
(when not in compliance mode).
