* public/private code untangled (smt/smt_engine.h no longer #includes

  expr/node.h).  This removes the warnings we had during compilation,
  and heads off a number of potential linking errors due to improper
  inlining of private (library-only) stuff in client (out-of-library)
  code.

* "configure" now takes some options as part of a "bare-option" build
  type (e.g., "./configure debug-coverage" or "./configure production-muzzle").

* split cdo.h, cdlist.h, cdmap.h, and cdset.h from context.h

* split cdlist_black unit test from context_black

* implement CDMap<>.

* give ExprManagers ownership of the context (and have SmtEngine share
  that one)

* fix main driver to properly report file-not-found

* fix MemoryMappedInputBuffer class to report reasons for
  "errno"-returned system errors

* src/expr/attribute.h: context-dependent attribute kinds now
  supported

* test/unit/expr/node_white.h: context-dependent attribute tests

* src/prop/cnf_conversion.h and associated parts of src/util/options.h
  and src/main/getopt.cpp: obsolete command-line option, removed.

* src/util/Assert.h: assertions are now somewhat more useful (in debug
  builds, anyway) during stack unwinding.

* test/unit/theory/theory_black.h: test context-dependent behavior of
  registerTerm() attribute for theories

* src/expr/node_builder.h: formatting, fixes for arithmetic
  convenience node builders, check memory allocations

* test/unit/expr/node_builder_black.h: add tessts for addition,
  subtraction, unary minus, and multiplication convenience node
  builders

* src/expr/attribute.h: more comments

* (various) code formatting, comment cleanup, added throws specifier
  to some destructors

* contrib/code-checker: prototype perl script to test (some) code policy

* contrib/indent-settings: command line for GNU indent to indent using
  CVC4 style (sort of; this is a work in progress)

* COPYING: legal stuff

* DESIGN_QUESTIONS: obsolete, removed
