Considerably simplified the way output streams are used.  This commit
should have no impact on production performance and speed up debug
performance considerably, while making the code much cleaner.  On some
benchmarks, debug builds now run _much_ faster.

We no longer have to sprinkle our code with things like:

  if(debugTagIsOn("context")) {
    Debug("context") << theContext << std::endl;
  }

which we had to do to get around performance problems previously.
Now just writing:

  Debug("context") << theContext << std::endl;

does the same in production and debug builds.  That is, if "context"
debugging is off, theContext isn't converted to a string, nor is it
output to a "/dev/null" ostream.  I've confirmed this.  In production
builds, the whole statement inlines to nothing.  I've confirmed this
too.

Also, "Debug" is no longer a #definition, so you can use it directly
in production builds where you couldn't previously, e.g.

  if(Debug.isOn("paranoid:check_tableau")) {
    checkTableau();
  }

I'm leaving debugTagIsOn() for now, but marking it as deprecated.

With this commit come a number of changes to build system to support
building with CLN or with GMP, the contrib/switch-config script
(enabling "fast switching" of different configurations in the same
builds/ directory), and also some minor changes.

./configure --with-gmp     (or --without-cln) forces building with GMP
and doesn't even look for CLN.  Configure fails if GMP isn't installed.

./configure --with-cln     (or --without-gmp) forces building with CLN
and doesn't even look for GMP.  Configure fails if CLN isn't installed.

./configure [no arguments] will detect what's installed.  CLN is
default, if it isn't installed, or is too old, GMP is looked for (and
configure fails if neither is available).

It is an error to specify --with-gmp --with-cln (or --without-* for
both) at the same time.

Building with CLN (whether forced or detected) adds a note to the
configure output mentioning the fact that the build of CVC4 will be
linked against a GPLed library and notifying the user of the
--without-cln option.

Building with GMP (whether forced or detected) affects the build
directory, so CLN and GMP builds are kept separate.

./configure --with-cln debug     builds in builds/$arch/debug
./configure --with-gmp debug     builds in builds/$arch/debug-gmp

The final binaries are linked explicitly against either gmp or cln,
but not both.  If linked against cln, cln pulls in gmp as a
dependency, so the result will be linked against both.

=== Details that you probably don't care about ===

The headers src/util/{integer,rational}.h are generated from the
corresponding .in versions.  A user installing a CVC4-devel package
will get the headers for rational and integer that match the library
that s/he installs.

The preprocessor #defines CVC4_GMP_IMP and CVC4_CLN_IMP are added to
cvc4autoconfig.h.  Only one is ever #defined.  cvc4autoconfig.h
doesn't need to be #included directly; you get it through #including
cvc4_private.h (or the parser version).

AM_CONDITIONALs are also defined so that Makefiles get the cln/gmp
configuration.  AC_SUBSTs are defined so that public headers (see
src/util/{integer,rational}.h.in) can use the setting.

*Public* headers that need to depend on the cln/gmp configuration
can't use cvc4autoconfig.h, because we're keeping that in the private,
internal-only space, never to be installed on users' machines.  Here,
something special is required, like the configure-level generation of
headers that I used for src/util/{integer,rational}.h.in.

Tim's Integer and Rational wrappers are the only bits of code that
should care which library is used (and also src/util/configuration.h,
which gives the user of the library information about how CVC4 is
built), and possibly some unit tests (?).

To get this to work you will need to install cln in some form (for Ubuntu users the packages are libcln6(lucid)/libcln5 on karmic and libcln-dev).  You will also need to install pkg-config. You will need to rerun ./autogen.sh, and reconfigure.

* Convenience NodeBuilders (PlusNodeBuilder, OrNodeBuilder, etc.)

  This clears up a warning (private #inclusion) from the SMT and SMT2
