- Try to do better pretty printing when array elements are individually

- Try to do better pretty printing when array elements are individually
  replaced
- Just fail quietly on attempt to remove a multi-variable declaration,
  allowing the semantic patch to continue.  A warning message is printed.
- Ignore unknown identifiers around known types.
- Ignore --use-glimpse if multiple directories given
- Added support for c++ namespace syntax in cocci files.
- use arg_expression for printing iterator arguments instead of expression,
  to get the right spacing.  Thanks to Lars-Peter Clausen for the fix.
- Better spacing for generated argument lists.  Thanks to Lars-Peter Clausen
  for reporting the problem.
- Collect all module interfaces for ocaml scripting in a single
  coccilib.cmi file, with the list of exposed internal modules in
  ocaml/exposed_modules.ml. This simplifies the installation of the
  ocaml version of coccilib, and allows us to specify which modules
  can be accessed by an ocaml script. The coccilib.cmi must either
  reside in $COCCI_DIR/ocaml/ or $COCCI_DIR/ocaml/coccilib/.
- Ocamlbuild-based compilation of coccinelle (experimental). In a
  cleaned repository, use the configure option --enable-ocamlbuild to
  enable it. The Makefiles will then use ocamlbuild.
- Ocamlscripts can access more of coccinelle: the file
  ocaml/exposed_modules.ml specifies which modules are accessible.
- Use arg_expression to print macro arguments.  Thanks to Lars-Peter
  Clausen for the fix.
- Remove some trailing whitespace due to unindent or added if braces.
  Thanks to Eric LeBlond for reporting one of the problems.
- Remove undesired newline after if header when body is a metavariable.
  Thanks to Eric LeBlond for reporting the problem.
- Improve macro expansion to take into account variable numbers of
  arguments
- Don't count macros or ifdefs in counting fields
- Better counting of indent size when indent contains multiple tabs
- Get the right annotation on trailing , that is after a nest.  Requires
  avoiding double processing in transformation_c.ml
- Fixed an issue where an 'Impossible' exception could be raised.
- Fixed an issue where some identifiers were incorrectly interpreted as typedef.
