coccinelle release 0.2.5

coccinelle release 0.2.5

** Language:
- Make a very small attempt to parse C++ code, amounting to accepting
  identifiers containing ::, tilde, and template invocations.  Use the
  option -c++.  This is not likely to be very useful in practice.
- Added metavariable metavariable type.
- Add disjunctions on identifiers in some contexts
- Pretend that & indicates a pointer in -c++ mode
- Support for new and delete
- Allow arrays in smpl parameter declarations.  Thanks to Jesper Louis
  Andersen for pointing out the problem.
- Field list metavariables
- Add the ability to add __attributes__ (NB, no matching on attributes)
- Slightly improved the error message for transformation on multiple
  variable declaration.  Thanks to Jonathan Nieder for pointing out the
  problem.

** Features:
- support transformations on variables (only) in declarations that declare
  multiple variables
- allow #endif XXX in C code
- relax_include_path now applied to non local includes too, in which case
  it tries to find a unique file with a suffix of the provided name.
  this is useful for directories that are intended to be symbolic links.
- support matching and removing #undef
- support for iteration in ocaml, requires use of -no_show_diff
- calls to likely and unlikely propagate test expression status to their
  arguments
- reuse typedefs and macros from complete parsing when reparsing the
  transformed code
- better explanation when presenting glimpse tokens
- optimization for an if branch that is just { ... }
- spatch -control_flow_to_file file.c generates a file file.dot
- include files with names ending in .cpp if -c++ option is given
- removed use of the no longer supported sexplib function Conv.hashtbl_of_sexp
- add information about which Fedora packages are needed

** Bugfix:
- improved parsing of expressions to allow ... to the right of operators in
  more places
- Fix check_config for Python 2.7 on Fedora 14 (Reported-by: Michael Stefaniuc)
- Check for ocamlfind in configure (Reported-by: Paul E. McKenney)
- Postpone use of ocamlfind at runtime to report fewer errors
- Add support for Python 2.4 binding with the provided pycaml library
- Allow '@' in script code.  Thanks to Laurent Reveillere for noticing the
  problem.
- Remove an optimization of x or true to true in asttoctl2 for the case
  where x may make a modification, eg the case of -thing ?-thing
- Allow adding comments before a function.
- Introduction of newlines in function arguments needs to take into account
  that the code added by SmPL can include newlines.  Thanks to Thomas
  Gleixner for finding the problem.
