Foreign Function Interface for Python.
Initial motivation
------------------
http://mail.python.org/pipermail/pypy-dev/2012-May/009915.html
Current status
--------------
* works as a ctypes replacement
* can use internally either ctypes or a C extension module
Next steps
----------
the verify() step, which should handle:
* completing "...;" structs
* checking the other structs, and the arguments to functions, using the real C compiler
* simple "#define FOO value" macros
* macros of the kind "#define funcname otherfuncname"
* more complicated macros "#define foo(a, b, c) ..."
* checking and correcting the value of the enum {} declarations
* probably also fixing the array lengths, e.g. declared as a field "int foo[...];"
generating C extensions:
* this is needed anyway to call macros
* faster, libffi-free way to call C code
* partial blockers: callbacks (probably still use libffi)
