Support dependencies in conditional compilation

Adds support for simple FakeReference equality testing.

setup.py shouldn't write arbitrarily to stdout (especially when passed display options)

In general it's best for actions performed in `setup.py` to be deferred until the command to which they are relevant is actually run.  For example most of what `compile_cython_modules` does should be deferred until finalizing the `build_ext` command.  But as a simpler workaround, just ensure that anything it prints is to stderr.

Otherwise this breaks certain assumptions, such as that `./setup.py --name` will print (on stdout) the distribution name (and nothing else), and likewise for `./setup.py --version`.

Cython.Build brings in cythonize, which is not in a Py3.2 compatible file.

Fix overriding of cdef by cpdef method in .pxd file

Repair calls to fused staticmethods : we currently generate the wrong C signature for them (first arg becomes 'self' arg), so this change works around that by really passing the first argument as 'self'.
Eventually, ths signature should be fixed instead.

restrict "__dict__" property generation to declared "__dict__" attributes and ignore everything else

Closes #531.

Closes github issue #1447.

let pcython script parse the main script arguments and pass them on instead of incorrectly rejecting them as unknown

repair accidental change in macro usage (used to be CPYTHON, was accidentally changed to PYPY in a previous commit)

disable self-argument extraction for lambda functions to revert to old "self in args" argument parsing behaviour

re-enable "profile" and "linetrace" directives at class/function level to allow switching it on and off for specific code sections

Use global constants for default arguments of cpdef functions/methods and def methods in cdef classes as using the CyFunction defaults requires passing the CyFunction as self (which we currently don't do for methods in cdef classes).
Properly fixing this requires changing the call signature of CyFunction.

use global constants for default arguments of cpdef functions (which are static C functions internally)
