Bugs fixed
* ``cython.view.array`` was missing ``.__len__()``.
* Extension types with a ``.pxd`` override for their ``__releasebuffer__`` slot
(e.g. as provided by Cython for the Python ``array.array`` type) could leak
a reference to the buffer owner on release, thus not freeing the memory.
* Auto-decoding failed in 0.26 for strings inside of C++ containers.
* Compile error when inheriting from C++ container types.
* Invalid C code in generators (declaration after code).
* Arithmetic operations on ``const`` integer variables could generate invalid code.
* Local variables with names of special Python methods failed to compile inside of
closures.
* Problem with indirect Emacs buffers in cython-mode.
* Extension types named ``result`` or ``PickleError`` generated invalid unpickling code.
* Bazel integration failed to compile ``.py`` files.
* Some include directories and dependencies were referenced with their absolute paths
in the generated files despite lying within the project directory.
