* Add the c_init_default attribute which is used to initialize the C variable
if the default is not explicitly provided.
* Add the c_default_init() method which is used to derive c_default
from default if c_default is not explicitly provided.
* Explicit c_default and py_default are now almost always have precedence
over the generated value.
* Add support for bytes literals as default values.
* Improve support for str literals as default values (support non-ASCII and
non-printable characters and special characters like backslash).
* Improved support for default values in converters "char" and
"int(accept={str})".
* Add support for non-NULL default values in converter "Py_buffer".
* Improve error handling for invalid default values.
