Support presence of __attribute__ in function declarations

[gmills-qti]

I have a function declared like so that is not getting detected.

int foo(char *bar) __attribute__((nonnull(1)));

I played with the c_parser.py (0.1.2 from pypi) and got this to work. I ported to tip from github.

         # Struct definition

If there is another way to do this with extra_modifiers, let me know.

Nevermind. Figured it out.

CParser(..., replace={r'__attribute__.*;' : ';'}, ...)

I will try to see if we can add a permanent fix. Thanks for reporting.
