that removes the STATIC macro from MicroPython's C API.

A search suggests this PR might apply the STATIC macro to some C code. If it
does, then next time you rebase the PR (or merge from master) then you should
please replace all the `STATIC` keywords with `static`.

Although this is an automated message, feel free to @-reply to me directly if
you have any questions about this. """
