(1)
Combines the code paths for MAKE_FUNCTION and MAKE_CLOSURE.
Fixes a crash where functions with closures and either annotations or
keyword-only arguments result in MAKE_CLOSURE, but only
MAKE_FUNCTION has the code to handle annotations or keyword-only
arguments.
Includes enough tests to trigger the bug.

(2)
Change peepholer to not bail in the presence of EXTENDED_ARG +
MAKE_FUNCTION.
Enforce the natural 16-bit limit of annotations in compile.c.

Also update Misc/NEWS with the "input = raw_input" change.
