cleanup: remove some unnecessary input.[ch] typedefs

Remove some unnecessary typedefs and remove pointless mp_ prefix from
some internal struct names.

Change the type of the "close_func" pointers from "void f(int fd)" to
"int f(int fd)" so that using standard close() there is valid.

Delete some useless assert() statements.

Move internal MP_MAX_KEY_DOWN define from input.h to input.c.
