Clean up ada-lang.h

This patch cleans up ada-lang.h:

- Some functions just don't exist anymore, remove their declaration
- Some functions are implemented in ada-lang.c and only used there, make
  them static to that file.

I moved some functions higher in the file to avoid having to
forward-declare them, but the implementations are unchanged.

gdb/ChangeLog:

	* ada-lang.h (GROW_VECT): Move to ada-lang.c.
	(grow_vect): Remove declaration.
	(ada_type_of_array): Remove declaration.
	(ada_update_initial_language): Remove declaration.
