[avr-libc-dev] [RFC] Generate compiler warning if not included from avr/

This patch adds a simple check to each ioXXX.h file to see if the file was
included directly or via avr/io.h.

The second check is to verify that one and only one ioXXX.h file has been
included. This catches the case where a user does something foolish as
such (assume -mmcu=at90s8515):

  #include <avr/io.h>
  #include <avr/iom128.h>

This is the first step in moving redundant code from ioXXX.h to io.h
