Lucas De Marchi 84f399ec3c APMrover2: Start using new Functor implementation
It both reduces flash size and move symbols to read-only sections.
The scheduler_tasks table is one known not to be in read-only section before due
to the FastDelegate implementation. Before and after this patch:

	APMrover2 $ size APMrover2.elf{.old,}
	   text	   data	    bss	    dec	    hex	filename
	 611406	   4832	  40920	 657158	  a0706	APMrover2.elf.old
	 609686	   4824	  38936	 653446	  9f886	APMrover2.elf

	APMrover2 $ nm -C APMrover2.elf{.old,} |grep tasks
	0000000000696f80 B Rover::scheduler_tasks
	000000000047c440 R Rover::scheduler_tasks

As can be seen above, now the scheduler_tasks symbol is in a read-only data
section and in all of them we decreased the total size.

For APM2 we have a similar situation, but the table was already in text section
because it was using plain C pointers:

	APMrover2 $ size APMrover2.elf{.old,}
	   text	   data	    bss	    dec	    hex	filename
	 189518	   1038	   3494	 194050	  2f602	APMrover2.elf.old
	 189216	   1038	   3480	 193734	  2f4c6	APMrover2.elf

	APMrover2 $ nm -C APMrover2.elf{.old,} |grep tasks
	00001f92 T Rover::scheduler_tasks
	00001f8a T Rover::scheduler_tasks
