Introduce symbolic names for present and present & authenticated
...
A preloaded app can be:
- present and not yet authenticated (0x01)

Let's use symbolic names for these.

Add filesystem code and storage syscalls
...
Adds syscalls:
- ALLOCATE_AREA
- DEALLOCATE_AREA
- WRITE_DATA
- READ_DATA
and code to access the filesystem and the flash over SPI.
Based on original work by Daniel Jobson <jobson@tillitis.see> for
these files:
- auth_app.[ch]
- flash.[ch]
- spi.[ch]
- partition_table.[ch]
- rng.[ch]
- storage.[ch]
which are used with small changes to integrate with the new syscall
method.
