This was found by the logfs unit tests.
This may be useful if we want to use empty files as existence
flags in the future. Doesn't make any sense for UAVOs but
is valid in the general sense of a filesystem.
Verify that the flash component on the board matches exactly
what we're expecting. This is a simple way to verify that we
are communicating properly with the JEDEC flash chip.

When storing an opaque pointer value in a uint, the
appropriate type is uintptr_t which is guaranteed to
be wide enough to hold a pointer.
This is particularly important when the code can be
compiled in a sim or unit test environment which is
intended to run on a 64-bit machine.

Build it with:
make ut_logfs
Create a raw flash file like this:
dd if=/dev/zero bs=1 count=2MiB | tr '\000' '\377' > theflash.bin
Run it with:
./build/unit_tests/logfs/logfs.elf && echo 'all good'

The flashfs layer is now entirely decoupled from the UAVO
data types. All UAVO related calls are now properly
contained within uavobjectmanager.c.
This will make the flashfs layer more portable as well as
more testable in a standalone environment. Eventually,
this layer could be used to store arbitrary files.
Also fixed all of the doxygen headers for the flashfs API.
A new flash driver abstraction is also provided to allow
for future support of other types of flash device under
the filesystem.

the error is shown as a number of slow flashes followed by 10 fast flashes.
The number of slow flashes indicate the error code:
1 - Self overwrite check failed;
2 - Board hardware revision mismatch;
3 - Flash erase failed;
4 - Flash programming failed;
The error code sequence will be shown indfinitely should a error occurs.
