state: remove checks for xzalloc() returning NULL ...

|
|     remove checks for xzalloc() returning NULL
|
|     xzalloc() either returns memory or panics, so checking for NULL is useless.

barebox-state: backend_raw: init digest earlier ...

In backend_format_raw_pack() digest_length is used before it's
initialized in backend_raw_digest_init() which results in a too small
memory allocation for the raw backend. Fix this and prevent a memory
corruption.

state: Allow to load without authentification ...

Sometimes it's useful to be able to load a state even when it
can't be authentificated. Add an option for this.

state: backend_raw: alloc digest only when needed ...

Instead of deferring probe just allocate the digest when
it's needed. This way the credentials can be added later,
possibly on the commandline.

state: Convert all bufs to void * ...

A void * is a much better type for a buffer than a u8 * as it
can be casted to any other type implicitly. Convert all buffers
used by the state framework to void *.

state: replace len_hint logic ...

The len_hint mechanism is rather hard to understand as it's not clear
from where to where the hint is passed and also it's not clear what
happens if the hint is empty or wrong.

state: use packed attribute for on storage structs ...

These structs are used for on-storage data layouts. They should be not
affected by different integer precisions and alignment optimizations of
32bit or 64bit machines. Using the architecture independent integer data
types, like uint32_t, achieves the former, using the packed attribute
the later.

barebox-state: Add force switch ...

The force switch allows to read from a state even when the
