fw: UDS not byte-readable
Since UDS is not byte-readable we copy it by word to local_uds. Now
UDS lives for a short while in local_uds on the stack in FW_RAM and in
the internal buffer of the blake2s context (also in FW_RAM) but is
very soon overwritten.

fw: clang-tidy and splint: New make target: check
Add clang-tidy and splint static analytics check. For now, we use only
the cert-* warnings on clang-tidy and run splint with a lot of flags
to allow more things.

Changes to silence these analytics:

- Stop returning stuff from our debug print functions. We don't check
  them anyway and we don't have any way of detecting transmission
  failure.

- Declare more things static that isn't used outside of a file.

- Change types to be more consistent, typically to size_t or
  something or to uint32_t.
