[PATCH 0/3] MR1536: Preparation to long types migration (serie II)

[eric pouech (＠epo)]

Migration a couple of bits to unsigned int.

Note to Zebediah (mainly on second commit of this serie):
- there is also a load of 'uint32_t flags' parameters that I didn't change
  (mainly not to change too many things)
  Is this something to consider?
- I didn't touch the local variables either.
  Maybe it's something to consider also.
