glusterd: Use uint32_t for peerinfo generation number

Using a uint64_t for the peerinfo generation number was overkill for how
the generation number is used within GlusterD. It also prevented
GlusterD from running on 32-bit architechtures, as uatomic_add_return
doesn't support 64-bit values on 32-bit architechtures.

This change was developed on the git branch at [1]. This commit is a
combination of the following commits on the development branch.
  b78dba4 Use 32-bit generation number
  2c37e4b Change other generation number variables to uint32_t
