Renamed ckcksums -> ckdatacksums

Browse Source 
To clarify this only checks data reads, and to makes space for future
theoretical ck-operations:

- ckmetaredund - likely
- ckdataredund - unlikely, expensive
- ckmetacksums - unlikely, expensive
- ckdatacksums - implemented

This also tweaks the relevant mount/format/info flags a bit:

  LFS_M_CKPROGS       0x00100000 Check progs by reading back progged data
  LFS_M_CKFETCHES     0x00200000 Check block checksums before first use
  LFS_M_CKPARITY      0x00400000 Check metadata tag parity bits
  LFS_M_CKMETAREDUND+ 0x01000000 Check metadata redund blocks on reads
  LFS_M_CKDATAREDUND* 0x02000000 Check data redund blocks on reads
  LFS_M_CKMETACKSUMS* 0x04000000 Check metadata checksums on reads
  LFS_M_CKDATACKSUMS  0x08000000 Check data checksums on reads
