In line to what is done in UFS, define an internal type
e2fs_lbn_t for the logical block numbers.
This change is basically a no-op as the new type is unchanged
(int32_t) but it may be useful as bumping this may be required
for ext4fs.
Also, as pointed out by Bruce Evans:
-Use daddr_t for daddr in ext2_bmaparray(). This seems to
improve reliability with the reallocblks option.
- Add a cast to the fsbtodb() macro as in UFS.

In the ext2fs driver we have a mixture of headers:
- The ext2_ prefixed headers have strong influence from NetBSD
and are carry specific ext2/3/4 information.
- The unprefixed headers are inspired on UFS and carry implementation
specific information.
Do some small adjustments so that the information is easier to
find coming from either UFS or the NetBSD implementation.
