reiserfsprogs: annotate for endian safeness

By annotating structure members and other on-disk structures as little
endian, we can catch bugs more easily.

The code was already endian safe except for three minor spots:
1) The badblock list code was initializing its key in an endian-unsafe way.
2) Indirect block pointer sequence printing was treating cpu-order values
   as little endian.
3) reiserfsck was trying to do endian switching on the lost+found key,
   but it was before it was even initialized to anything, so we can
   just remove that completely.

These issues were fixed as part of this commit.
