There are many cases where functions take pointers to keys, item heads,
paths, etc and don't modify them. Let's annotate them properly.

There are many calls in which strings are passed as "char *" yet aren't
modified. This patch marks them const so callers can depend on it.

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.

The upstream kernel got rid of the per-endian implementations of
the offset_v2 helpers in favor of explicitly accessing by little
endian bitranges.

reiserfs_invalidate_buffer contains an argument to specify whether a block
should be freed after being invalidated. It is always passed as 1, so
let's just get rid of it.

We open code buffer_info initialization all over the place. Let's
factor that out so we don't reproduce the code everywhere.

This patch does a quick search and replace:
B_N_PITEM_HEAD() -> item_head()
B_N_PDELIM_KEY() -> internal_key()
B_N_PKEY() -> leaf_key()
B_N_PITEM() -> item_body()
And the item_head version:
B_I_PITEM() -> ih_item_body()
I_ENTRY_COUNT() -> ih_entry_count()
And the treepath variants:
get_ih() -> tp_item_head()
PATH_PITEM_HEAD() -> tp_item_head()
get_item() -> tp_item_body()
... which makes the code much easier on the eyes.

Over the years, the reiserfs kernel code has been gradually cleaned up
to be more readable. This patch does the same to the progs code.

In order to convert reiserfscore into a externally-usable library,
we need to rename structures so they won't collide with other
namespaces.

Now that we handle file systems > 8 TB, we end up printing large negative
numbers instead of actual block numbers. This patch fixes those places
to use unsigned ints for block numbers.
