The net value of these functions is to determine the result of a
three-way-comparison between operands of the same type.

Simplify the code using cmp_int() to eliminate potential errors with
opencoded casts and subtractions. This also means we can change the return
value type of cmp_key_with_cur routines from int64_t to int and make the
interface a bit clearer.

key_diff routines compare a key value with a cursor value. Make the naming
to be a bit more self-descriptive.

One may think that diff_two_keys routines are used to compute the actual
difference between the arguments but they return a result of a
three-way-comparison of the passed operands. So it looks more appropriate
to denote them as cmp_two_keys.

Replace the pag pointers in the type specific union with a generic
xfs_group pointer.  This prepares for adding realtime group support.

<content type='text'>
Split busy extent tracking from struct xfs_perag into its own private
structure, which can be pointed to by the generic group structure.

Note that this structure is now dynamically allocated instead of embedded
as the upcoming zone XFS code doesn't need it and will also have an
unusually high number of groups due to hardware constraints.  Dynamically
allocating the structure this is a big memory saver for this case.

<content type='text'>
Split the lookup and refcount handling of struct xfs_perag into an
embedded xfs_group structure that can be reused for the upcoming
realtime groups.

It will be extended with more features later.

Note that he xg_type field will only need a single bit even with
realtime group support.  For now it fills a hole, but it might be
worth to fold it into another field if we can use this space better.

Standardize the parameters in xfs_{alloc,bm,ino,rmap,refcount}bt_maxrecs
so that we have consistent calling conventions.  This doesn't affect the
kernel that much, but enables us to clean up userspace a bit.
