xfs: encode the btree geometry flags in the btree ops structure

Certain btree flags never change for the life of a btree cursor because
they describe the geometry of the btree itself.  Encode these in the
btree ops structure and reduce the amount of code required in each btree
type's init_cursor functions.  This also frees up most of the bits in
bc_flags.

A previous version of this patch also converted the open-coded flags
logic to helpers.  This was removed due to the pending refactoring (that
follows this patch) to eliminate most of the state flags.

Conversion script:

sed \
 -e 's/XFS_BTREE_LONG_PTRS/XFS_BTGEO_LONG_PTRS/g' \
 -e 's/XFS_BTREE_ROOT_IN_INODE/XFS_BTGEO_ROOT_IN_INODE/g' \
 -e 's/XFS_BTREE_LASTREC_UPDATE/XFS_BTGEO_LASTREC_UPDATE/g' \
 -e 's/XFS_BTREE_OVERLAPPING/XFS_BTGEO_OVERLAPPING/g' \
 -e 's/cur->bc_flags & XFS_BTGEO_/cur->bc_ops->geom_flags \& XFS_BTGEO_/g' \
 -i $(git ls-files fs/xfs/*.[ch] fs/xfs/libxfs/*.[ch] fs/xfs/scrub/*.[ch])
