[XFS] 929045 567344 This mod re-organizes some of the in-core file extent
code to prepare for an upcoming mod which will introduce multi-level
in-core extent allocations. Although the in-core extent management is
using a new code path in this mod, the functionality remains the same.
Major changes include: - Introduce 10 new subroutines which re-orgainze
the existing code but do NOT change functionality:
xfs_iext_get_ext() xfs_iext_insert() xfs_iext_add()
xfs_iext_remove() xfs_iext_remove_inline()
xfs_iext_remove_direct() xfs_iext_realloc_direct()
xfs_iext_direct_to_inline() xfs_iext_inline_to_direct()
xfs_iext_destroy() - Remove 2 subroutines (functionality moved to new
subroutines above): xfs_iext_realloc() -replaced by xfs_iext_add()
and xfs_iext_remove() xfs_bmap_insert_exlist() - replaced by
xfs_iext_insert() xfs_bmap_delete_exlist() - replaced by
xfs_iext_remove() - Replace all hard-coded (indexed) extent assignments
with a call to xfs_iext_get_ext() - Replace all extent record pointer
arithmetic (ep++, ep--, base + lastx,..) with calls to
xfs_iext_get_ext() - Update comments to remove the idea of a single
"extent list" and introduce "extent record" terminology instead
