btrfs-progs: sync file-item.h into progs 

This patch syncs file-item.h into btrfs-progs.  This carries with it an
API change for btrfs_del_csums, which takes a root argument in the
kernel, so all callsites have been updated accordingly.

I didn't sync file-item.c because it carries with it a bunch of bio
related helpers which are difficult to adapt to the kernel.
Additionally there's a few helpers in the local copy of file-item.c that
aren't in the kernel that are required for different tools.

This requires more cleanups in both the kernel and progs in order to
sync file-item.c, so for now just do file-item.h in order to pull things
out of ctree.h.
