We don't have these defined in the kernel because we don't have any
users of these helpers. However we do use them in btrfs-progs, so
define them to make keeping accessors.h in sync between progs and the
kernel easier.

We already have this defined in btrfs-progs, add it to the kernel to
make it easier to sync these files into btrfs-progs.

This is simply the same thing as btrfs_item_nr_offset(leaf, 0), so
remove this helper and replace it's usage with the above statement.

This is a change needed for extent tree v2, as we will be growing the
header size. This exists in btrfs-progs currently, and not having it
makes syncing accessors.[ch] more problematic. So make this change to
set us up for extent tree v2 and match what btrfs-progs does to make
syncing easier.

This is actually a change for extent tree v2, but it exists in
btrfs-progs but not in the kernel. This makes it annoying to sync
accessors.h with btrfs-progs, and since this is the way I need it for
extent-tree v2 simply update these helpers to take the extent buffer in
order to make syncing possible now, and make the extent tree v2 stuff
easier moving forward.

These got moved because of copy+paste, but this code exists in ctree.c,
so move the declarations back into ctree.h.

These helpers use functions that are in multiple places, which makes it
tricky to sync them into btrfs-progs. Move them to file-item.h and then
include file-item.h in places that use these helpers.

This is only used in ctree.c, with the exception of zero'ing out extent
buffers we're getting ready to write out. In theory we shouldn't have
an extent buffer with 0 items that we're writing out, however I'd rather
be safe than sorry so open code it in extent_io.c, and then copy the
helper into ctree.c. This will make it easier to sync accessors.[ch]
into btrfs-progs, as this requires a helper that isn't defined in
accessors.h.

These accidentally got brought into accessors.h, but belong with the
btrfs_root definitions which are currently in ctree.h. Move these to
make it easier to sync accessors.[ch] into btrfs-progs.

For directories with encrypted files/filenames, we need to store a flag
indicating this fact. There's no room in other fields, so we'll need to
borrow a bit from dir_type. Since it's now a combination of type and
flags, we rename it to dir_flags to reflect its new usage.
The new flag, FT_ENCRYPTED, indicates a directory containing encrypted
data, which is orthogonal to file type; therefore, add the new
flag, and make conversion from directory type to file type strip the
flag.
As the file types almost never change we can afford to use the bits.
Actual usage will be guarded behind an incompat bit, this patch only
adds the support for later use by fscrypt.

This is a large patch, but because they're all macros it's impossible to
split up. Simply copy all of the item accessors in ctree.h and paste
them in accessors.h, and then update any files to include the header so
everything compiles.

This is specific to the item-accessor code, move it out of ctree.h into
accessor.h/.c and then update the users to include the new header file.
This un-inlines btrfs_init_map_token, however this is only called once
per function so it's not critical to be inlined. This also saves 904
bytes of code on a release build.
