Neither of these actually need the root argument, we provide all the
information for the ref through the arguments we pass through. Remove
the root argument from both of them. These needed to be done in the
same patch because of the __btrfs_mod_ref helper which will pick one or
the other function for processing reference updates.

This is a bit larger than the previous syncs, because we use
extent_io_tree's everywhere. There's a lot of stuff added to
kerncompat.h, and then I went through and cleaned up all the API
changes, which were
- extent_io_tree_init takes an fs_info and an owner now.
- extent_io_tree_cleanup is now extent_io_tree_release.
- set_extent_dirty takes a gfpmask.
- clear_extent_dirty takes a cached_state.
- find_first_extent_bit takes a cached_state.
The diffstat looks insane for this, but keep in mind extent-io-tree.c
and extent-io-tree.h are ~2000 loc just by themselves.

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.

While syncing messages.[ch] I had to back out the ASSERT() code in
kerncompat.h, which means we now rely on the kernel code for ASSERT().
In order to maintain some semblance of separation introduce UASSERT()
and use that in all the purely userspace code.

From the very beginning of free-space-tree feature, we allow mount
option "space_cache=v2" to convert the filesystem to the new feature.
But this is not the proper practice for new features (no matter if it's
incompat or compat_ro).
This is already making the clear_cache/space_cache mount option more
complex.
Thus this patch introduces the proper way to enable free-space-tree, and
I hope one day we can deprecate the "space_cache=" mount option.

Currently check/clear-cache.c still uses a lot of global variables like
gfs_info and g_task_ctx, which are only implemented in check/main.c.
Since we have separated clear-cache code into its own c and header files,
we should not utilize those global variables.
Or it would lead to compiling errors for any tools which only has
check/clear-cache.o linked:

This provides the basis for later clear cache usage out of check realm.
