[PATCH 0/2] Remove v0 extent support

[Nikolay Borisov <nborisov@suse.com>]

It's unlikely there is anyone using that or even if they are they have bigger 
problems than this patchset :). After all, v0 was introduced 9 years ago and 
it was already conditionally compiled by the time BTRFS was merged in the
upstream kernel. The patches themselves are really simple - patch 1 removes 
all the code within ifdef guards. Patch 2, in turn, ads graceful handling by 
aborting transaction where it makes sense or calling btrfs_handle_fs_error and 
printing an informative error message.
