These are the printk helpers from the kernel. There were a few
modifications, the hi-lights are
- We do not have fs_info::fs_state, so that needed to be removed.
- We do not have discard.h sync'ed yet, so that dependency was dropped.
- Anything related to struct super_block was commented out.
- The transaction abort had to be modified to fit with the current
btrfs-progs code.
- Added a btrfs_no_printk() helper to common/messages.* so that the
print statements still worked.
- The 32bit limit checkers are not needed so are behind __KERNEL__
Additionally there were kerncompat.h changes that needed to be made to
handle the dependencies properly. Those are easier to spot.
Any function that needed to be modified has a MODIFIED tag in the
comment section with a list of things that were changed.

Add the GPL v2 header to files where it was missing and is not from an
external source, update to the most recent version with the address.

The implementation of ulist_* is same for kernel and userspace, without
dependencies, so we can keep it separately for code sync.
