94fced6353 btrfs-progs: build: drop kernel-lib from -I and update paths
Include the files by full path to avoid any confusion in case of
potentially duplicate names.

f63f29e9e9 btrfs-progs: move internal.h to common/
Create directory for all sources that can be used by anything that's not
rellated to a relevant kernel part, all common functions, helpers,
utilities that do not fit any other specific category.

The traditional location would be probably lib/ with all things that are
statically linked to the main binaries, but we have libbtrfs and
libbtrfsutil so this would be confusing.

680f4c8752 btrfs-progs: Export btrfs_create_tree() and move it to disk-io.c
Just as how kernel uses it.

This provides the basis for later uuid creation.

set_free_space_tree_thresholds() is never used, just remove it to solve

c4aadd9af2 btrfs-progs: Add support for metadata_uuid field
Add support for a new metadata_uuid field. This is just a preparatory
commit which switches all users of the fsid field for metdata comparison
purposes to utilize the new field. This more or less mirrors the
kernel patch, additionally:

 * Update 'btrfs inspect-internal dump-super' to account for the new
 field. This involes introducing the 'metadata_uuid' line to the
 output and updating the logic for comparing the fs uuid to the
 dev_item uuid.

01e35d9f53 btrfs-progs: treewide: Fix missing declarations
Found using -Wmissing-prototypes in GCC.  This should improve LTO
behavior.

Note that set_free_space_tree_thresholds is an unused function. Adding
inline seems to remove the unused function warning.

8c028efe4a btrfs-progs: Pull free space tree related code from kernel
To help implement free space tree checker in user space some kernel
function are necessary, namely iterating/deleting/adding freespace
items, some internal search functions. Functions to populate a block
group based on the extent tree. The code is largely copy/paste from
the kernel with locking eliminated (i.e free_space_lock). It supports
reading/writing of both bitmap and extent based FST trees.

e444c7bfa6 btrfs-progs: check: Fix wrong error message in case of corrupted extent
When btrfs check detects a freespace tree extent which ends beyond the
blockgroup containing it a misleading error messages is printed. For
example if we have the following extent in the freespace tree:

    item 5 key (30408704 FREE_SPACE_INFO 1073741824) itemoff 16259 itemsize 8
            free space info extent count 3 flags 0
    item 6 key (30425088 FREE_SPACE_EXTENT 49152) itemoff 16259 itemsize 0
            free space extent
    item 7 key (30507008 FREE_SPACE_EXTENT 65536) itemoff 16259 itemsize 0
            free space extent
    item 8 key (30654464 FREE_SPACE_EXTENT 14524648038063310901) itemoff 16259 itemsize 0

Clearly the last extent is corrupted so we should print something
along the lines of:

free space extent ends at 14524648038063310901, beyond end of block group 30408704-1104150528

Instead currently this is printed:

free space extent ends at 30654464, beyond end of block group 30408704-1104150528

So instead of printing the actual erroneous end, we print the beginning
of the extent. Fix this by printing the actual corrupted end.

This function actually uses only the extent_buffer arg but takes 3
arguments. Furthermore, it's current interface doesn't even mirror
the kernel counterpart. Just remove the extra arguments.

e4797df6a9 btrfs-progs: check the free space tree in btrfsck
This reuses the existing code for checking the free space cache, we just
need to load the free space tree. While we do that, we check a couple of
invariants on the free space tree itself. This requires pulling in some
code from the kernel to exclude the super stripes.
