Change the old btrfsck test infrastructure (btrfs-image dump or xz raw

1) Test case layout
The new infrastructure is dir based, each dir is one test type, and can
contain multiple images/scripts for different corner cases.
So layout will be the following:
btrfs-progs
|-tests
|-fsck-tests
|-001-SOME-CORRUPT-TYPE
|-IMAGE-FOR-CASE1
|-IMAGE-FOR-CASE2
2) Test case image types
Only 2 types for test case images.
a) btrfs-image dump
This one is the simplest case, one only needs to add the image to
corresponding dir.
b) custom script
This one is for all the resting cases which can't fit btrfs-image,
like csum error or script can generate the image (this reduces the
size obviously and good for review)
The old binary dump also belongs to this type, so need to add script
to extract them.

The newly introduced search_chunk_tree_for_fs_info() won't count devid 0

get_device_info() will fill di_args with devid.
This can be trigger by fstests/btrfs/069 and any operations needs to
iterate over all the devices like 'fi show' or 'dev stat' while
replacing.
The fix is do an extra probe specifically for devid 0 after

btrfs-progs: Documentation: fix broken conversion
Fixes various formatting issues:
Fixes quoting issues in various manpages. Before/After excerpts for
mkfs.btrfs(8), btrfs-qgroup(8):
mkfs.btrfs [-A|--alloc-start '<alloc-start>']

id 0/<subvolume id>''
id 0/<subvolume id>
If multiple '<attr>'s is given, use comma to separate.
If multiple <attr>s is given, use comma to separate.
The one that is most apparent is the removal of text in
btrfs-subvolume(8) and others. Before/After:
list [options] [-G <value>] [-C <value>] [--sort=rootid,gen,ogen,path] <path>
list [options] [-G [+|-]<value>] [-C [+|-]<value>] [--sort=rootid,gen,ogen,path] <path>
create [-i <qgroupid>] <name>
create [-i <qgroupid>] [<dest>]<name>
This happens because `<foo>` was replaced by `'<foo>'` in the sed
expression, which is then treated as a constrained quote. As a result,
the `[...]` before the string gets interpreted as "quoted text
attributes".
In this patch, the sed expression is dropped and asciidoc is configured
to recognize `<...>` as a unconstrained quoted string (such that
`<attr>s` is correctly emphasized) and to avoid adding quotes in
contexts where it is not needed.
A remaining problem is that some texts (the one between brackets) do not
add the emphasis for `<...>`. While this could be solved by replacing
`[` and `]` with `[` and `]` using sed, it introduces formatting
problems in btrfs-zero-log(8) because the context is ignored.

btrfs-progs: Fix btrfs fi show by uuid and label
Commit 8be2fff (btrfs-progs: apply realpath for btrfs fi
show when mount point is given) changed the behavior of
btrfs fi show to return an error if the call to realpath()
failed. This broke the ability to specify a filesystem by
uuid or label.
So let's not consider a failed call to realpath() as an
error. If the user really specified a bad device, just
return nothing like we did before.

btrfs-progs: Fix a bug in reset_nlink() which may deletes the recovered file
In reset_nlink(), we believe rec->found_link as accurate number of the
valid links. However it only records the number of found DIR_ITEM, so we
can't use it as reliable value.
Before this patch, in some case, leaf corruption recovery will believe
there is a valid backref but don't add_link() since it can't find any
valid one and don't put it into the lost+found dir.
So the recovered inode will be considered as an orphan item without
orphan item and repair_inode_orphan_item() will add orphan item for it,
causing all the filename/filetype we recovered being a waste of time.

btrfs-progs fix wrong memory free on check_is_root
When "/" is Btrfs, "btrfs property <subcommand> /" regards it
as non-root by mistake.
check_is_root() regards @object as a file system root if
the following two conditions are satisfied.
a) Both @object and its parent directory are Btrfs object
(file system root, subvolume, inode, and device
used for Btrfs).
b) fsid of the above mentioned two objects are different.
It doesn't work if @object is "/" because, in this case,

Btrfs-progs: fsck: add ability to rebuild extent tree with snapshots
This patch makes us to rebuild a really corrupt extent tree with snapshots.
To implement this, we have to verify whether a block is FULL BACKREF.
This idea come from Josef Bacik:
1) We walk down the original tree, every eb we encounter has
btrfs_header_owner(eb) == root->objectid. We add normal references
for this root (BTRFS_TREE_BLOCK_REF_KEY) for this root. World peace
is achieved.
2) We walk down the snapshotted tree. Say we didn't change anything
at all, it was just a clean snapshot and then boom. So the
btrfs_header_owner(root->node) == root->objectid, so normal backref.
We walk down to the next level, where btrfs_header_owner(eb) !=
root->objectid, but the level above did, so we add normal refs for all
of these blocks. We go down the next level, now our
btrfs_header_owner(parent) != root->objectid and
btrfs_header_owner(eb) != root->objectid. This is where we need to
now go back and see if btrfs_header_owner(eb) currently has a ref on
eb. If it does we are done, move on to the next block in this same
level, we don't have to go further down.
3) Harder case, we snapshotted and then changed things in the original
root. Do the same thing as in step 2, but now we get down to
btrfs_header_owner(eb) != root->objectid && btrfs_header_owner(parent)
!= root->objectid. We lookup the references we have for eb and notice
that btrfs_header_owner(eb) no longer refers to eb. So now we must
set FULL_BACKREF on this extent reference and add a
SHARED_BLOCK_REF_KEY for this eb using the parent->start as the
offset. And we need to keep walking down and doing the same thing
until we either hit level 0 or btrfs_header_owner(eb) has a ref on the
block.
