Reloc tree is a special tree with very short life span. It acts as a
special snapshot for any tree, with related nodes/leaves or EXTENT_DATA
modified to point to new position.
Considering the short life span and its special purpose, it should be
quite reasonable to keep them as both corner case for fsck and
educational dump for anyone interested in relocation.

For snapshot shared tree blocks with source subvolume, the keyed backref
counter only counts the exclusive owned references.
In the following case, 258 is a snapshot of 257, which inherits all the
reference to this data extent.
------
item 4 key (12582912 EXTENT_ITEM 524288) itemoff 3741 itemsize 140
refs 179 gen 9 flags DATA
extent data backref root 257 objectid 258 offset 0 count 49
extent data backref root 257 objectid 257 offset 0 count 1
extent data backref root 256 objectid 258 offset 0 count 128
extent data backref root 256 objectid 257 offset 0 count 1
------
However lowmem mode used to iterate the whole inode to find all
references, and doesn't care if a reference is already counted by the
shared tree block.
Add the test case to check it.

The image is dumped by modifying kernel to sleep long enough before
merging relocation trees, so we can just copy the whole image to other
place before kernel begins to merge reloc trees.
And the base image is created by the following script to bump metadata
size:
------
dev=~/test.img
mnt=/mnt/btrfs
umount $mnt &> /dev/null
fallocate -l 128M $dev
mkfs.btrfs -f -n 4k -m single -d single $dev
mount $dev $mnt -o nospace_cache,max_inline=2048
btrfs subvolume create $mnt/src
for i in $(seq -w 0 128); do
xfs_io -f -c "pwrite 0 2k" $mnt/src/file_$i > /dev/null
done
for i in $(seq -w 0 64); do
btrfs subvolume snapshot $mnt/src/ $mnt/snapshot_$i
touch $mnt/snapshot_$i/new
done
sync
------
The image triggers several corner cases that the old lowmem mode didn't
consider.
Like metadata backref with FULL_BACKREF flag and only SHARED_BLOCK_REF
backrefs for metadata. And several tree reloc trees with shared
leaves/nodes to confuse old lowmem mode.

The image has 2 problems mixed:
1) Too small super total_bytes
This super total_bytes is manually modified to create such problem.
2) Unaligned dev item total_bytes
This is created by v4.12 kernel, with 128M + 2K device added, and
original device removed.
Then we can create such image with unaligned dev item total_bytes.

Since lowmem mode can repair certain corruptions (mostly in fs tree),
insert a beacon into each fsck test cases to allow some of them be
tested in lowmem mode.
With this patch, fsck option override will check the beacon file
".lowmem_repairable" in the same directory of the test image, and if the
beacon exists, then it will also run lowmem mode repair to repair the
image.

Lowmem mode only repairs few cases which has a beacon file
".lowmem_repairable" in the case' directory.
However, defining TEST_ENABLE_OVERRIDE=true in command line does work
in above strategy.
Because _skip_spec() in tests/common.local isn't interpreted by shell
in that case.
Solve it by making _skip_spec() always be defined in common.local.

kernel 4.14 introduces new function for checking if all chunks is ok for
mount with -o degraded option.
commit 21634a19f646 ("btrfs: Introduce a function to check if all
chunks a OK for degraded rw mount")
As a result, raid0 profile cannot be mounted with -o degraded on 4.14.
This causes failure of the misc-test 011 "delete missing device".
Fix this by using raid1 profile for both data and metadata.
This also should work for kernel before 4.13.
