For ext* fs containing a large hole(larger than 128M), btrfs-convert
will only insert one 128M hole extent and skip the remaining.
This leads to discontinuous file extents.
Add test case for it, and since it's a pinpoint regression test case, no
combination of convert options nor checksum verification.

The usage of 'source' is a bashism, and '.' should be used instead. This
is causing fuzz-tests/001-simple-unmounted to fail in systems where
/bin/sh isn't bash:
[TEST/fuzz] 001-simple-unmounted
./test.sh: 5: ./test.sh: source: not found
./test.sh: 7: ./test.sh: setup_root_helper: not found
./test.sh: 8: ./test.sh: check_prereq: not found
./test.sh: 18: ./test.sh: check_all_images: not found
Since most (all?) tests actually use /bin/bash, change this test to use
bash too.

New convert introduced simpler chunk/extent allocation algorithm, at the
cost of complex backup superblock migration codes.
Use specially built ext2 images to test if btrfs-convert can convert and
rollback images without problem.
All these special ext2 image have blocks/holes across 2nd btrfs backup
superblock.
The naming of test image is like the following:
|<------superblock migration range----->|
64M 64M + 64K
|-Data--|-Data--|/Hole//|-Data--|/Hole//|-Data--|--Data--| = drdhdhdrd
These test cases should check all typical layouts and make sure new
convert works.

Add support for custom convert test scripts, just like fsck tests.
Instead of generic convert tests, we need more specifically created images
for new convert tests.
This patch provide the needed infrastructure for later convert test
cases.

New convert framework uses new and simpler chunk layout, while the cost
is the more complex superblock range migration logical, compared to old
convert.
Enhance the convert test script to create file which will takes up 2nd
backup superblock space, to ensure the superblock migration is working
as expected.

In order to confirm that btrfsck supports to check a variety of
refs, add the
following cases:
* keyed_block_ref
* keyed_data_ref
* shared_block_ref
* shared_data_ref
* no_inline_ref (a extent item without inline ref)
* no_skinny_ref
