btrfs-progs: restore, fix page alignment issue for lzo compression
When runing restore under lzo compression, "bad compress length"
problems are encountered.
It is because there is a page alignment problem with the @decompress_lzo,
as follows:
|------| |----|-| |------|...|------|
page ^ page page
|
3 bytes left
When lzo pages are compressed in memory, we will ensure that the 4 bytes
length header will not cross a page boundary. There is a situation that
3 (or less) bytes are left at the end of a page, and then the 4 bytes
len is stored at the start of the next page. But the @decompress_lzo
doesn't go to the start of the next page and continue to read the next 4
bytes which crosses two pages, so a random value is fetched as a "bad
compress length".
So we check page alignment every time before we are going to fetch the
next @len and after the former piece of data is decompressed. If the
current page that we reach has less than 4 bytes left, then we should
fetch the next @len at the start of next page.

And this makes test result quite annoying since it fails to mount and
still continue, which will always fail.
This patch will check 'sudo -v -n' and 'sudo -n true' to determine
whether sudo works fine in different version/settings, since in some
setting/version, 'sudo -v -n' will fail even the user is set NOPASSWD.
Also, remove the 'have_root_helper' variant, since there is a
possibility that sudo credential will timeout during the test and
'have_root_helper' won't help to detect such problem.

The next inode to be fixed is the following:

Since the move failed, the LINK_COUNT_ERR flag is not cleared, the inode

Btrfs-progs: fix bad extent flag
We can have FULL_BACKREF set or not set when we need the opposite, this patch
fixes this problem by setting a bit when the flag is set improperly. This way
we can either correct the problem when we re-create the extent item if the
backrefs are also wrong, or we can just set the flag properly in the extent
item. Thanks,

Btrfs-progs: skip opening all devices with restore
When we go to fixup the dev items after a restore we scan all existing devices.
If you happen to be a btrfs developer you could possibly open up some random
device that you didn't just restore onto, which gives you weird errors and makes
you super cranky and waste a day trying to figure out what is failing. This
will make it so that we use the fd we've already opened for opening our ctree.

btrfs-progs: fix btrfs-image overlapping chunks
If you create a metadump from a striped volume you will have chunks that refer
to different logical offsets with the same physical offset on different devices.
So when we do the restore we just truncate the number of stripes in each chunk
item and carry on, which causes problems because we then have chunks that point
to the same physical offset for different logical offsets. To handle this
problem we keep track of logical extents that overlap on physical extents.
Then we go back and remap these extents into different physical extents on the
disk we are restoring onto. This makes us actually able to restore a multi disk
