btrfs-progs: show-super: copy implementation of btrfs_read_sys_array
btrfs-show-super has own implementation to read the sys array and it
lacks all the sanity checks.
Copy and adapt the improved implementation from btrfs_read_sys_array.
This will fix crashes on a fuzzed/corrupted images. It's duplicating
code but at the moment looks easier than refactoring and restructuring
btrfs_read_sys_array that now almost matches the kernel code, which we
want in the long term.

btrfs-progs: mkfs: allow --data DUP for single device
Current code don't support DUP profile on single device, except it
is in mixed mode, because of following reasons:
1: Some SSD do deduplication internally, so the duplication on
the filesystem side has no effect.
2: On a physical device, if the entire disk broken, --data DUP does not
help.
3: Half performance compared to single profile.
4: We have a workaround: create multi-partition on a single device,
and btffs will treat them as multi device.
Instead of refusing --data DUP, we give the user a choice and print
a wrning.
Test:
1: Tested by xfstests
Run with modified xfstests, I add test items of -d dup in single
device into btrfs/* and common/rc, run tests of btrfs/*,
with all mount option, no regression diffed with v4.3.

btrfs-progs: Fix partitioned loop devices resolving
When using partitions on a loop device, the device's name can be
e.g. /dev/loop0p1 or similar, and no relevant entry exists in the /sys
filesystem, so the current resolve_loop_device function fails.
Instead of using string functions to extract the device name and reading
this file, this patch uses the loop device API through ioctl to get the
correct backing file.

btrfs-progs: mkfs: increase buffer size in is_ssd
In current versions of util-linux the buffer passed to blkid_devno_to_wholedisk
has to be sufficiently large to not only hold the device name but the complete
target of the /sys/dev/block/<maj:min> symlink. This was changed only recently
in
4419ffb9eff5801fdbd385a4a6199b3877f802ad.
The small buffer size currently can lead to failure of is_ssd due to truncated
device names:
readlink("/sys/dev/block/254:7", "../../devices/virtual/block/dm-", 31) = 31
open("/sys/block/dm-/queue/rotational", O_RDONLY) = -1 ENOENT (No such file or directory)
