There is another variable shadowing problem which can only be exposed
if experimental features are enabled.
Inside the branch of BTRFS_PRINT_TREE_CSUM_HEADERS, we declare another
local variable @csum, shadowing the @csum of print_header_info(), which
is only declared when experimental features are enabled.
Just rename the @csum to @tree_csum to avoid the problem.

The variable @e is only utilized to record the errno from ioctl() call,
and is only for the error message.
We can go with "%m" to replace the usage of variable @e, and remove the
variable shadowing, as later we will declare a local variable @e with a
different type.

The accelerated crc32c needs to check for two CPU features, the crc32c
instructions is in SSE 4.2 and 'pclmulqdq' is a separate. There's still
old hardware used that does not have the PCLMUL instructions. Detect it
and make it the condition.
The pclmul is not supported on old compilers so also add a
configure-time detection and leave the SSE 4.2 only implementation as
the accelerated one if possible.

For a skinny metadata item in the extent tree, the key offset represents
the level of the tree it points to. This adds a check that these values
match, as otherwise it can cause a volume to go readonly when deleting a
large number of inodes.

[PROBLEM]
Btrfstune allows multiple different options to be executed in one go,
some options are completely fine, like no-holes along with extref, but
with more and more options, we need more exclusive checks.
In fact a lot of new options are already not following the old
success/total checks.
[ENHANCEMENT]
There is really no need to allow multiple features to be set in one go.
So this patch introduces an array which groups all the compatible
options into following categories:
- Extent tree
This includes converting to/from extent and block group tree.
- Space cache
This includes converting to v2 space cache.
- Metadata UUID
This includes changing metadata uuid.
- FSID change
This includes the slower full fs fsid rewrites.
- Csum change
This includes the csum rewrites.
- Seed devices
This includes changing the device seed flag.
- Legacy options
This includes no-holes/extref/skinny-metadata features, which are
already default mkfs features.
Now we only allow options inside the same group to be specified.
E.g. "btrfstune -r -S 1" would fail as it includes both legacy and seed
groups.
Meanwhile "btrfstune -r -n" would still be allowed.

In the function set_metadata_uuid(), we set the flag
BTRFS_SUPER_FLAG_CHANGING_FSID_V2 in step 1 at line 71 as shown below:
71 super_flags |= BTRFS_SUPER_FLAG_CHANGING_FSID_V2;
72 btrfs_set_super_flags(disk_super, super_flags);
73 ret = btrfs_commit_transaction(trans, root);
However, we fail to reset this flag if there is no change in the fsid on
the incoming disks, as we return too early.
105 } else {
106 /* Setting the same fsid as current, do nothing */
107 return 0;
Fix this by allowing the thread to pass through the step 2, where we
reset the flag.
