Cache the super-block's checksum type field in 'struct recover_control'.
This will be needed for further refactoring the checksum handling.

The only difference between parse_limit and parse_size is that
parse_limit accepts "none" as a valid input. That's easy enough to
handle as a special case and lets us drop the duplicate code.

We want just one header for the check API (similar to what mkfs does)
but as btrfsck.h is exported header (libbtrfs), it needs some
deprecation beriod before it's moved through there are probably no users
of that header file in particular.
Copy the header to check, all modifications and cleanups won't affect
the public header.

Move the full-balance warning to before the fork, so that the user can
see and react to it.
Notes on test:
- Don't use grep -q, as it causes a SIGPIPE during the countdown, and
the balance thus doesn't start.
- The "balance cancel" is superfluous as the last command, but it
provides some idempotence and allows adding more tests below it.

User reports:
"When I execute btrfs restore -S to restore a symlink, it prints:
SYMLINK: 'dest/path/of/symlink' => 'symlink/target'
Failed to change owner: Bad file descriptor
And at cmds-restore.c#L937:
ret = fchownat(-1, file, btrfs_inode_uid(path.nodes[0], inode_item),
btrfs_inode_gid(path.nodes[0], inode_item),
AT_SYMLINK_NOFOLLOW);
"
The -1 is indeed a bad descriptor, and should be probably AT_FDCWD as
this is documented. The path passed as 'file' is always absolute, so the
semantics are unaffected.

In process_clone(), we're not checking the return value of strdup().
But, there's no reason to strdup() in the first place: we just pass the
path into path_cat_out(). Get rid of the strdup().

The comman 'btrfs inspect dump-tree <dev>' will scan all the devices
from the filesystem by defaul.
So as of now you can not inspect each mirrored device independently.
This patch adds option --noscan, which when used won't scan the system
for the partner devices, instead it just uses the devices provided in
the argument.
For example:
btrfs inspect dump-tree --noscan <dev> [<dev>..]
This helps to debug degraded raid1 and raid10.

fgets consumes n-1 bytes from input buffer.
When a user types y\n, the newline is left in the buffer. As a result,
the next fgets uses that \n as answer without waiting for the user to
type.
This patch also fix a bug that dereference the ret without checking if
it's NULL.
* Consumes the `\n` from stdin buffer
* Avoid NULL pointer dereference: treat EOF as default value

When a scrub completes or is cancelled, statistics are updated for
reporting in a later btrfs scrub status command and for resuming the
scrub. Most statistics (such as bytes scrubbed) are additive so scrub
adds the statistics from the current run to the saved statistics.
However, the last_physical statistic is not additive. The value from the
current run should replace the saved value. The current code incorrectly
adds the last_physical from the current run to the previous saved value.
This bug causes the resume point to be incorrectly recorded, so large
areas of the disk are skipped when the scrub resumes. As an example,
assume a disk had 1000000 bytes and scrub was cancelled and resumed each
time 10% (100000 bytes) had been scrubbed.
Run | Start byte | bytes scrubbed | kernel last_physical | saved last_physical
1 | 0 | 100000 | 100000 | 100000
2 | 100000 | 100000 | 200000 | 300000
3 | 300000 | 100000 | 400000 | 700000
4 | 700000 | 100000 | 800000 | 1500000
5 | 1500000 | 0 | immediately completes| completed
In this example, only 40% of the disk is actually scrubbed.
This patch changes the saved/displayed last_physical to track the last
reported value from the kernel.

This adds a global --format option to request extended output formats
from each command.
We currently only support text mode. Command help reports what
output formats are available for each command. Global help reports
what valid formats are.
If an invalid format is requested, an error is reported and lists the
valid formats.
Each command sets a bitmask that describes which formats it is capable
of outputting. If a globally valid format is requested of a command
that doesn't support it, an error is reported and command usage dumped.
Commands don't need to specify that they support text output. All
commands are required to output text.
