Many subcommands have their own verbosity options that are being
superseded by the global options. Update the help text to reflect that
where applicable.

Some scripts can still rely on this message, so make it available with
-vv, so -v stays sane.

The old code of copy_one_extent() is a mess:
- The main loop is implemented using goto
- @mirror_num is reset to 1 for each loop
- @mirror num check against @num_copies is wrong for decompression error
This patch will fix this mess by:
- Use read_extent_data()
read_extent_data() has all the good wrapping of btrfs_map_block()
and length check.
This removes a lot of complexity.
- Add extra file extent offset check
To prevent underflow for memory allocation
- Do proper mirror_num check for decompression error

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.

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
