btrfs-progs: utils: make sure set_label_mounted uses correct length buffers
When `btrfs filesystem label /foo bar` command is invoked, it will pass
the buffer allocated in the argv array directly to set_label_mounted()
and then to the BTRFS_IOC_SET_FSLABEL ioctl.
However, the kernel code handling the ioctl will always try to copy
BTRFS_LABEL_SIZE bytes[1] from the userland pointer. Under certain
conditions and when the label is small enough, the command will fail
with:
[root@localhost /]# btrfs filesystem label /mnt f
ERROR: unable to set label Bad address
Fix this by making sure we pass a BTRFS_LABEL_SIZE sized buffer to the
ioctl containing the desired label.

btrfs-progs: fix fi du so it works in more cases
Currently, btrfs fi du uses open_file_or_dir(), which tries to open
it's argument with O_RDWR. Because of POSIX semantics, this fails for
non-root users when the file is read-only or is an executable that
is being run currently, or for all users (including root) when the
filesystem is read-only. This results in a somewhat confusing 'Unknown
error -1' message when trying to check such files. Switch to using
open_file_or_dir3() with O_RDONLY passed in the flags, as this avoids
the limitations listed above, and we have no need to write to the files
anyway (and thus shouldn't be opening them writable).

btrfs-progs: add stat check in open_ctree_fs_info
Currently, open_ctree_fs_info will open whatever path you pass it and try
to interpret it as a BTRFS filesystem. While this is not nessecarily
dangerous (except possibly if done on a character device), it does
result in some rather cryptic and non-sensical error messages when
trying to run certain commands in ways they weren't intended to be run.
Add a check using stat(2) to verify that the path we've been passed is
in fact a regular file or a block device, or a symlink pointing to a
regular file or block device.
This causes the following commands to provide a helpful error message
when run on a FIFO, directory, character device, or socket:
* btrfs check
* btrfs restore
* btrfs-image
* btrfs-find-root
* btrfs inspect-internal dump-tree
stat(2) is used instead of lstat(2), as stat(2) follows symlinks just
like open(2) does, which means we check the same inode that open(2)
opens, and thus don't need special handling for symlinks.
