open_file_or_dir3() with O_RDONLY passed in the flags, as this avoids

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.

When 'btrfs device scan' command is invoked, it scans all devices,
check them for btrfs superblock and add devices with btrfs to a list.

Next, each device from the list is passed to kernel where it is handled
in the btrfs_scan_one_device() function. This function can, for example,
return -EBUSY when device contains superblock matched to existing and
mounted filesystem (if this device was pulled out from RAID and
connected again after some time).

btrfs tool stops device scan if any device has been failed to add, so
other existing devices with (possibly) valid FS will never be reached.

Fix this by remove stopping at any failure in the btrfs_register_all_devices(),
just return error count. btrfs_scan_one_device() reports any kind of
error already.

This isn't as simple as adding up shared extents - they may be shared with
each other, and may also overlap. This patch uses an interval tree to store
shared extents we find while fiemapping files. After collecting them, a 'set
shared' count is calculated by summing (without overlap) each shared region
discovered. This is then displayed to the user as 'set shared'.

'btrfs du' differs from regular du in that it will work to resolve which
blocks are shared between files in its list. This gives the user a more
accurate bytecount from which they can make decisions regarding management
of their file space.

We still print a total number of bytes counted (like regular du), but also
print the number of bytes which were found to have been shared amongst the
file set provided. From there it becomes trivial to calculate how much space
is exclusively owned.
