This version of btrfs_file_read() has the following new features:
- Tries all mirrors
- More handling on unaligned size
- Better compressed extent handling
  The old implementation doesn't handle compressed extent with offset
  properly: we need to read out the whole compressed extent, then
  decompress the whole extent, and only then copy the requested part.

Use extent buffer based infrastructure to re-implement btrfs_readdir().

Along this rework, some small corner cases fixed:
- Subvolume tree mtime
  Mtime of a subvolume tree is recorded in its root item, since there is
  no INODE_ITEM for it.
  This needs extra search from tree root.

- Output the unknown type
  If the DIR_ITEM is corrupted, at least don't try to access the memory
  out of boundary.

This is the extent buffer based path lookup routine.

To implement this, btrfs_lookup_dir_item() is crossported from
btrfs-progs, and implements btrfs_lookup_path() from scratch.

Unlike the existing __btrfs_lookup_path(), since btrfs_read_fs_root()
will check whether a root is a orphan at read time, there is no need to
check root backref, this makes the code a little easier to read.

open_ctree_fs_info() is the main entry point to open btrfs.

This version is a simplfied version of __open_ctree_fd() of btrfs-progs,
the main differences are:
- Parameters on how to specify a block device
  Instead of @fd and @path, U-Boot uses blk_desc and disk_partition_t.

- Remove open_ctree flags
  There won't be multiple open ctree modes in U-Boot.

Otherwise functions structures are all kept the same.

This patch uses generic code from btrfs-progs to read one super block
from block device.

To support the btrfs-progs coding style, the following is also
crossported:
- BTRFS_SETGET_FUNC for btrfs_super_block
- btrfs_check_super() function
- Move btrfs_read_superblock() to disk-io.[ch]
  Since super.c only contains pretty small amount of code, and
  the extra check will be covered in later root read patches.

Differences between this implementation and btrfs-progs:
- No sbflags/sb_bytenr support
  Since we only need to read the primary super block (like kernel),
  sbflags/sb_bytenr used by super block recovery is not needed.

This also changes the following behavior of U-Boot btrfs:
- Only reads the primary super block
  The old implementation reads all 3 super blocks, and also one
  non-existing backup.
  This is not correct, especially if there is another filesystem created
  on the device but old superblocks are not rewritten.

  Just like kernel, we only check the primary super block.
