Since the current code base is mostly from btrfs-progs, anyone
contributing to U-Boot btrfs code could also help us to improve
btrfs-progs and btrfs kernel module.

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.
