In some cases it's clear from the context which item is being printed,
so we can remove them. If the item has no data, some description is
still desired (eg. orphan or various backrefs).

There are likely more places where the wrong size types are used, but
these tripped Clang's warnings because they eventually get passed to
printf.

The only reasom read_tree_block() needs a btrfs_root parameter is to get
its node/sector size.
And long ago, I have already introduced a compactible interface,
read_tree_block_fs_info() to pass btrfs_fs_info instead of btrfs_root.
Since we have cleaned up all root->sector/node/stripesize users, we
should be OK to refactor read_tree_block() function.

Btrfs header has a u64 member flags, whose lowest 56 bits are for header
flags like WRITTEN and RELOC.
And its highest 8 bits are for backref revision.
Manually checking btrfs_header_flags() will be a pain, so add such leaf
flags and backref revision output for print-tree.

The DEV_STATS and BALANCE_ITEM have been deprecated in favor of more
general items, print the new names in the dump.

There's lots of code that passes btrfs_item_ptr. Add a helper to extract
the ptr at the beginning, ignoring the type. The print functions take
the correct type, but we ignore it in the conversion macros as it does
not provide the type checking anyway.
If the typed variable is used more than once, it's kept in place.

Rename to the structure members, add underscore so it's a single word.
Compression is also printed as raw value.

Before this patch, only 3 inode flags have readable string: NODATACOW,
NODATASUM, READONLY.
This patch will output all readable strings for remaining inode flags,
making debug-tree tool more handy.

This function is quite useful for a lot of error report.
Enhance it to support custom output other than stdout.
And export it for later btrfsck enhancement.

Now that we can verify all qgroups, we can write the corrected qgroups out
to disk when '--repair' is specified. The qgroup status item is also updated
to clear any out-of-date state. The repair_ functions were modeled after the
inode repair code in cmds-check.c.
I also renamed the 'scan' member of qgroup_status_item to 'rescan' in order
to keep consistency with the kernel.
Testing this was easy, I just reproduced qgroup inconsistencies via the
usual routes and had btrfsck fix them.

To start, let's tell btrfs-progs to read the free space root and how to
print the on-disk format of the free space tree. However, we're not
adding the FREE_SPACE_TREE read-only compat bit to the set of supported
bits because progs doesn't know how to keep the free space tree
consistent.
