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

We don't need to conserve stack space too much unlike kernel, also
remove one error condition.

Size of btrfs_path can be reduced by 32 bytes as we don't use the locks
array, down to 112 from 144 bytes.

The structure size went from 56 bytes to 48, which could save some bytes
in larger scale.

4K is quite small, increase it to 64K. This reduces number of
context switches and calls to read. Kernel sends us about 50K of data
per read, so increasing the buffer further does not make any
improvement.
Example run on tests/cli-tests/004-send-parent-multi-subvol:
4K:
- ~800 context switches
- ~5000 calls to read
64K:
- ~450 context switches
- ~500 calls to read

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.

Counting non-zero bytes is wasteful, besides that it would not recognize
uuids containing a 00 value.

Several functions take item but use just the size, we can factor the
item size and use that.

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

The number of distinct key types is not that big that we could waste one
for something new we want to store in the tree.
Similar to the temporary items, we'll introduce a new name for an
existing key value and use the objectid for further extension. The
victim is the BTRFS_DEV_STATS_KEY (248).
The device stats are an example of a permanent item.

name for an existing key value and use the objectid for further
extension. The victim is the BTRFS_BALANCE_ITEM_KEY (248).
The nature of the balance status item is a good example of the temporary
item. It exists from beginning of the balance, keeps the status until it
finishes.
