Sparse warns
print-tree.c:1261:49: warning: incorrect type in argument 4 (different base types)
print-tree.c:1261:49: expected unsigned long long [unsigned] [usertype] start
print-tree.c:1261:49: got restricted __le64 [addressable] [usertype] offset
which means we have to use the helper instead of directly accessing the offset
member. This could print bogus number on bigendian arch.

Adds zstd support to the btrfs program. An optional dependency on libzstd
>= 1.0.0 is added. Autoconf accepts `--enable-zstd' or `--disable-zstd' and
defaults to detecting if libzstd is present using `pkg-config'.
The patch is also available in my fork of btrfs-progs [1], which passes
Travis-CI with the new tests. The prebuilt binary is available there.
I haven't updated Android.mk.

While looking at a log of a corrupted fs I needed to verify we were
missing csums for a given range. Make this easier by printing out the
range of bytes a csum item covers.

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.

Print a few more missing items of root_item (there are still some
remaining). Drop key is printend unconditionally.
