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.

In btrfs-dump-tree, we output any existing log tree, however we don't
output the log root tree, which records all root items for log trees.
This makes it confusing for any one who want to know where the log tree
comes from.

When using -t option to output trees not in root tree (chunk/root/log
root), then we output the tree twice.
Fix it

Nodesize is used in kernel, the values are always equal. We have to keep
leafsize in headers, similarly the tree setting functions still take and
set leafsize, but it's effectively a no-op.

For practical purposes teach -t about the human readable names of the
trees in addition to the numerical id. The name syntax is flexible.

The version information could be useful addition to the dump, print it
before we attempt to open the filesystem.

Add new btrfsck option, '--chunk-root', to specify chunk root bytenr.
And allow open_ctree_fs_info() function accept chunk_root_bytenr to
override the bytenr in superblock. This will be mainly used when chunk
tree corruption.

The long-term plan is to merge the features of standalone tools
into the btrfs binary, reducing the number of shipped binaries.
