When debuging with "btrfs inspect dump-tree", it's not that handy if we
want to iterate all child tree blocks starting from a specified block.
-b can only print a single block, while without -b "btrfs inspect dump-tree"
will need extra tree roots fulfilled to continue, which is not possible
for a damaged filesystem.
Add a new option --follow to iterate a sub-tree starting from block
specified by --block.

Some tools (check, select-super, dump-super) can use the alternate
superblocks, but the options are not consistent. To make it less
confusing, change the meaning of option -s in 'dump-super' to specify
the superblock copy, instead of taking the offset.
Though this is a change in UI, the old usage is detected and the result
would be the same, no breakage in existing scripts.

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

Previously in 'filesystem resize get_min_size', now
'inspect-internal min-dev-size'. We'd like to avoid cluttering the
'resize' syntax further.
The test has been updated to exercise the new option.

A few minor benefits:
* editors set highliting according to the extensions
* web access to the git repository (github) renders the .asciidoc
files:
* we can link to them from the wiki
* the files are editable via browser and such editations can be
submitted for merge easily
