Christopher Haster 9b803f9625 Reimplemented tree rendering in dbg*.py scripts

The goal here was to add the option to show the combined rbyd trees in
dbgbtree.py/dbgmtree.py.

This was quite tricky, (and not really helped by the hackiness of these
scripts), but was made a bit easier by adding a general purpose tree renderer
that can render a precomputed set of branches into the tag output.

For example, a 2-deep rendering of a simple btree with a block size of
1KiB, where you can see a bit of the emergent data-structure:

  $ ./scripts/dbgbtree.py disk -B1024 0x223 -t -Z2 -i
  btree 0x223.90, rev 46, weight 1024
  rbyd                       ids       tag                     ...
  0223.0090:     .-+             0-199 btree w200 9            ...

This tree renderer also replaces the adhoc tree rendere in dbgrbyd.py
for consistency.
