This builds on dbgrbyd.py and dbgbtree.py by allowing for quick
debugging of the littlefs mtree, which is a btree of rbyd pairs with a
few bells and whistles.
This also comes with a number of tweaks to dbgrbyd.py and dbgbtree.py,
mostly changing rbyd addresses to support some more mdir friendly
formats.
The syntax for rbyd addresses is starting to converge into a couple
common patterns, which is nice for quickly determining what type of
address you are looking at at a glance:
- 0x12 => An rbyd at block 0x12
- 0x12.34 => An rbyd at block 0x12 with trunk 0x34
- 0x{12,34} => An rbyd at either block 0x12 or block 0x34 (an mdir)
- 0x{12,34}.56 => An rbyd at either block 0x12 or block 0x34 with trunk 0x56
These scripts have also been updated to support any number of blocks in
an rbyd address, for example 0x{12,34,56,78}. This is a bit of future
proofing. >2 blocks in mdirs may be explored in the future for the
increased redundancy.
