88681f05f1 radix_tree: api change
Instead of using 'key state & key end' uint8_t* switch to use
void* key, & size_t keylen.  This allows easier adaptation with
lvm code base with way too much casting with every use of function.

Also correctly mark const buffers to avoid compiled warnings and
casting.

Adapt the only bcache user ATM for API change.

Adapt unit test to match changed API.

40c1f7889f radix-tree: More debugging of remove
There's now a pretty printer called radix_tree_dump()

n4, n16, and n48 weren't UNSETting the last entry after
sliding values down.

20b9746c5d radix-tree: FIx various bugs to do with removal
Add radix_tree_is_well_formed() which does some sanity checking
of the tree.

Call the above a lot in the unit tests.

Fix revealed bugs.

576dd1fc41 radix-tree: First drop of radix tree.
An implementation of an adaptive radix tree.  Has the following nice
properties:

  - At least as fast as the hash table
  - Uses less memory
  - You don't need to give an expected size when you create
  - It scales nicely (ie. no large reallocations like the hash table).
  - You can iterate the keys in lexicographical order.

Only insert and lookup are implemented so far.  Plus there's a lot
more performance to come.
