gcc: avoid shadowing index
...
Some older headers were declaring 'index' so avoid its usage.
/usr/include/string.h:489: warning: shadowed declaration is here

cov: overflow before widen
...
Evaluate as 64bit arithmetic (instead of doing 32bit mults which can
in this case purely teoretically overflow).

cov: add at least ASSERT

Seems lot of code here can't handle failing allocation.
Meanwhile before bigger fix put in asserts in place.

radix-tree: fix bug when erasing elts in remove_prefix
...
_erase_elt() now zeroes the last element of the array (ie. sets to
UNSET). Previously remove() was doing this, but not remove_prefix().

Add radix_tree_is_well_formed() which does some sanity checking
of the tree.
Call the above a lot in the unit tests.

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.
