1e2a3445d9 radix_tree: debug updates
Some updates to _dump()  debugging function so the printed result
can be more easily examined by human.

Also print 'prefix' as string when all chars are printable.

Add 'simple' variant of _dump also to 'simple' version of radix tree
(which is however normally not compiled).

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.

fd96f1014b gcc: zero-sized array to fexlible array C99
Switch remaining zero sized struct to flexible arrays to be C99
complient.

These simple rules should apply:

- The incomplete array type must be the last element within the structure.
- There cannot be an array of structures that contain a flexible array member.
- Structures that contain a flexible array member cannot be used as a member of another structure.
- The structure must contain at least one named member in addition to the flexible array member.

Although some of the code pieces should be still improved.

0b19387dae headers: use configure.h as 1st. header
Ensure configure.h is always 1st. included header.
Maybe we could eventually introduce gcc -include option, but for now
this better uses dependency tracking.

Also move _REENTRANT and _GNU_SOURCE into configure.h so it
doesn't need to be present in various source files.
This ensures consistent compilation of headers like stdio.h since
it may produce different declaration.

1aac59f82a gcc: avoid shadowing index
Some older headers were declaring 'index' so avoid its usage.

c7789daec0 cov: overflow before widen
Evaluate as 64bit arithmetic (instead of doing 32bit mults which can
in this case purely teoretically overflow).

30b1b57506 cov: add at least ASSERT
Seems lot of code here can't handle failing allocation.
Meanwhile before bigger fix put in asserts in place.

4d964133e2 [radix-tree] alternative radix-tree implementation.
Sacrifices performance for simplicity, meant only for verification of
the real adaptive implementation.
