f439716b75 container_of: use offsetof from stddef
Use standardized offsetof() macro from stddef.
Helps to build valid code with latest gcc10 with -O2.

18aa541ca2 configure: avoid repeative inclusion of configure.h
Since configure.h is a generated header and it's missing traditional
ifdefs preambule - it can be included & parsed multiple times.
Normally compiler is fine when defines have same value and there is
no warning - yet we don't need to parse this several times
and by adding -include  directive we can ensure every file
in the package is rightly compile with configure.h as the
first header file.

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.

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.
