In fact, the licensing and boost and C++17 changes were already present
in the 2.5.2 version, so I've split this patch in three:
  - drop Boost, require C++17
  - fix licensing
  - bump to 2.5.2

Pleas review the licensing changes, I did quite some substantial
rewrites of the corresponding commit log.

The three resulting patches: applied to master, thanks.

Regards,
Yann E. MORIN.
