Reopening of #320.

The entities session publisher, subscriber and queryables were sharing ownership of the same _z_session_t pointer, this caused issues like #312. This PR replaces the session pointer with a refcounter on the session pointer.

Had to modify how the refcount implementation was handled:

  • Restricted the thread unsafe one to single thread mode only
  • Added a c99 gcc only implementation

And renamed pointer.h / _sptr_t to refcount.h / _rc_t

* fix: build tests only in c11

* fix: remove c11 macros from examples

* feat: add a way to force c99 standard

* ci: add a c99 compilation test

I'd really like that change to the structure of refcounts, but the rest is approved
