Daimona Eaytoy 09d0254172 Better handling of DNONE
This patch includes:
 * Making it possible to access offsets of a DNONE (returning a DNONE)
 * Initializing user-defined variables as DNONE inside short-circuited branches
 * Make DNONE propagate with other operators
 * Make DNONE count as false for logic operators
 * Remove a now-outaded bit in doLevelAtom. In case of shortcircuit,
   $result is now DNONE instead of DNULL, and thus it's possible to
   access offsets of it. Performance++!
 * Don't allow modifying or adding an element of a DNONE as if it were an
    array (to avoid inconsistencies)

This re-applies Id85c673337fa90a3782fd22eb9690cd996967111 with several fixes.

NOTE: Haven't tested locally, although I'm pretty confident thanks to
the amount of tests added.
