- add dup2 functionality. This requires adding a ref cnt to the
_WS_connections structure so that we only free the structure once
all dup'd referenced are closed. Also, refactor malloc and free of
connection structure into _WS_alloc and _WS_free.
- allow select to accept a NULL timeout value which means sleep
forever instead of segfaulting.
- fix some compile warnings related to ppoll definition.
- move some WebSockets related html test pages into utils and symlink
them from tests.
