Mac OS X defines uint_fast32_t to unsigned int, causing ambiguous
overloads between RAIIdmem::operator[](std::size_t) and
RAIIdmem::operator[](int). Adding a disambiguating overload for OS X
breaks Windows. Remove operator pointer and operator[]. Rely on the
inherited operator[] for indexing. Require users to call ->get() to
convert to a simple pointer.

Locked doors, including the exit door, were permanently impassable in
Descent 1 because the door has state WALL_DOOR_OPENING even after it has
flags WALL_DOOR_OPENED.

Compiling net_udp.cpp with clang-3.4 crashes the compiler when parsing
a decltype that refers into the class currently being compiled. Parsing
a decltype that refers to a parent class works. Rearrange the decltype
usage to avoid referencing the current class. This makes the code
harder to read and less flexible, but prevents clang from crashing.

[Update: also affects OS X clang v6, as reported by btb: https://github.com/dxx-rebirth/dxx-rebirth/pull/35#issuecomment-73350066]
