Only respawn when the player presses a fire key/button (primary,
secondary, or flare). Only clear primary, second, flare, and bomb when
respawning. This allows dead players to use the automap or change their
camera views.
This is a necessary step to flushing only the firing inputs on respawn,
as requested by Mako88 in
<https://github.com/dxx-rebirth/dxx-rebirth/issues/104>. Currently,
inputs are flushed again by the activation of the game window, so
respawn still flushes all inputs.

In every case but one, create_shortpos was called with a constant flag
equal to words_bigendian. The demo system called it with a constant 0.
Split create_shortpos into create_shortpos_little and
create_shortpos_native. Use create_shortpos_native for the demo system,
and create_shortpos_little everywhere else.
gcc-4.6 chokes on `static constexpr type value{};`, but accepts
`static constexpr auto value = type{};`
