ziplantil reported that in Descent 1, if a player has an empty Vulcan
cannon, and no energy, then attempting to fire a weapon would play the
SOUND_ALREADY_SELECTED clip every frame until the player ceased trying
to fire. The problem does not impact Descent 2 since Descent 2 does not
play this sound sample when trying to activate a weapon that is already
active.
If the current weapon is already LASER_INDEX, then
select_primary_weapon(LASER_INDEX) simplifies to:
```
// Pointless, player already using this weapon
newdemo_record_player_weapon(LASER_INDEX)
if (Primary_weapon != LASER_INDEX) {
// skipped, path is false
}
else
{
if (wait_for_rearm) // true for this path
// Bad, plays every frame
digi_play_sample(SOUND_ALREADY_SELECTED);
}
// Pointless, Primary_weapon already is LASER_INDEX
Primary_weapon = LASER_INDEX;
if (weapon_name)
{
// skipped, path is false
}
```
Skipping the call avoids two pointless statements, one bad statement,
and nothing useful. Therefore, the simplest fix for the problem is to
call select_primary_weapon(LASER_INDEX) only if the primary weapon is
not currently LASER_INDEX.

Level seismic events and Earthshaker seismic events start with different
intensities, but share everything afterward. Move the common parts to a
function.
When Next_seismic_sound_time is non-zero, a seismic sound is playing.
When Next_seismic_sound_time is zero, no sound is playing. Use this to
eliminate the explicit tracking variable Seismic_sound_playing.
OS X clang warns when a variable is captured but not used. Linux gcc
does not. Remove the unused variable.

All supported compilers have an acceptable <type_traits>. Commit
4cb3d46148 ("Move <type_traits> test to Cxx11RequiredFeature") made
<type_traits> support mandatory in August and no one has objected.
Remove the indirection and use namespace std directly for type_traits
members.
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const
