Instead of creating the powerup from a player, then overwriting the
location and velocity of the powerup, and fixing up its segment, create
the powerup directly where it should be, with the intended velocity.
Iterating over it returns each side number in turn. This allows
converting many loops of the form:
```
for (int i = 0; i < MAX_SIDES_PER_SEGMENT; ++i)
```
to the compact form:
```
for (const auto i : MAX_SIDES_PER_SEGMENT)
```
The compact form brings the usual benefit of range-based for: delegating
iteration to the compiler prevents the loop body from skipping a step,
and makes clear in the code that this is the case.
Callers only ever test for whether the movie was skipped, and never
distinguish between a movie that ran to completion versus a movie that
the user interrupted. Combine these two statuses into one value, and
eliminate the logic in RunMovie that picked which of the two to return.
The index and the value were transposed, and since both were integer
types, the type system was unable to warn that the new code was
incorrect. Swap the variables to bind as intended.

Fixes: de4efc4f46 ("Qualify more uses of shared_segment members")
gcc and clang disagree about how to disambiguate when an identifier is
both a typename and a member. Avoid the disagreement by renaming the
member.

This was once a compatibility shim, but compiler support for std::begin
has been required since 5e434cbe95 and no
issues have been reported. Flatten the include tree by removing this
header and using the STL names directly.
endlevel wants to freeze the console player's last in-mine position.
Instead of copying the position out and back, refactor the flow to let
endlevel skip the update of the position.
Only the console player's last position needs to be remembered across
frames. Copy the console player's position out before processsing
object movement. For all other objects, retain a temporary for use by
the position recovery code.
exit_segnum is set during load_endlevel_data, which currently runs too
early for this to depend on the exit used, and thus to be player-unique.
That data should be loaded at need, when the level ends, rather than
during level setup. This can be addressed later, when support for
multiple exits is improved.
transition_segnum is a function of how the player exited the mine, since
there could be multiple exit tunnels, although current code appears not
to handle that well in other places. Therefore, it needs to be
per-player data, not part of the level data, where it would not depend
on the player exiting.
