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.
- Raise the player limit to 8.
- Remove the logic that forces player counts up/down when switching
between cooperative and deathmatch game modes.
- Add heuristics to add start positions for the extra players, since
standard maps will not have the required number of starts.
This commit enables Rebirth to build with SDL2, but the result is not
perfect.
- SDL2 removed some sticky key support. Rebirth may behave differently
now in this area.
- SDL2 removed some key-repeat related support. Rebirth may behave
differently now in this area.
- SDL2 gained the ability to make a window fullscreen by sizing it to
the desktop instead of by changing the desktop resolution. Rebirth
uses this, and it mostly works.
- Resizing while in the automap does not notify the automap code, so
the view is wrong until the player switches out of automap mode and
back in.
- SDL2 changed how to enumerate available resolutions. Since
fitting the window to the desktop is generally more useful than
fitting the desktop to the window, I chose to drop support for
enumerating resolutions instead of porting to the new API. Users can
now enter an arbitrary window dimension and Rebirth will make an
attempt to use it.
- It might be useful to cap the window dimension at the desktop
dimension, but that is not done yet.
- Entering fullscreen mode through the Controls->Graphics submenu
failed to notify the relevant subsystems, causing the rendered
content not to rescale. For now, compile out the option to toggle
full screen through that menu. Toggling through Alt+Enter works
properly.
Despite these quirks, this is a substantial improvement over the prior
commit, where SDL2 cannot be used at all. The remaining issues can be
resolved in future work.

Currently, DXX_USE_SDL_REDBOOK_AUDIO is an alias for !SDL2. However,
this patch enables interested users to readily patch out Redbook even
for SDL1.

Per comment from kreator, some Apple systems now ship without a working
print screen key. It makes no sense to provide print screen support
bound to a key which does not exist. Add `screenshot=none` and activate
it on OS X to remove the unreachable screenshot support.
digi_play_sample_once is supposed to cancel prior instances of the
sound, but that functionality was lost in
21082c6db2. As a result, the sound can be
stacked up to the limit of the engine. Even when the functionality
existed, its implementation was wrong.
- Change these sounds to be attached to the player generating them.
- Pass the cancellation flag to other players when sending a sound.
- Send the full value of `volume`, rather than truncating it.
- Implement cancellation by killing and restarting the earlier version of a cancelled sound.
- Delete an ugly hack that prevented the patched logic from ever running.
- Fix an ancient quirk in digi_mixer that caused it to report all sounds as not playing, which then caused digi_sync_sounds to instantly cancel the new sound.

Global `Viewer` was copied to local `viewer`, and the local should have
been used in this block. Instead, the global was incorrectly used.

Mako88 reports incorrect images captured when using a screen resolution
of 1366x768. 1366 is not a multiple of 4. Debugging also shows memory
corruption at this resolution, as Mesa writes off the end of the
allocated buffer. Padding the buffer to tolerate these writes is
insufficient, as libpng then crashes with an alignment fault trying to
read unaligned data from the buffer. All these problems are eliminated
by rounding the width and height to the next multiple of 4.

The Windows build did not explicitly include <time.h> or equivalent, but
used `time` and `gmtime`, which are only available when <time.h> is
included. Other platforms include <time.h> incidentally.

clang rejects 0x80000000 as a non-type template argument of type `int`
due to narrowing. Use `INT32_MIN` instead, which has the same numeric
value, and should be accepted without requiring narrowing.

Rather than use an inline wrapper and rely on the compiler optimizer to
redirect gr_set_current_canvas(nullptr) to gr_set_default_canvas,
rewrite all relevant calls directly in the source.
git grep -l 'gr_set_current_canvas' | xargs sed -i -e 's:gr_set_current_canvas(\s*NULL\|nullptr\s*);:gr_set_default_canvas();:'
