The subcanvas is positioned based on the dimensions of the containing
window, so it must be repositioned if the outer window is resized.

This could be a shared variable instead, since it cannot be directly
influenced by gameplay. However, it is influenced by the game mode, and
keeping shared variables that are mode-specific would be more complexity
for very little savings.
- 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.
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.
gcc silently permits this, as does every clang version I tested.
However, in issue #360, thfrwn referenced an e-mail thread that claims
OpenBSD clang warns for this. [1] This capture is not needed, and as
far as I can tell, was not needed even when it was added. It was likely
required in an earlier iteration of the code, but should not have been
pushed. Remove it.

Fixes: d4df692d30 ("Use range_for in draw_all_edges")
Global variable `grd_curcanv` is set to a variety of canvases, some of
which are local stack variables. Use of global variables in this way is
fragile, but works as long as the global is not used beyond the life of
the backing local.
Unfortunately, some existing uses do access the canvas beyond the
lifetime of the backing local. Playing movies sets the font of the
current canvas. If the current canvas is an expired stack variable,
setting the font overwrites other stack data. This data corruption
causes various symptoms, such as inability to play the escape tunnel
movie.
Prior to 03cca2b3dc, the corruption on
playing the endlevel movie had no user-visible effect. That commit
created a large local variable, which changed stack layout. Starting
with that commit, the corruption causes the movie to play as all black.
Fix this, and protect against some other data corruption possiblities,
by clearing the global when the local goes out of scope.

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();:'
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
Changes to common/include/valptridx.h and common/include/fwd-valptridx.h
are manual. All other changes are generated by:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\(v\?\)\(\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/\1m\2/g'
for the 'm' prefix and:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\([cm]\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/i&/g'
