If axes!=0 and buttons==0 and hats==0, then the build fails because some
button-related functionality is missing. Move the joystick axis->button
bridge into a conditional to exclude it in this case.

This makes the alignment data structure `chunk` private to interp.cpp,
and allows most files to ignore whether DXX_WORDS_NEED_ALIGNMENT is
enabled, thus improving the ccache hit rate.
lengthof was added to provide the size of C arrays. C++17 std::size is
now available, and can serve the same purpose. Remove the custom
lengthof.
The generated code is the same in both cases, other than the change in
line numbers caused by removal of the #include directives.
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.
A declaration is useful if it declares an external function. A static
inline declaration, if not followed by the definition later in the same
translation unit, will not be useful. Remove such declarations, and
rely on using the definition as a declaration for those files that
actually call partial_range() or similar functions.
This field is used in the SDL build for rendering. In the GL build, its
only purpose is for the editor to write it to a PIG file. Change that
one use to compute the value as needed. Move all other references
behind a preprocessor test for !DXX_USE_OGL. This shrinks the size of
grs_bitmap by 1 pointer, since the compiler added padding after
avg_color up to the size of the next aligned pointer.
gcc has a special case to devolve to memset if both the pointed-at data
and the value to fill are considered a byte. All uses of
DXX_POISON_MEMORY pass a value that fits in a byte, so change the
signature to be a byte, to encourage gcc to activate the special case.
This adds a new dependency, but most systems likely already have
SDL_image installed. Use of SDL_image can be disabled, but this is
discouraged, because various in-game interfaces assume the use of the
original background.
The old implementation automatically corrected for filename case. The
new implementation expects that the supplied filename can be passed to
PYHSFS_openRead as-is. All known uses in-game have been corrected to
satisfy this requirement. If the new stricter match requirement becomes
a problem, a variant of PHYSFSRWOPS_openRead that adjusts filename case
could be created for use here.

Switch valptridx error style dispatching from using macro pasting to
using C++11 user-defined literals. This makes the code a bit easier to
read, and removes the need for a C99-conforming preprocessor here, which
should help anyone trying to port to Microsoft Visual Studio.
The new implementation also fixes a limitation of the previous
implementation. Before, an override that referenced an invalid name
could be silently ignored. Now, incorrect overrides cause an attempt to
use an undefined instantiation, which fails with a compilation error.
The minimum supported compiler versions now provide a depth-efficient
implementation of std::make_index_sequence, which removes the last
reason to carry a private implementation. In the case of clang, it
appears to have a special compiler intrinsic used to implement its
std::make_index_sequence.
Switch to the compiler-provided version for both gcc and clang.
Commit d355ef4030 removed a seemingly unnecessary modification of the
global variable grd_curcanv->cv_font, after eliminating all local reads
of it. However, a non-local read, buried in listbox_mouse, depended on
grd_curcanv->cv_font being set to a MEDIUM font. After that commit,
grd_curcanv->cv_font retained its prior value, which is not a MEDIUM
font. This caused listbox_mouse to compute an incorrect height of the
lines in the listbox, which manifested as the game choosing the wrong
line when the mouse is clicked in the listbox.
Fix the problem by explicitly using MEDIUM3_FONT, since that was
usually the value left in grd_curcanv->cv_font prior to that commit. In
some cases, a different MEDIUM font would be left there, but all the
MEDIUM fonts have the same height, so they are interchangeable for this
purpose.

gcc before gcc-7 failed to build valptridx:
```
common/include/valptridx.h: In instantiation of 'valptridx<managed_type>::ptridx<policy>::ptridx(const valptridx<managed_type>::ptridx<rpolicy>&) [with rpolicy =
valptridx<dcx::segment>::vm; typename std::enable_if<(policy:: allow_nullptr || (! rpolicy:: allow_nullptr)), int>::type <anonymous> = 0; policy = valptridx<dcx::segment>::vc; managed_type = dcx::segment]':

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
common/include/valptridx.h:666:31: note: declared protected here
using vptr_type = ptr<policy>;
```
This cannot be fixed in the obvious way because the error message is
wrong:
```
664 using containing_type = valptridx<managed_type>;
665 public:
666 using vptr_type = ptr<policy>;
667 using vidx_type = idx<policy>;
668 using typename vidx_type::array_managed_type;
```
The type declarations _already are_ *public*, not *protected* as the
message states. Relaxing the protection on the containing class
resolves the error. This looks bad from an encapsulation perspective,
but does not make the code incorrect.
arch_close calls various library shutdown routines, some of which may
not be in good order after atexit hooks begin executing. Call it before
returning from main, so that the libraries are still fully initialized.
gcc considers strong_typedef to be POD both with and without the
explicit default. clang considers it to be POD only if the constructor
is explicitly defaulted.
For correctness, valptridx::ptridx instances must not be sliced down to
their component ::ptr or ::idx base classes. Previously, this was done
with a dummy template parameter to ensure that a bare ::idx had a
different type than the idx base of a ::ptridx. This extra distinction
complicates analysis of the code, and is not needed when the code is
already correct. Add the ability to build without slice checking.
Fix a bug where the ptridx converting move constructor delegated to the
ptr converting copy constructor, since the ptr copy constructor had
filename/line arguments, the ptr move constructor did not, and the
ptridx move constructor always passed filename/line.

Add a `using` statement to switch `report_error_uses_exception` to
`public` access. Nothing else uses it, and there is no design purpose
served by keeping it `protected`.
Each axis can act as two buttons in both ways.
For example, a player might map slide left and slide right to J1 -A1 and J1 +A1 as button presses instead of the slide L/R axis.
This is mostly to fix XBox 360 Controller Left and Right triggers. But it can work on every axis if the player wishes to bind them.
