The plugins are not mandatory for a successful build, but might result
is no platform plugins being available. The rationale is being able to
build a wayland-only platform.

It currently only supports the platforms that were already supported by
the previous contrib system patching. QT_STATIC is checked from the
qconfig.h file.

Use the existing pkg-config file to detect presence of libgme. This file
is already shipped on all known libgme versions (checked back until
0.6.0, which is from 2015).

This fixes build with recent libgme versions, which added even more
dependencies which were missing in the old check.

Fixes #27262

With libplacebo 4.192.0 being packaged by the contribs, we can increase
our minimum dependency of libplacebo to v4.x. This allows us to drop
backwards compatibility with v3.x, and thus avoid the use of APIs that
wil be removed in libplacebo v5.x.

The header for luac files changed, so the offset to check had to be
increased. Additionally the contrib lua library now has the version in
the filename.

This requires not just new-enough libplacebo, but also libplacebo GL
support. Move the check inside the branch of the latter.

Otherwise, this currently fails compiling on systems with new-enough
libplacebo but no libepoxy.

VLC requires a library version with custom source/destination memory
addresses. Note that we cannot look for symbols as some versions define
them as preprocessor macros aliasing other symbols.

Fixes #27068.

The Linux fbdev subsystem has been deprecated for more than a decade as there are better options available now.

The display module does not actually depend on libdrm in any way.
It can be compiled with just the Linux kernel headers, so do just that.

KMS is a subset of kernel interface. What is tested there is the
presence of libdrm development files.

This is over 11 years old.

C compilers can have GNU extensions to support typeof in C code, but
some C++ compilers like clang are removing the builtin since decltype
can be used in C++ without the constraints from typeof. Decltype is not
100% equivalent for this reason: references will be kept in the returned
type.

The check in m4/typeof.m4 comes from graydon/monotone and dovecot/core
and was slightly modified to namespace the define for C++ code.

x-test syntax (x$foo = xyes/xno) is used to circumvent the fact that
shell variables are substituted and not just defining an argument, so
that $foo doesn't expand to no argument at all.

But "" in posix shell syntax is considered as an argument by itself, so
using quotes around the variable removes this issue. Thus, x-test is
useless in the case where it has been removed in this patch.

This was added ostensibly to fix compilation of the run-time AltiVec
test which was removed in bc146294.
Unfortunately, it causes the compiler to emit AltiVec instructions,
such that the executable crashes if AltiVec is not available.

Regression from e48d6195.

This version gives access to `UpnpInit2` for both IPv6 and IPv4.
`UpnpInit` is deprecated since 1.6 and less safe than `UpnpInit2`.

Libupnp 1.8.3 has been out since 2017 and has been widely adopted in
most linux distributions now (available on debian since version 10).
Dropping support for lower versions will allow us to completely remove
`UpnpInit` from the codebase and simplify a lot the netintf selection
code.

newer clang reports that it ignores the command on each C++ file compiled.
In the end the static C++ compiler is used on Windows anyway.

This avoids potential compiler optimizations when casting to void** when using
IID_PPV_ARGS or WRL.

If the option is not supported we fail the configure as many important C++
modules may not work as expected due to pointer aliasing. In practice this
should never happen as GCC for mingw-w64 and Clang support this correctly.

Maybe it was OK to keep it in 3.0 but in 4.0 we can't expect to reuse ancient
folders, just to save a luac rebuild.

Also add a nice message when configuring.
