The C++ standard says it must, but some badly-configured toolchains seem
to be lacking support.
In particular, for some 32-bit platforms without native support for
them, GCC implements 64-bit atomics via out-of-line functions in
libatomic. If that library is missing... well, then std::atomic 64-bit
doesn't work and we mustn't try to use it.

You can choose between system, qt, and no libdouble-conversion
support. If you choose "no", snprintf_l and sscanf_l will be
used.
By default, system double conversion is used if the system provides a
double-conversion library. Otherwise the bundled libdouble-conversion
is built. sscanf_l and snprintf_l are not used by default as the
planned "shortest" conversion mode to produce the shortest possible
string will give less precise results when implemented with snprintf_l.

This commit removes the legacy ptrsize check, which was deficient
because it did not work for multiarch systems (when we supported fat
OS X binaries) and did not work for bootstrap builds because the size
might be different when cross-compiling.
Instead, let's rely on the predefined preprocessor macros to detect
correctly. As a nice side-effect, this fixes 64-bit Android builds
cross-compiled from Windows.

KMS is no longer a platform plugin so the relevant leftover bits are
now removed.
As the introduction of the EGLDevice-based backend for eglfs shows,
using DRM/KMS is not tied to GBM, separate buffer management
approaches, like EGLStreams, work fine as well. Therefore separate KMS
from GBM and remove the EGL and GLES dependency in the tests - this
way there is nothing preventing us from using GBM without GL for
example.

In addition to the proprietary Mali Linux driver bundle from ARM, there
are a couple of semi open source alternative bundles out in the wild,
which are mostly derivatives from the sunxi-mali bundle.
The non-ARM bundles lacks the proprietary header file fbdev_window.h
which defines the fbdev_window struct. Instead, it has an equivalent
mali_native_window struct in the EGL/eglplatform.h (which in turn is
included by EGL/egl.h).
This change adds an alternative configure test which detects the non-ARM
bundles are used. It also removes the dependency on fbdev_window.h by
defining the structure ourselves, which actually makes the plugin
potentially compilable with *any* EGL SDK.
