bafece4cf7 Update Wayland remarks for glfwCreateWindow
The backend has improved somewhat and support among compositors for some
protocols have improved to the point that they can be relied upon.

2b3f919b60 Wayland: Add support for fractional scaling
This adds basic support for fractional-scale-v1.

Note that this introduces a potential discrepancy between window and
monitor content scales.

a9cc7c7260 Add GLFW_SCALE_FRAMEBUFFER window hint
This adds the GLFW_SCALE_FRAMEBUFFER window hint, enabling control of
framebuffer scaling across Wayland and macOS.  On macOS, this window
hint is a new name for GLFW_COCOA_RETINA_FRAMEBUFFER, and both hint
names will modify the same hint.

This is now a more symmetric counterpart to GLFW_SCALE_TO_MONITOR and,
weirdly, they each apply neatly to half of the supported platforms.

This commit is mostly documentation updates to better integrate and
contrast these two scaling mechanisms.

a360198f8f Wayland: Implement glfwFocusWindow
This implements window focus requests via the xdg-activation-v1
protocol.  These requests will likely only work when another window of
the same application already has input focus, but that isn't unlike the
behavior of other platforms.

The GLFW_FEATURE_UNAVAILABLE error has been removed from this function
for now.

d2b88cf7ab Update documentation for native access errors
The GLFW_PLATFORM_UNAVAILABLE error was not listed for those native
access function that can emit it.

The order of errors for many functions in glfw3native.h did not match
the order used in glfw3.h.

The documentation for GLFW_PLATFORM_UNAVAILABLE was a little bit terse.

9959dc69ca Improve documentation relating to key tokens
Shifted the documentation away from the term 'named keys' as something
different than keys that glfwGetKeyName will return a name for.  The
already existing term 'key token' should now be used to refer to the
GLFW_KEY_* constants.

The associated term 'named mouse button' was also replaced with
'supported mouse button'.

The parts explaining which key tokens will return a valid scancode from
glfwGetKeyScancode have hopefully been clarified.  This issue was
reported in #2055.

The GLFW_KEY_UNKNOWN constant has been moved out of the list of key
tokens to simplify and hopefully clarify the related documentation.

Various other keyboard key related edits were made, hopefully resulting
in improvements.

Documentation: only named keys generate synthetic key releases
The current wording states that all keys have synthetic key release
events generated after focus is lost, but keys that aren't named
don't have any state held, so no such events are generated for them.

The new wording clarifies that only named keys have the events generated
for them.

fbdb53b9ca Wayland: Add initial support for libdecor
This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.

Where available, the libdecor library is loaded at init and becomes the
preferred method for window decorations.  On compositors that support
XDG decorations, libdecor in turn uses those.  If not, libdecor has
a plug-in archtecture and may load additional libraries to either use
compositor-specific decorations or draw its own.

If necessary, support for libdecor can be disabled with the
GLFW_WAYLAND_LIBDECOR init hint.  This is mostly in case some part of
the dynamic loading or duplication of header material added here turns
out to cause problems with future versions of libdecor-0.so.0.

0f9a9578f3 Add window hints for initial position
This adds window hints for the initial position, in screen coordinates,
of a window.  The special value GLFW_ANY_POSITION means the window
manager will be allowed to position the window.

It is not possible to set window positions on Wayland and GLFW will
always behave as if these hints are set to GLFW_ANY_POSITION.

This adds a window hint string for the xdg_toplevel::app_id, which is

05f6c13d11 Add support for GLFW_NATIVE_INCLUDE_NONE macro
By default, the glfw3native.h header will include the platform-specific
headers necessary for the return types of GLFW native access functions.

Sometimes it is preferrable to declare those types

This commit adds support for the GLFW_NATIVE_INCLUDE_NONE macro, which
when defined disables the inclusion of all platform-specific headers.

ce85c7dcaf Fix GLAPIENTRY not being defined for native access
This is a follow-up to 535c3ce632.

That commit made glfw3native.h undefine GLAPIENTRY whenever
GLFW_EXPOSE_NATIVE_GLX or GLFW_EXPOSE_NATIVE_OSMESA was defined, on the
assumption that it was glfw3.h that had defined GLAPIENTRY.

If gl.h or an extension loader header has been included before glfw3.h,
then it has defined inclusion guards preventing GLAPIENTRY from being
defined later when the GLX or OSMesa header includes gl.h.

This commit ensures GLAPIENTRY is only undefined if glfw3.h defined it.

535c3ce632 Fix GLAPIENTRY redefinition warning
On a Unix system, if you define GLFW_INCLUDE_NONE and
GLFW_EXPOSE_NATIVE_GLX, then include glfw3.h and glfw3native.h, you will
get a redefinition warning for GLAPIENTRY.

The glfw3.h header defines GLAPIENTRY as a service for OpenGL related
headers that assume it's already defined.  However, glx.h includes gl.h,
which defines GLAPIENTRY unconditionally.

If not for Hyrum's law, the better solution would have been not to
define GLAPIENTRY if GLFW_INCLUDE_NONE is defined.

56a4cb0a3a Add runtime platform selection
This adds compile-time support for multiple platforms and runtime
detection of them.  Window system related platform functions are now
called from shared code via the function pointer struct _GLFWplatform.

The timer, thread and module loading platform functions are still called
directly by name and the implementation chosen at link-time.  These
functions are the same for any backend on a given OS, including the Null
backend.

The platforms are now enabled via CMake dependent options following the
GLFW_BUILD_<platform> pattern instead of a mix of automagic and ad-hoc
option names.  There is no longer any option for the Null backend as it
is now always enabled.

Much of the struct stitching work in platform.h was based on an earlier
experimental branch for runtime platform selection by @ronchaine.

Every platform function related to windows, contexts, monitors, input,
event processing and Vulkan have been renamed so that multiple sets of
them can exist without colliding.  Calls to these are now routed through
the _glfw.platform struct member.  These changes makes up most of this
commit.

For Wayland and X11 the client library loading and display creation is
used to detect a running compositor/server.  The XDG_SESSION_TYPE
environment variable is ignored for now, as X11 is still by far the more
complete implementation.

22b586b3d8 Add pluggable heap allocator
This adds the glfwInitAllocator function for specifying a custom memory
allocator to use instead of the C runtime library.

The allocator is a struct of type GLFWallocator with fields
corresponding to malloc, realloc and free, while the internal API
corresponds to calloc, realloc and free.

Heap allocation calls are filtered before reaching the user-provided
functions, so deallocation of NULL and allocations of zero bytes are not
passed on, reallocating NULL is transformed into an allocation and
reallocating to size zero is transformed into deallocation.

The clearing of a new block to zero is performed by the internal
calloc-like function.
