b7d0c6037d Make dynamic module loading part of platform API
This is part of the preparations for runtime platform selection.

e31deedc99 Make timer init part of platform API
This is part of runtime platform selection because the null backend
needs the timer implementation for the current OS.

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.

Closes #544.
Fixes #1628.
Closes #1947.

111c02d74e POSIX: Remove use of deprecated gettimeofday
POSIX.1-2008 deprecated gettimeofday, which we used as a fallback if the
monotonic clock was unavailable.

This replaces that fallback with the non-monotonic real-time clock.

Because of the Gordian knot of feature test macros across Unices, this
also includes the shift from some platform source files defining
_POSIX_C_SOURCE to various values to _DEFAULT_SOURCE being defined for
all source files on Linux.  This is because -std=c99 on Linux disables
_DEFAULT_SOURCE (POSIX 2008 and extensions).

Once runtime platform selection comes in, this kind of platform-specific
preprocessor logic can be moved into the platform glue files and won't
need to be replicated by third-party build setups, but for now, sorry.

84f95a7d7f Add GLFW_X11_XCB_VULKAN_SURFACE init hint
This hint controls whether GLFW will try to use VK_KHR_xcb_surface
before falling back to VK_KHR_xlib_surface.

4ae93e0547 X11: Remove non-UTF-8 fallback paths
It seems it has not been possible to compile GLFW on systems without the
UTF-8 extensions to Xlib since a0a5cc57df
was merged five months ago.  The UTF-8 extension functions were
introduced with XFree86 4.0.2 in December 2000 and are likely widely
available at this point.

This removes the locale-dependent fallback paths and uses the UTF-8
extension functions where available.

250b94cd03 Use the correct type in a for loop
The `atomCount` variable has the type `unsigned long`,
so the `for` loop iterating over it should use the same type.

cab41529da X11: Improve non-XKB fallback for key mapping

broke the special handling of numpad keys for the non-XKB fallback path.

original behavior.

a41a58a95e X11: Fix function keys mapped to GLFW_KEY_UNKNOWN
This fixes the issue where function keys would be reported as
GLFW_KEY_UNKNOWN if XKB was available and one of the configured keyboard
layouts was Arabic.

This is only part of #1598, because the full patch removed parts of the
fallback path for when XKB is unavailable.

Closes #1598.

systems.

75294462b3 X11: Fix content scale fallback value on KDE
KDE sometimes removes the Xft.dpi resource when it would be set to the
X11 default value of 96, causing GLFW to fall back to a value calculated
from the core display sizes in pixels and mm in a desktop environment
that supports Xft.dpi.

This moves to a hardcoded fallback value of 96 on the assumption that
there are more people running KDE with 96 DPI than there are people
running desktop environments that do not support Xft.dpi.

All of this is terrible please send help.

Fixes #1578.

36f90800d8 X11: Query and keep track of Xkb group index
For users with multiple keyboard layouts configured, glfwGetKeyName
works fine only with the primary layout.  Switching layouts results in
changing the group index.  This commit querries the current group index
when initializing keyboard input and keeps track of any change to it.

As a result the scancode -> keyname mapping may change while the program
is running (needs to be documented).

Closes #1528.

3a2a97f15d X11: Fix implementation of work area retrieval
This intersects the global work area from _NET_WORKAREA with the monitor
viewport.  The monitor viewport falls back to the core display
dimensions where working RandR is missing.  The _NET_WORKAREA query is
now checked for success.  The _NET_WORKAREA extent array is now indexed
by _NET_CURRENT_DESKTOP.  The _NET_WORKAREA atom is now checked for
availability.
