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.

On Apple Silicon, IOKit is deprecated and there will be no
matching io_service that we can query for name. Luckilly,
NSScreen got an API to fetch the display name in 10.15.
This is a blocker to get glfw running on Apple Silicon.
Fixes#1809.
Closes#1833.
This removes the final dependency on CoreVideo, using a display link to
get the refresh rate of monitors where Core Graphics report a refresh
rate of zero. Instead we now query the I/O registry directly, similarly
to what the display link does at creation.
Thanks to @OneSadCookie for pointers to this solution.
The display link query is not specific to any particular display mode
and so only needs to be done once.
The next step is to replace the display link altogether by querying
IOKit directly, which is what the display link does.
The `monitorCount` member in the `_GLFWlibrary` struct is of type `int`, so the `for` loop iterating over it should also use the type `int`.
Closes#1572.
The `size` member in the `GLFWgammaramp` struct is of type `unsigned int`, so the `for` loop iterating over it should also use the type `unsigned int`.
Closes#1541.
Window relative mouse locations provided via NSWindow and NSEvent are
based at 0,1 while screen relative locations use 0,0. Incorrect
handling of this had crept into other coordinate transformations. Note
that most of these errors canceled each other out, so the reported
positions of windows, monitors and work areas are unaffected. This
corrects the cursor position for glfwGetCursorPos and glfwSetCursorPos.
Fixes#1461.
This solution of one display link per window is far from ideal but is
still better than no solution.
As a side-effect this fixes swap interval breaking being ignored for
occluded windows on earlier versions of macOS.

This is another small step towards having GLFW play nice with other
toolkits sharing the same process, including AppKit.
Any macOS platform function that touches Cocoa must now wrap itself in
an autoreleasepool block.
Since GLFW no longer provides an autoreleasepool outside of its
functions, THIS MAY BREAK EXISTING CODE MIXING GLFW AND COCOA. Sorry!
Please add your own autoreleasepool blocks as needed.
Fixes#1107.
Closes#1114.
Allow window creation despite video mode setting failure.
Video mode setting failure is ignored the rest of the time and the
desired video mode has never been a hard constraint anyway.
This adds glfwGetWindowContentScale and glfwGetMonitorContentScale for
querying the recommended drawing scale factor for DPI-aware rendering.

This replaces CGDisplayIOServicePort with manually finding a service
port with matching vendor and product IDs. This may technically not be
the one corresponding to the display ID, but it is only used to retrieve
the human-readable make/model string.
This could be cleaned up and refined a bit by comparing more display
attributes when available, but it gets the job done.
Fixes#165.
Closes#192.
