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.

Fixes#1628.
Closes#1947.
The outer glfwUpdateGamepadMappings function is now bypassed when
parsing the default gamepad mappings. The data in mappings.h does not
contain any comments or line breaks. Also this is done before joystick
support has been initialized, so there is no need to look for matching
devices.
Finally, the array of default mappings is pre-allocated. This has no
measurable performance impact but does generate a lot of calls, which
won't be nice for a user provided custom allocator to deal with.
Because there are controllers in the wild using the same hardware ID
despite having different numbers of buttons and axes, an error message
was triggered that was only expected for a corrupted mapping database.
This removes the error for now, in preparation for better error handling
for gamepad mappings overall.
Fixes#1763.
This makes joystick support initialize the first time a joystick
function is called, including those gamepad functions that are layered
on top of joystick functions.

This renames 'raw input' to 'raw mouse motion' as there are other kinds
of raw input. The update path is restructured to avoid reinitializing
all of disabled cursor mode. Modification of shared state is moved out
into shared code. Raw mouse motion is disabled by default for
compatibility.

Older versions did not provide fmin or fmax. This adds internal
versions of fminf and fmaxf that should not be confused with
standards compliant implementations.
This adds support for the + and - and ~ input modifiers for joystick
axes. It also changes how joystick axes are translated to buttons to
more closely match SDL 2.0.7.
Output modifiers are still not supported but have not yet been seen in
the wild.
This adds the GLFW_MOD_CAPS_LOCK and GLFW_MOD_NUM_LOCK modifier bits.
Set the GLFW_LOCK_KEY_MODS input mode to enable these for all callbacks
that receive modifier bits.
Fixes#946.
If the expected constants are defined in hexadecimal in the header then
the error string should also use hexadecimal.

This moves the buttons-as-hats logic to shared code and adds the
GLFW_JOYSTICK_HAT_BUTTONS input mode as a way to disable this legacy
behavior.
Fixes#889.
This merges the public part of the glfwGetJoystickHats work by
@IntellectualKitty. The implementation needs replacing due to
refactoring in preparation for gamecontrollerdb support.
Closes#906.
