Camilla Löwy 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.

It turns out platform functions are sometimes called directly instead of
going through the public wrapper.

Camilla Löwy e0c77f71f9 Null: Make platform more conformant 
This makes the null platform behave more like an actual stub.  More
queryable state is tracked and there is even a fake monitor with one
whole fake video mode.

Camilla Löwy 56aad76b16 Add C dialect reminders to each source file 
Files built for Win32 must use C89 style declarations for compatibility
with VS 2010 and 2012, which are still supported by GLFW.
