Implemented dprintf. (Fixes #1250)
Fix #1166: Correct the amount of allocated memory for non-ascii strings in ccallFunc().
Correct typo.
Fix bug with zero-padded negative integers

The zero padding was before the sign. It should be after.
Fix bug with forced display of sign on negative integers

The negative sign was displayed twice.
Implement missing 'space' formatting flag

This flag causes space (padding) to be reserved for the sign even if the
number is positive. It is basically the same as the 'plus' flag except that
a space is displayed instead of a plus sign. The 'plus' flag takes precedence.
Fix typo in URL.
Enable WEBGL_depth_texture on GL context init. WEBGL_depth_texture is an extension that adds support for 16-bit and 32-bit integer depth formats, as well as the packed d24s8 integer depth+stencil format. See http://www.khronos.org/registry/webgl/extensions/WEBGL_depth_texture/
Mark __assert_fail as _Noreturn.

This eliminates a performance regression caused in the box2d
benchmark by switching to the musl headers.  Without this
being _Noreturn, clang / llvm generates much worse code involving
phis and extra loads.

Add more validation to the GL layer when GL_ASSERTIONS is enabled. This catches and reports situations where user code passes nonexisting or deleted GL objects to texture/program/shader/framebuffer/renderbuffer functions, and yells out explicitly that the user code is not behaving properly.
