Remove normalize and add cos instead to avoid a crash in Mac with ATI cards (angle bug 193, 202).

Also add atan and mod as it's also buggy on Mac/Win with NVIDIA cards.

Also, trying to minimize emulated functions by adding masks for fragment/vertex shaders.

called while the device is reported as lost.

Currently only eglCreateContext attempts to reset the device. This is a short term fix until the whole device lost issue can be revisited.  One of the issues here is that if any of these egl entry points are called while the device is lost (e.g. while the screen saver is on in XP) ANGLE will spin until the device comes back.

If an extension is not specified, it is disabled by default, thus a shader should fail compiling if features from that extension are used.

This change uses trivial caching to determines whether to reset shaders, the viewport, and the currently set vertex declaration. It also caches the render target desc to avoid rereading that. Serial numbers are added to vertex and index buffers, so resending those can be avoided.

These changes can give a big speedup (30% has been measured) on simple content, particularly when used directly or through pepper/native client.

Instead of iterating through every range to find the one we're looking for, instead put them all in a map and find them with that. This helps performance with index buffers that contain a bunch of different ranges.

Issue 199: invalid assertion in Surface.cpp makes debug browser crash on conformance test drawingbuffer-static-canvas-test.html

This patch fixes assertions that were wrongly asserting that only OOM errors could occur when allocating a D3D texture/surface. The drawingbuffer-static-canvas-test.html test tries a 32768x150 size, and that fails because of the too large width without being OOM.

This is implemented by adding a new compile option SH_EMULATE_BUILT_IN_FUNCTIONS.  The emulated functions are names as webgl_originalName_emu so there will never be naming conflicts.

At the moment only three functions are emulated: normalize, abs, sign.  Also, the compile option will emulate all three.  However, the mechanism to emulate only a selected subset is also imeplemented.  It can be turned on easily.

TEST=with this option, the failed test with abs.frag passes.
