TRAC #14054
The SetRenderTarget calls used in Blit::boxFilter() and Surface::swap() implicitly reset the scissor and viewport rectangles. So we need to ensure that the original rectangles get captured, and restored afterwards (the Context only keeps track of explicitly changed state).

I tested that the samples still work and that they fail as expected, but do not crash, if the attribute list argument is null.

Fixed infinite loops and buffer overflow in byte_scan when scanning for integers and floating-point numbers.
- The byte_scan and associated functions are not very well written. I tried to clean them as much as possible without re-writing the whole thing.
- Replaced lBuildFloatValue function with atof. lBuildFloatValue was returning incorrect value anyway. The only reason it was working so far because we never used that value.

I believe we don't support version 1 since we are missing things like the fixed function pipeline.

This is motivated by consistency with other EGL implementations, which return a v1 context if the EGL_CONTEXT_CLIENT_VERSION attribute is not specified.

Fixed stack overflow in CPPextension function. An arbitrary size buffer was being used for extension name. Changed it to use MAX_SYMBOL_NAME_LEN.
- Also formalized the values for MAX_SYMBOL_NAME_LEN and MAX_STRING_LEN. They were being used as if there was a confusion whether it included the NULL terminator or not.
- Fixed some minor issues with code releated to the usage of MAX_SYMBOL_NAME_LEN and MAX_STRING_LEN.

Trac #13849

Increased the maximum possible texture & renderbuffer size to 16384 (the minimum required for DX11 cards).
Limit the actual maximum texture & renderbuffer size to the maximum
that it reported by the underlying D3D9 device.

Note that creating textures and renderbuffers at the maximum size will quickly exhaust video memory!

It's crashing upon creation of the GL context, possibly the first context. Device lost would possibly explain the XP crashes. The Windows 7 box might have run out of video memory.

I also checked another couple of NULL dereference crashes.
