9c1280b225 Use extension framework to enable #include directive. 
This patch introduces a new extension, GL_GOOGLE_include_directive,
to enable support #include directives. It depends on the extension
GL_GOOGLE_cpp_style_line_directive.

5011fbebc3 Extend the syntax of #line and __FILE__ to support filename strings. 
According to the GLSL spec, the second parameter to #line should be
an integer source string number and __FILE__ will be substituted
with the integer source string number currently processed. This
patch extends the syntax of #line and __FILE__. Now #line accepts
as the second parameter a filename string quoted by double quotation
marks. And if such a #line is set, __FILE__ will be substituted with
the currently set filename string. The implementation is done via
introducing a new extension GL_GOOGLE_cpp_style_line_directive using
the extension framework.

The purpose is to support cpp-style #line directives, which is
required by #include.

93deac5295 Fix incompatibility with <GL/glext.h> 
New extensions in glext.h follow the pattern:

    #ifndef GL_ARB_texture_rectangle
    #define GL_ARB_texture_rectangle 1
    #define GL_TEXTURE_RECTANGLE_ARB          0x84F5
    #define GL_TEXTURE_BINDING_RECTANGLE_ARB  0x84F6
    #define GL_PROXY_TEXTURE_RECTANGLE_ARB    0x84F7
    #define GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB 0x84F8
    #endif /* GL_ARB_texture_rectangle */

Versions.h tries to declare:

    const char* const GL_ARB_texture_rectangle = "GL_ARB_texture_rectangle";

Which means, if you've included glext.h before Versions.h, that the
compiler will see "const char* const 1 = ...", and rightly refuse to
continue.

The ham-fisted approach taken here is to rename the variables in
Versions.h with a leading underscore.  This does sort of undermine the
comment about "better to have the compiler do spelling checks", but.

edadf45605 glslang: Add API override of version and profile for testing purposes. From Lei Zhang <antiagainst@google.com>. 
Add defaultProfile and forceDefaultVersionAndProfile into shader
compilation interface.

forceDefaultVersionAndProfile allows us to force parsing the input
shaders using defaultVersion and defaultProfile, regardless of
the #version directive in input shaders.

These two parameters enables us to programmatically invoke glslang
but specify version and profile from somewhere else like command
line.
