Protect more against error recovery of bad built-in variable redeclarations.

Fixes issue #157.

r26245: Remove "not yet complete" warning for versions 130 and 140, after tidying up a bit and adding tests.  Token pasting is the only known missing feature, and gives its own message now on use.

Implement implicit conversions of function-call arguments (both in and out) as explicit conversions in the AST, through handleArgumentConversions().

Also
 - uniformly handle EvqConstReadOnly as an input argument in a function, with 
   isParamInput() and isParamOutput() queries in TQualifier.
 - provide a makeTemporary() in TQualifier, for erasing original qualification when making a temp
 - provide a makeInternalVariable() call to make a shader variable not seen in the shader source

Fix parameter count bug in ambiguity checking for overloaded function matching under implicit conversions.

Implement 1.20 style function signature matching under implicit conversion.  This was the last key unimplemented feature of versions 120 through 330.

Add all built-in variables for all versions/profiles/stages of GLSL. Also, made more readable; declarations are cut and paste from the specs, with quotes around them.  This does not include built-in constants yet (other than MaxClipDistances), just the non-constants.

Add productions/data for about 14 qualifiers (versions 1.2 through 4.3). Fixed some case issues for rect/array keywords.
