71c100d7c0 GLSL output: Removed fixed-size buffer; fixes #769. 
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.

c142c88967 Front-ends: Non-functional: Rationalize vector and matrix swizzles. 
This reduces code duplication in a few ways, and better encapsulates
vector swizzle representation.

906cc21816 Linker: Eliminate uncalled functions, because they can be ill-defined. 
Fixes issue #610. Also provides a testing option to keep uncalled functions.

c777fc2c4c Scanning: 1) rationalize end-of-input everywhere, 2) prevent infinite loop at end-of-input, 3) use positive chars. 
Fixes issue #25. (char 255 aliased to -1 and missing tests for end of input).

1) All layers of input scanning now share a single EndOfInput value.
This avoids translation of it across layers of encapsulation.

2) Some places looking for end of line were not stopping on EndOfInput.

3) Use of "char" for the input made char values > 127 be negative numbers.
This allowed for aliasing of 255 to -1, etc.  This is fixed by using
unsigned char.

dff18a2be0 glslang: Formally track all built-in variables, right from the beginning, to enable avoiding all textual compares at any subsequent stage in the stack. (To be used in future check ins.)

8b37b04ecc glslang AST output: include global vs. temp (local) in the printed output. This only effects test results, but a future check-in is going to fix some globals.

cf0206c341 Restore r26245 and all tests and test results since 4/1: 
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.

fcb4ed054c Preprocessor: Rationalize, simplify, and correct the stack of input sources and their tokenization. This included 
- consistently dealing with EOF and its effect on error recovery (bug 11444, #1)
 - turning a simulated OO hierarchy of function pointers and typecasting into a real C++ class hierarchy
 - correctly handling '\' everywhere, in all classes of tokens, as a layer before preprocessing itself
 - conditionally handling '\n' in macro expansion input, depending on whether it is in a macro expression or not
 - delete some unused "memory cleanup" code

5134b9cf57 Track what ins/outs/uniforms are used, so that errors like "declare after use" or "can't use both XXX and YYY" can be issued. So far, used this for invariant, gl_FragColor et. al., and gl_FragCoord use before redeclaration. 
Also made all tests in testlist include linker tests.

4d6570a1b3 Fix several issues in the preprocessor: 
- macro expansion of hexidecimal numbers 
 - give errors instead of warnings/silence on extra tokens after #endif, #else, etc.
 - give errors on reserved macro name use, reuse of argument, and redefinition with different whitespace presence
 - detect and give error for all cases of #elif and #else after #else

f2ee3dd46a Add full support for uniforms with initializers, including intra-stage link validation of aggregate constant initializers. 
This included 
 - encapsulating aggregate constants
 - removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
 - adding structure type comparison for independently declared structures that still might match types

9839e2440e Unify the 8 grammar productions for declaring variables. This greatly simplifies making changes for this set of productions. 
This change also naturally picks up redeclarations of built-in arrays and the addition of the remaining linker objects of const, arrays, etc.

337dbc7d8c Add basic intra-stage linking validation for matching types and qualification of uniforms/ins/outs/globals, function body duplication, and mixing ES/non-ES shaders. 
Still need to handle arrays and built-in redeclarations, and many more rules, but this puts the basics in place.
