Reframe the preprocessor as a C++ class, with instances, removing all C code, removing all global variables.  Upgrade bison version to pass a parse context on through to the preprocessor.  All the basic things to make something thread safe.

Eliminate flex as the GLSL lexical analyzer, going from two nested lexical analyzers down to one, leaving just the preprocessor's lexical analysis.  A new layer replaces it, to translate from the preprocessor's view of tokenization to glslang's view of tokenization.

Also:
 - change source locations from an int to TSourceLoc (shader number, line number) throughout
 - various improvements to the preprocessor

Rationalize naming/access to current thread-local-storage scheme.  However, the preprocessor tokenizer is not thread-safe, so this may all change.

Also adding missing test.

1) Don't propagate precision of built-in function arguments to return type when return type is bool (e.g., isnan).
2) Check an additional path for missing default precision qualification, except allow built-in declarations to pass the check.

Use the default of "smooth" for interpolation qualification for vertex outs and fragment ins (rather than all fragment IO).

Support line-continuation (backslash before newline) for tokens and one-line comments in the preprocessor.

Add scanner that can find '#version' across an array of non-null terminated, length-based, strings.  Handle the ES error where #version is not the first thing found, while still supporting desktop behavior, and more generally support length-based multiple strings for a single shader.

Create linkage symbol nodes in the AST so a linker has access to all global objects that were declared, for error checking, etc.  Use it now for all ins/outs/uniforms as well as gl_VertexID and gl_InstanceID.

Also fixed a confusing name and added more 'const'.

Fix bug of accidentally overriding initial layout location with 0, which does not mean no location.  Added in/out structure tests.

Track separate precision defaults for each kind of sampler, give initial defaults as per spec. Also make fragment floats have no default.  Modify/add tests to adapt to these changes.

Simply compile-time error handling: mostly removed the need to test an error occurred and the need to call recover().

Block/structure fixes: Merge qualifiers with multiple declarators, handle arrays of blocks, more semantic checks for what's allowed.
