f3e2a89452 Tessellation: Implicit array sizing and consistency checking of control-shader output arrays based on layout(vertices=...).

3a4687d782 Add missing check that a function call is not using the same name as a variable hiding the function's name. Also, support version 110 separate name spaces for functions and variable names.

623833fabc Tessellation partial implementation (not ready for use yet), including:
- the built-in constants
 - built-in variable declarations, some dependent on gl_MaxPatchVertices
 - layout qualifier for vertices (shared with geometry shader max_vertices)
 - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type
 - link semantics for layout qualifiers

Still TBD:
 - patch qualifier and arrayed input handling
 - sizing of gl_out[]
 - additional semantic checking
 - supporting the extension on version 150

a4351c55e8 More subtle checking for redeclarations:
- 300 doesn't allow built-in overload, while 100 does, while neither allows redefining
 - block name can't be reused for block name within the same interface 
   (though, the spec. isn't clear about that, it's easier than verifying member matches, will file bug on it)
