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.

Fixes issue #610. Also provides a testing option to keep uncalled functions.

This is a replacement commit for pull request #238.

This is a design change, followed by implementation change that
A) fixes the changes caused by the design change, and
B) fixes some cases that were originally incorrect.

The design change is to not give built-in functions default precision qualification.
This is to allow the rule that the precision of some built-in functions adopt their
precision qualification from the calling arguments.  This is A above.

A consequence of this design change is that all built-ins that are supposed to have
an explicit precision qualifier must now be declared that way.  So, a lot more
built-in declarations now have precision qualifiers, just to keep things the same.
This is B above.

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.)

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.

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.

Track which extensions were enabled or required, in the intermediate representation, for reflection of the consumer.

 - print out block member types when printing a block (makes all test results change)
 - const versions of all intermediate.h type-identification methods
 - layoutSlotLocation -> layoutLocation

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.

Track whether function declarations are prototypes, and only allow at most one prototype for ES 100.

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.

 - 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)

Note: lots of test results changed due to listing the members of a block when printing types.

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

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.
