When an include directive is recognized by the preprocessor, it
executes a callback on the filepath argument to obtain the file
contents. That way the compilation client can deal with the file
system, include paths, etc.
Currently only accepts quoted filepaths -- no angle brackets yet.
Expose a new method setStringsWithLengthsAndNames() in the interface
which allows the caller to set descriptive names for source strings.
These names can be used in error messages.
According to the GLSL spec, the second parameter to #line should be
an integer source string number and __FILE__ will be substituted
with the integer source string number currently processed. This
patch extends the syntax of #line and __FILE__. Now #line accepts
as the second parameter a filename string quoted by double quotation
marks. And if such a #line is set, __FILE__ will be substituted with
the currently set filename string. The implementation is done via
introducing a new extension GL_GOOGLE_cpp_style_line_directive using
the extension framework.
The purpose is to support cpp-style #line directives, which is
required by #include.
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.
SourceLineSynchronizer is added for keeping track of the last
line number and output newlines appropriately if we switch to
a new line in the preprocessor.
The current line number for the #line directive should be passed
in as parameter to the line directive callback. Without it, we
don't know how many empty lines we should output.
The line argument passed into the lineCallback function is the
literal value of the first argument of the #line directive.
lastLine in DoPreprocessing() should be updated taking into
consideration the different definitions for #line between specs.
Add a test to reveal the bug.
Add defaultProfile and forceDefaultVersionAndProfile into shader
compilation interface.
forceDefaultVersionAndProfile allows us to force parsing the input
shaders using defaultVersion and defaultProfile, regardless of
the #version directive in input shaders.
These two parameters enables us to programmatically invoke glslang
but specify version and profile from somewhere else like command
line.

r26192: Link-time sizing of implicitly-sized arrays and handling of anonymous blocks containing implicitly-sized members. Also changed "__anon" to "anon@" and encapsulated it.
r26240: Solidify the sharing of struct and array information between nodes and variables: A single copy now allows for simultaneously setting array size for all effected nodes and symbols of a given type. This allowed removal of ioArrayNodeResizeList and makes nodes of implicitly sized arrays know the final size.
r26241: Fix g++ issue with wanting non-const iterator.

- 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

- 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)

- 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

- the new C++ style interface now stands on its own, with the addition of glslang::InitializeProcess() and glslang::FinalizeProcess()
- more "global" pool names from a decade ago are fixed to be thread names
- StandAlone.cpp fully uses one of the old-style interface or new C++ style interface
