Moved error-handling to a separate class - Diagnostics. We were earlier returning errors as tokens which did not work very well when error occured while parsing a preprocessor directive. Now all returned tokens are valid. Errors are reported via an abstract Diagnostics interface. Updated unit-tests with the new scheme.

Reafactored Lexer class to allow chaining. The full chain when parsing #if directive looks like this: Preprocessor -> MacroExpander -> DirectiveHandler -> MacroExpander -> DefinedFilter -> Tokenizer. This chain dynamically changes depending on the current context.
Also added an incomplete implementation of #if handling and ExpressionParser to illustrate how this design is supposed to work.

Using yy_scan_string, which flushes the old buffer does not work. GLSL requires that each input string is concatenated, but yy_scan_string treats each string individually. Added a custom YY_INPUT which maintains the continuity between each string.

Drastically simplified Input class. Now most of the heavy lifting is done by in-built yy_scan_string and yy_scan_bytes. Comment handling will be done by the lexer.

Added a catch-rule for invalid numbers.
Note that we do not need such a rule for identifiers because they will always be either terminated by a space, a punctuator, or an invalid character. Space and punctuator are both valid cases. The invalid character will be caught by another rule specifically for invalid characters. I will cover this case when I add tests for valid character set.
