syntax: Refactor draw_syntax_random and add draw_syntax_texttoken ...

I realized draw_syntax_classified is the same as draw_syntax_random, so
just merge them.

Also add draw_syntax_texttoken explicitly meant to weed out cases where
token type is not set.

tests: Clean up syntax and parse code

tests: Fix name for draw_syntax_not_token

tests: Optimize and move draw_syntax_not_token to tests_syntax ...

Drawing random tokens and throwing them away was killing test
performance.

tests: Refactor getter and setter tests in to a template

tests: Move draw_token_by_value to syntax

syntax: Add peeking to SyntaxStream

tokenize: Support CR LF new line sequences

tokenize: Add more new line symbols

syntax: Drop NewLang version keyword ...

Bundling NewLang solves the issue of version compatibility.

syntax: Drop support for shebangs ...

Shebangs are useful for writing scripts, but they assume an install of
NewLang separate from the application.

I don't plan to support that, only bundling of NewLang and its scripts.

syntax: Rename SyntaxLocation's column to offset ...

We don't know anything about columns or displaying the code points in
our source file, so be clear it's an offset and not a column.

syntax: Re-organize file

tests: syntax: Rename draw_token_location to draw_syntax_location

tests: tokenize: Move syntax tests to new file
