David Majda 3333cdd18d Position tracking: Kill the |trackLineAndColumn| option
Getting rid of the |trackLineAndColumn| simplifies the code generator
(by unifying two paths in the code).

The |line| and |column| functions currently always compute all the
position info from scratch, which is horribly ineffective. This will be
improved in later commit(s).

David Majda da8c455640 Position tracking: Make |offset|, |line| and |column| functions
This will allow to compute position data lazily and get rid of the
|trackLineAndColumn| option without affecting performance of generated
parsers that don't use position data.

David Majda 05a6bad989 Kill the |toSource| method, introduce the |output| option
Before this commit, |PEG.buildParser| always returned a parser object.
The only way to get its source code was to call the |toSource| method on
it. While this method worked for parsers produced by |PEG.buildParser|
directly, it didn't work for parsers instantiated by executing their
source code. In other words, it was unreliable.

This commit remvoes the |toSource| method on generated parsers and
introduces a new |output| option to |PEG.buildParser|. It allows callers
to specify whether they want to get back the parser object
(|options.output === "parser"|) or its source code (|options.output ===
"source"|). This is much better and more reliable API.

David Majda 3629d880d3 Make sure the |options| param passed to passes is always an object
Pass code can be simpler as a result.
