Refactor Autofill parsing code. Most notably, add a helper class for parsing with lookahead.

* Adds an AutofillScanner class to help with lookahead parsing.
* Remove the NULL-termination from FormStructure's fields vector
* Remove some redundant DCHECKs
* Refactor PersonalDataManager::ImportFormData() to take a single form, not a vector of forms.
* Move EmailField class to its own file
* Remove some obsolete billing/shipping address distinguishing code
* Refactor the code to remove the really wonky FormFieldSet() class
* Refactor some interfaces to take |size_t| rather than |int|
* Remove some unused fields from FormStructure
* Const-correctness

BUG=none
