/*
* This file contains an implementation of the HTML parsing algorithm.
* The algorithm and the implementation are complex because HTML
* explicitly defines how the parser should behave for all possible
* valid and invalid inputs.
*
* Usage:
*
* The file defines a single HTMLParser() function, which dom.js exposes
* publicly as document.implementation.mozHTMLParser(). This is a
* factory function, not a constructor.
*
* When you call document.implementation.mozHTMLParser(), it returns
* an object that has parse() and document() methods. To parse HTML text,
* pass the text (in one or more chunks) to the parse() method. When
* you've passed all the text (on the last chunk, or afterward) pass
* true as the second argument to parse() to tell the parser that there
* is no more coming. Call document() to get the document object that
* the parser is parsing into. You can call this at any time, before
* or after calling parse().
*
* The first argument to mozHTMLParser is the absolute URL of the document.
*
* The second argument is optional and is for internal use only. Pass an
* element as the fragmentContext to do innerHTML parsing for the
* element. To do innerHTML parsing on a document, pass null. Otherwise,
* omit the 2nd argument. See HTMLElement.innerHTML for an example. Note
* that if you pass a context element, the end() method will return an
* unwrapped document instead of a wrapped one.
*
* Implementation details:
*
* This is a long file of almost 7000 lines. It is structured as one
* big function nested within another big function. The outer
* function defines a bunch of constant data, utility functions
* that use that data, and a couple of classes used by the parser.
* The outer function also defines and returns the
* inner function. This inner function is the HTMLParser factory
* function that implements the parser and holds all the parser state
* as local variables. The HTMLParser function is quite big because
* it defines many nested functions that use those local variables.
*
* There are three tightly coupled parser stages: a scanner, a
* tokenizer and a tree builder. In a (possibly misguided) attempt at
* efficiency, the stages are not implemented as separate classes:
* everything shares state and is (mostly) implemented in imperative
* (rather than OO) style.
*
* The stages of the parser work like this: When the client code calls
* the parser's parse() method, the specified string is passed to
* scanChars(). The scanner loops through that string and passes characters
* (sometimes one at a time, sometimes in chunks) to the tokenizer stage.
* The tokenizer groups the characters into tokens: tags, endtags, runs
* of text, comments, doctype declarations, and the end-of-file (EOF)
* token. These tokens are then passed to the tree building stage via
* the insertToken() function. The tree building stage builds up the
* document tree.
*
* The tokenizer stage is a finite state machine. Each state is
* implemented as a function with a name that ends in "_state". The
* initial state is data_state(). The current tokenizer state is stored
* in the variable 'tokenizer'. Most state functions expect a single
* integer argument which represents a single UTF-16 codepoint. Some
* states want more characters and set a lookahead property on
* themselves. The scanChars() function in the scanner checks for this
* lookahead property. If it doesn't exist, then scanChars() just passes
* the next input character to the current tokenizer state function.
* Otherwise, scanChars() looks ahead (a given # of characters, or for a
* matching string, or for a matching regexp) and passes a string of
* characters to the current tokenizer state function.
*
* As a shortcut, certain states of the tokenizer use regular expressions
* to look ahead in the scanner's input buffer for runs of text, simple
* tags and attributes. For well-formed input, these shortcuts skip a
* lot of state transitions and speed things up a bit.
*
* When a tokenizer state function has consumed a complete token, it
* emits that token, by calling insertToken(), or by calling a utility
* function that itself calls insertToken(). These tokens are passed to
* the tree building stage, which is also a state machine. Like the
* tokenizer, the tree building states are implemented as functions, and
* these functions have names that end with _mode (because the HTML spec
* refers to them as insertion modes). The current insertion mode is held
* by the 'parser' variable. Each insertion mode function takes up to 4
* arguments. The first is a token type, represented by the constants
* TAG, ENDTAG, TEXT, COMMENT, DOCTYPE and EOF. The second argument is
* the value of the token: the text or comment data, or tagname or
* doctype. For tags, the 3rd argument is an array of attributes. For
* DOCTYPES it is the optional public id. For tags, the 4th argument is
* true if the tag is self-closing. For doctypes, the 4th argument is the
* optional system id.
*
* Search for "***" to find the major sub-divisions in the code.

/**
* This file was partially mechanically generated from
* http://www.whatwg.org/specs/web-apps/current-work/multipage/tokenization.html
*
* After mechanical conversion, it was further converted from
* prose to JS by hand, but the intent is that it is a very
* faithful rendering of the HTML tokenization spec in
* JavaScript.
*
* It is not a goal of this tokenizer to detect or report
* parse errors.
*
* XXX The tokenizer is supposed to work with straight UTF32
* codepoints. But I don't think it has any dependencies on
* any character outside of the BMP so I think it is safe to
* pass it UTF16 characters. I don't think it will ever change
* state in the middle of a surrogate pair.
*/
/*
* Each state is represented by a function. For most states, the
* scanner simply passes the next character (as an integer
* codepoint) to the current state function and automatically
* consumes the character. If the state function can't process
* the character it can call pushback() to push it back to the
* scanner.
*
* Some states require lookahead, though. If a state function has
* a lookahead property, then it is invoked differently. In this
* case, the scanner invokes the function with 3 arguments: 1) the
* next codepoint 2) a string of lookahead text 3) a boolean that
* is true if the lookahead goes all the way to the EOF. (XXX
* actually maybe this third is not necessary... the lookahead
* could just include \uFFFF?)
*
* If the lookahead property of a state function is an integer, it
* specifies the number of characters required. If it is a string,
* then the scanner will scan for that string and return all
* characters up to and including that sequence, or up to EOF. If
* the lookahead property is a regexp, then the scanner will match
* the regexp at the current point and return the matching string.
*
* States that require lookahead are responsible for explicitly
* consuming the characters they process. They do this by
* incrementing nextchar by the number of processed characters.
