Since we're already relying on internals it makes more sense to just use
escope's function for declaring variables. We then have to remove references
from the through array and update them to point to their variables, this was
cribbed from https://github.com/eslint/eslint/blob/master/lib/eslint.js#L180

This adds more of the scripts that browser.js relies on and also makes
browser-chrome head files import the browser.js globals.
The MOZ_JSDOWNLOADS block in contentAreaUtils only seems to hide a single
function, I don't see any need to keep hiding that now we're on by default.

To properly lint XBL files we need to support things like import-globals-from
and other ESlint comment directives so we have to pass comments through to the
code blocks that ESlint parses. Unfortunately the way the XBL processor works
now is by passing a separate code block for every method/property/etc. in the
XBL and ESlint doesn't retain state across the blocks so we would have to prefix
every block with every comment. Instead this change makes us output just a
single block that roughly looks like this:
<comments>
var bindings = {
"<binding-id>": {
<binding-part-name>: function() { ... }
}
}
This has some interesting bonuses. Defining the same ID twice will cause a lint
failure. Same for the same field in a binding. The line mapping is a little
harder and there are still a few lines that won't map directly back to the
original file but they should be rare cases. The only downside is that since
some bindings have the same binding declared differently for different platforms
we have to exclude those from linting for now.

While working on turning on no-undef I discovered that the various rules we
have for defining globals are a little inconsistent in whether the files they
load recurse through import-globals-from directives and none of them imported
eslint globals directives.
I think we're better off putting all this global parsing code in a single place
rather than spread across multiple rules. Have one rule to turn it on for
parsed files and one function to load globals from other files and make them
share most of the code so we won't get inconsistent. If we find us needing to
turn on/off individual features we can figure out a way to do that in the
future.
This patch does that, the globals.js file does all global parsing with a shared
object that receives events from the AST, either through from an ESlint rule
or from a simple AST walker using estraverse.

We're attemping to find globals in JS from many places, this attempts to make
them all use the same methods. Since in some cases we're parsing new files we
can't use the eslint methods for getting the source so I've added a simple way
to convert from AST to a JS string.

Fixing some XBL files turned up some bugs in the preprocessor:
* XBL fields aren't just simple JS assignements, they are entire JS blocks which
are evaluated and the result used for the field. So we don't need eslint to
parse them as an assignment.
* XBL text can contain entities, in general just replacing every entity with a
valid JS token should retain the meaning well enough for eslint's purposes.
* Events can have names that aren't valid JS identifiers so just don't use them.
