Most of this is fixing functions that in some cases return a value but then
can also run to completion without returning anything. ESLint 2 catches this
where previous versions didn't. Unless there was an obvious other choice I just
made these functions return undefined at the end which is effectively what
already happens.

We weren't making the print preview browser remote for the view source
window if the view source browser was remote, causing us to fail to
show the preview.
<xul:browser>'s do not get messageManager's constructed for them unless they
have their type attribute set to "content", "content-targetable", or
"content-primary". This patch updates the view source print preview browser
with that type attribute, and also updates the PrintUtils documentation to
mention this requirement.
The -*- file variable lines -*- establish per-file settings that Emacs will
pick up. This patch makes the following changes to those lines (and touches
nothing else):
- Never set the buffer's mode.
Years ago, Emacs did not have a good JavaScript mode, so it made sense
to use Java or C++ mode in .js files. However, Emacs has had js-mode for
years now; it's perfectly serviceable, and is available and enabled by
default in all major Emacs packagings.
Selecting a mode in the -*- file variable line -*- is almost always the
wrong thing to do anyway. It overrides Emacs's default choice, which is
(now) reasonable; and even worse, it overrides settings the user might
have made in their '.emacs' file for that file extension. It's only
useful when there's something specific about that particular file that
makes a particular mode appropriate.
- Correctly propagate settings that establish the correct indentation
level for this file: c-basic-offset and js2-basic-offset should be
js-indent-level. Whatever value they're given should be preserved;
different parts of our tree use different indentation styles.
- We don't use tabs in Mozilla JS code. Always set indent-tabs-mode: nil.
Remove tab-width: settings, at least in files that don't contain tab
characters.
- Remove js2-mode settings that belong in the user's .emacs file, like
js2-skip-preprocessor-directives.
This patch does the following:
* It adds nsITransferable::Init(nsILoadContext*). The load context
might be null, which means that the transferable is non-private, but
if it's non-null, we extract the boolean value for the privacy mode
and store it in the transferable.
* It adds checks in debug builds to make sure that Init is always
called, in form of fatal assertions.
* It adds nsIDOMDocument* agruments to nsIClipboardHelper methods which
represent the document that the string is coming from.
nsIClipboardHelper implementation internally gets the nsILoadContext
from that and passes it on to the transferable upon creation. The
reason that I did this was that nsIClipboardHelper is supposed to be a
high-level helper, and in most of its call sites, we have easy access
to a document object.
* It modifies all of the call sites of the above interfaces according to
this change.
* It adds a GetLoadContext helper to nsIDocument to help with changing
the call sites.
