This ensures that the module will not be unloaded, since GObject types
registered statically can't be reloaded. This should fix crashes with
browsers that correctly unload the plugins.

Quite tempted to delete this unmaintained and unreliable plugin, but I
can stand it not working so long as it at least stops crashing, so let's
try this first.
Hopefully mitigates bug #737932.
Instead of using the 'extension-state-changed' signal to relay errors,
use DBus's native error mechanism to inform the method caller that the
call has failed. This requires making the method actually asynchronous
so that we don't block the browser, which is stuck waiting for a reply
from the browser plugin. To ensure this, we need to modify the browser
plugin API to ensure its extesion installation method is asynchronous.
Additionally, this lets us remove the awful, broken hacks that we used
when a user clicked the "Cancel" button, replacing it by a DBus return
value.

Since we're going to move to a much more complicated (async!) solution
in a little bit, we're going to require a lot more machinery to handle
that. To help with that, let's rework invocation dispatch so that it's
more generic. Introduce a parse_args system similar to gjs_parse_args,
use X Macros to help with the repetitive parts of the method dispatch.
This shouldn't cause any API breaks, so API_VERSION should still be 4.

Instead of using g_strndup to copy the NPString that gets passed to us
by the plugin host, just use the equally-as-good NPString directly. We
still need to copy the string when passing it over DBus, as there's no
easy way to construct a string GVariant from a length-prefixed string.

While most browsers use GTK+ on GNOME in some fashion, Opera and
Konqueror do not. We need to explicitly initialize GType before
the browser plugin works properly.
While it's extremely unlikely that document.location would not be an
object in the browser setting, this check is incorrect and we could
possibly crash an NPAPI host if this is the case.

Add two new APIs, "launchExtensionPrefs" to let SweetTooth let the user
launch the extension preferences tool directly from the browser. To allow
SweetTooth to check if an extension can be configured, add a new key to
the 'metadata', 'hasPrefs', which is returned by the GetExtensionInfo/
ListExtensions DBus methods.

Some plugin hosts may have junk after the UTF8Characters that we need to strip
off. No current browsers that I know of do this, but it still helps to be
correct.
