Update browser plugins to support v2 wire protocol, and checkin some prebuilt
libraries for them. The XPI files are *not* checked in here until all
platforms are rebuilt with the changes -- otherwise, users would no longer
be able to use platforms that were left out. Log levels were changed in a
few places in the XPCOM plugin to reduce spaminess, especially in the event
the development mode server connection goes away while the page is still
running.
The Safari plugin changes have had only minimal changes, and the IE plugin
changes are completely untested. They are checked in anyway since they were
never brought up to common code changes made last year, and therefore can't
be built from trunk anyway, so they are certainly no worse off this way.
When Bob is in town next week, we will test the Safari plugin more thoroughly
(including building an install image) and get the IE plugin built/tested.
