I have compared the microb-engine sources from https://github.com/community-ssu/microb-engine to the matching Mozilla 1.9.2 sources and if we ignore the debian folder (and the patches in there), the only other differences are the change for
https://github.com/community-ssu/mic...7daa7b8e2cfa63
and the change for https://github.com/community-ssu/mic...405a7e12865ea2

Not sure if we need either of these changes in the new microb-engine or not.

In terms of the local patches applied by the build process, the list is in https://github.com/community-ssu/mic...series.microb2

We need to identify which of these changes already exist in FF24, which are no longer needed and which we still need going forward.

The biggest problem is going to be identifying all the bugs on bugzilla.mozilla.org that we may need to do something with (we found a few but finding them all will be difficult I suspect)
