Merge lp:~mordred/drizzle/drizzled-as-lib into lp:~drizzle-trunk/drizzle/development

[Monty Taylor]

Changed the build to build most of the code as a shared lib and then link that into the drizzled binary. This does _NOT_ make it any sort of embedded server or make the lib particularly useful - except for pre-linking plugins against for link-time symbol resolution checking. It will also make it easier for us to start applying visibility structures to objects. YAY ABI!

[Eric Day (eday)]

Looks great! Excited to get the new main.cc whittled down even more.

review: Approve
