[RDC] m2 migration, trunk broken this weekend

I'm planning on moving the RDC taglib to m2 this weekend. I'd like to
retain as much as the old distro flavor as possible since I think its
quite useful. Therefore, I think the best way to go about this is to
have a multi-module m2 build:

 * One module for the taglib jar
 * One for the examples and sample apps war file
 * One for assembling the distros (two: source and binary -- and as
before binary will contain, the above jar, war and tld, javadocs and
tlddoc)
 * Probably a parent pom for <dependencyManagement> mostly

Some experimentation involved, but I'd rather just do this on trunk.
As a result, the RDC trunk will be broken this weekend. Once I'm done
and the build is usable, I'll reply to this message. Must you need a
working base this weekend, you can get it off the PRE_M2 tag:
