Mercurial forests for JDK 8

[mark.reinhold at oracle.com]

I'm in the process of creating the master forest, which will be rooted at
http://hg.openjdk.java.net/jdk8/jdk8.

What other group/integration forests do we want to have?

JDK 7 has 21 (!) separate forests.  Only these have been updated in 2011:

    2d
    awt
    build
    deploy
    hotspot
    hotspot-comp
    hotspot-gc
    hotspot-rt
    l10n
    swing
    tl

The VM team would prefer to host their group and integration forests
under the HSX Project since they deliver into multiple JDK release
trains, so unless there are other suggestions I'll just create these:

    2d
    awt
    build
    deploy
    l10n
    swing
    tl

Comments?
