Remove leftover things from chromeos
chore(net-wireless/*): remove everything

Lets not worry about having coreos support wireless for now :)
chore(dev-java/icedtea6-bin): remove
chore(dev-embedded): remove uneeded ebuilds
chore(x11-drivers): remove unneeded ebuilds
fix(coreos-base/coreos): remove crosh

crosh isn't really needed for coreos and particularly we don't need the
dependency on x11. Kill it!
Merge pull request #56 from philips/remove-crosh

fix(coreos-base/coreos): remove crosh
fix(coreos-base/vboot_reference): put into bumpable format

use the symlink trick to make this ebuild bumpable

CoreOS has its own GPT guids now. Use them.

Bump vboot reference
chore(x11-*): remove all x11 packages

we don't need x11 anymore after remove crosh. Dump all of these ebuilds.
chorse(coreos-base/hard-host-depends): remove m17n

remove m17n means that we no longer depend on x11 in the sdk.

Make this ebuild use the coreos github projects not Google's

Pair down ebuilds
Merge pull request #58 from philips/remove-all-x11

chore(x11-*): remove all x11 packages
fix(cros-workon.eclass): Add support for projects in src/platform

We no longer have any correlation between ebuild category and whether
the local checkout can be found in src/platform or src/third_party.
Instead provide a new variable to manually specify which it should be.
As-is it isn't possible to build local changes in src/platform trees.
bump(coreos-base/cros-devutils): update to latest code

This pulls in recent changes to cros_generate_update_payload
bump(coreos-base/update_engine): Update stable release to latest code

The stable ebuild hasn't been bumped to include quote a lot of recent
work yet so lets do that. :)
Merge pull request #59 from marineam/updates

coreos-base/update_engine + cros-workon.eclass
fix(profiles): Move the mirror list from make.conf to profiles.

Another piece of migrating as much as possible into our profiles, this
should fix a current error blocking bootstrap_sdk builds.
