Godeps, rpc: switch back to package npipe

This adds compatibility with Go 1.7, where context has
moved into the standard library.

The named pipe implementation from go-winio has some issues
that need to be addressed before we can use it again.

eth/downloader: return invalid chain (peer drop) on import fails

Revert faulty DAO soft-fork

This reverts commit 1e3a7d4f.

core: update the DAO soft fork proposal to the final block

DAO soft-fork

web3ext: Remove old natspec Admin_JS stubs

This stops them from showing up on the javascript console.

build: add ci.go, use it everywhere

The new build script, ci.go, replaces some of the older shell scripts.
ci.go can compile go-ethereum, run the tests, create release archives
and debian source packages.

This implements a generic approach to enabling soft forks by allowing
anyone to put in hashes of contracts that should not be interacted from.
This will help "The DAO" in their endevour to stop any whithdrawals from
any DAO contract by convincing the mining community to accept their code
hash.
