This commit serves as a temporary workaround for enabling the jit until
the block customisation PR is merged in.

The EVM is now initialised with an additional configured object that
allows you to turn on debugging options.

The EVM was previously initialised and created for every CALL, CALLCODE,
DELEGATECALL and CREATE. This PR changes this behaviour so that the same
EVM can be used through the session and beyond as long as the
Environment sticks around.

Go 1.6 only prints stacks for the current goroutine by default,
but for this panic we want to see all of them.

When attempting to paste very long lines of text the REPL goes
completely fubar, never completing the paste. Removing the multiline
support "fixes" this.

Long lines of text are usually pasted when deploying contracts and as it
stands right now makes creating new contracts from the REPL impossible.

As we aren't really using the standarized SHA-3

* change gas cost for contract creating txs
* invalidate signature with s value greater than secp256k1 N / 2
* OOG contract creation if not enough gas to store code
* new difficulty adjustment algorithm
* new DELEGATECALL op code

This was requested by some users earlier but liner didn't support
it at the time. It does now.

Fixing the filename matters now because it will actually show
up in JS backtraces.

The debug package provides an RPC wrapper for glog settings and the
debugging facilities of the Go runtime. They can be triggered through
both command line flags and the IPC listener.

console: bugfix that causes the console to crash when connection to an endpoint without the personal api enabled

In order to make this happen, kill all remaining trivial uses of
common/{rlp,value}.go. The non-trivial ones have been updated earlier.

Also remove some duplication around address/index parsing.
