web3: updated 0.9.1

The code in config.go is unused. The main reason for removing it is to
get rid github.com/rakyll/goini in Godeps (it has no license).

I forgot to update one instance of "go-ethereum" in commit 3f047be5.

cmd/core,xeth: removed unneeded states & added batch writes

all: license fixes

cmd, core, eth, ethdb: cache flag to allocate memory for db internal use

core: fix an RLP encoding data race due to deep struct copy

All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

crypto/curve.go is not our code and has its own license. This commit
excludes it in update-license.go and removes our GPL header.
