Pavol Rusnak 3f07afbbd2 remove elliptic.P224 usage 
Fedora/RedHat distros comply with US patent law and remove this curve,
which makes it impossible to run ethereum with distro provided Golang.

File crypto/ecies/README claims it is unsupported anyway.

Felix Lange 3f047be5aa all: update license headers to distiguish GPL/LGPL 
All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

Felix Lange f4acdea402 crypto: fix license of curve.go 
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.

Noel Maersk 958c04e79a doc: crypto/secp256k1 GMP dependency package name. 
Linux build documentation is mostly geared towards Ubuntu 14.04 (LTS).
Appropriate package is called `libgmp-dev` there.

Note that on pristine installations building `geth` with godep will
fail because this header is missing. This is not documented in the
top-level README, but is on the wiki:

https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu#building-geth-command-line-client

That page recommends `libgmp3-dev`, which ATM provides same version
as `libgmp-dev`.
