02356b36d6 crypto/secp256k1: remove dependency on libgmp
Turns out we actually don't need it, USE_NUM_NONE works
because we also set USE_FIELD_INV_BUILTIN.

e344e1d490 crypto/secp256k1: drop pkgsrc paths from CFLAGS
They cause compiler warnings for people who don't have these
directories. People with pkgsrc can add the directory through CGO_CFLAGS
instead.

1b29aed128 crypto/secp256k1: verify recovery ID before calling libsecp256k1
The C library treats the recovery ID as trusted input and crashes
the process for invalid values, so it needs to be verified before
calling into C. This will inhibit the crash in #1983.

Also remove VerifySignature because we don't use it.

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`.
