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.

directories. People with pkgsrc can add the directory through CGO_CFLAGS
instead.

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.

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`.
