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.

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".
