libsecp256k1 v0.7.0 released

We'd like to announce the release of version 0.7.0 of libsecp256k1: https://github.com/bitcoin-core/secp256k1/releases/tag/v0.7.0

This release is primarily a maintenance release. Besides many minor
internal fixes and improvements, a handful of changes affect the public
API and thus break API and ABI compatibility. The most notable changes
are:
 * The pointers secp256k1_context_static and
   secp256k1_context_no_precomp to the constant context objects are now
   const.
 * Removed previously deprecated function aliases
   secp256k1_ec_privkey_<operation> in favor of
   secp256k1_ec_seckey_<operation>.
 * Starting with this release, building with CMake is no longer
   considered experimental. Traditional GNU Autotools builds
   (./configure and make) remain fully supported.
