Replace all the secp256k1 recovery function to validate signature with public key #3

The recovery function in secp256k1 curve cost too much resources.

In IoT constrained device, it might take longer time to run recovery function. Because there is no enough memory to keep pre-computed points on IoT device. After test secp256k1 recovery bitcoin implementation on linkit7697, it took 50 seconds to recovery one public key.

IMHO, it would be great to replace all the secp256k1 recovery function to validate signature with public key.
