5bd666b786 vm: return NOP as current instruction for just loaded VM 
Before:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (PUSH0)

After:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (NOP)

I think NOP is a little less scary.

7b0c2781d2 vm: expand instruction list with commands from current VM spec 
Current NEO documentation lists them:
https://docs.neo.org/docs/en-us/tooldev/advanced/neo_vm.html

CALL_* instructions were left out because of conflict with golint (but they're
removed in NEO 3.0 anyway, so wasting time on them makes no sense).

Update autogenerated instruction_string.go accordingly.

e537dc9ee4 keys: improve publick key checks with a check against P 
ANSI X9.62 says that if x or y coordinate are greater than or equal to
curve.Params().P, the conversion should return an error (see ANSI X9.62:2005
Section A.5.8 Step b, which invokes Section A.5.5, which does the check and
rejects when x or y are too big.

See https://github.com/golang/go/issues/20482 for more details.

2c3e92923f keys: simplify error handling for PublicKey() and associated 
PublicKey() for PrivateKey now just can't fail and it makes no sense to return

f0fbe9f6c9 crypto: drop home-grown elliptic crypto, use crypto/elliptic 
As NEO uses P256 we can use standard crypto/elliptic library for almost
everything, the only exception being decompression of the Y coordinate. For
some reason the standard library only supports uncompressed format in its
Marshal()/Unmarshal() functions. elliptic.P256() is known to have
constant-time implementation, so it fixes #245 (and the decompression using
big.Int operates on public key, so nobody really cares about that part being
constant-time).

New decompress function is inspired by
https://stackoverflow.com/questions/46283760, even though the previous one
really did the same thing just in a little less obvious way.

0b884b92b3 crypto: use PrivateKey to generate a key pair 
It makes no sense to provide an API for throw-away public keys, so obtain it
via a new real keypair generation where appropriate (and that's only needed
for testing).
