compiler: support CONVERT interops
...
When result is needed to have certain type, we should have ability
to convert it, with the help of CONVERT opcode.

compiler: emit Neo.Crypto.ECDsaVerify syscall instead of CHECKSIG
...
Also change the name of `VerifySignature` interop, to match
syscall's name. It also accepts arguments in different order.

compiler: allow to declare variables of struct type
...
Previously, struct variables were initialize with VM's nil value
which is of primitive type. Thus SETITEM used for struct's field
updating wasn't working.

compiler: allow to declare slices of compound types
...
Previously this declarations were ignored which resulted
in runtime errors, because VM's nil is an element of primitive type
and can't be converted to an array.

compiler: process empty []byte{} literals as ByteArrays
...
It is wrong to count an empty byte slice as an Array.

compiler: support panic in source
...
In situations where VM's FAULT state needs to be reached,
panic function can be used. It compiles to THROW instruction.

compiler: fix a bug with FromAddress handling
...
Conversion of string to address with FromAddress is performed
at compile time so there is no need to push parameters on stack.

Add VerifySignature interop for signature verification.
It is converted to VERIFY opcode.

compiler: move it up from vm
...
It really deserves it, I think. Especially given that it doesn't have any
direct usage of `vm` package now.
