8d4dd2d2e1 vm: move opcodes into their own package 
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

03ff2976ed io: refactoring for using WriteVarBytes instead of WriteLE 
goal is to be consistent with C# implementation.
For writing []byte WriteBytes used and for byte - WriteVarByte.

e319c6c638 cli: move avm inspect from vm to contract command 
Make inspect work with avms by default and with go files if told so. In the
end this makes our CLI interface more consistent and usable. Drop useless
CompileAndInspect() compiler method along the way.

e2bfff8666 vm: removed mute mode and pushed logging to upper lvl 
VM should be responsible for code execution and in case anyone interested in additional logging or errors they could handle them like we do it iin cli.

dca332f333 vm: use new Context.Next() to properly dump programs 
Fix #295, deduplicate code and add `inspect` parameter to the vm command to
dump AVMs (`contract inspect` works with Go code).

4ccda04eea compiler: fix string/numbers equality/inequality gen again 
Unfortunately d58fbe0c88 didn't really fix the
problem because tinfo.Type (the expression resulting type) actually is a bool
and we need to check its parameters. Also, there is need to fix the NEQ
operation.

a1e3655560 interop: move into pkg/interop, replace pkg/vm/api 
neo-storm has developed more wrappers for syscall APIs, so they can and should
be used as a drop-in replacement for pkg/vm/api. Moving it out of vm, as it's
not exactly related to the VM itself.

7cd91610df compiler: quick and dirty inspection fix for JMP instrs 
These were interpreted completely wrong, they actually have two next bytes
indicating an offset. This patch is a quick fix, actually more work is needed
here to properly display various instructions.

810f096811 compiler: change codegen to emit NUMEQUAL instead of EQUAL 
This is wrong, see issue #294, but it makes our VM tests work (as VM is
missing EQUAL implementation), so until #294 is properly resolved we're better
have this kind of wrong code generation.
