1f2d76a1c2 compiler: fix manifest method offset
While optimizing jumps, old offsets should be compared
with the method offset before optimization, not with
the constantly changing value.

f8d5c40928 compiler: do not DROP return value with type assertion
The same problem as with IF. Example:

```
func foo() interface{} {
    ...
}

func Main() int{} {
   return foo().(int)    <--- panic here
}
```

dbce3c9a19 compiler: do not DROP unary expression value inside IF stmt
We dropped values from such calls because they where marked as unused
(consequently, were followed by DROP instructions). Example:

if !foo() {    <--- panic here
    ...
}

This commit prevents the following runtime error during script execution:
```
"error encountered at instruction ** (NOT): runtime error: invalid memory address or nil pointer dereference"

```

fe1f0a7245 core: introduce CheckReturnState constants
At the moment we should have 3 possible options to check return state
during vm context unloading:
	* no check
	* ensure the stack is empty
	* ensure the stack is not empty

It is necessary to distinguish them because new _deploy method shouldn't
left anything on stack. Example: if we use _deploy method before some
ordinary contract method which returns one value. Without these changes
the contract invocation will fail due to 2 elements on stack left after
invocation (the first `null` element is from _deploy, the second element
is return-value from the ordinary contract method).

38a22b44b2 network: try connecting to seeds indefinitely, use them with 0 pool
If the node is to start with seeds unavailable it will try connecting to each
of them three times, blacklist them and then sit forever waiting for
something. It's not a good behavior, it should always try connecting to seeds
if nothing else works.

097ef2a731 core: copy storage item key in simple.GetStorageItems
Related to #1468, ported from #1475.

We should copy the key to avoid bytes substitution. Otherwise there's a
chance that at the end of dao.Store.Seek(...) execution some keys won't
be the same as the original keys found inside saveToMap function because
storage.Seek can guarantee that provided key and value are only valid
until the next `f` call.

c8ba155d47 server: don't always Sprintf params for logger
Add Stringer to Params, if we're not printing Debug messages (which usually is
the case), it won't be called at all. Micro-optimization.
