There is a difference in interpretation of what a block count is. neo-go nodes
currently respond to this request with the latest block number which is the
same number that neoscan.io shows. However, C# nodes deliberately do add one
to this number when answering to the getblockcount request to account for the
genesis block number 0.
This patch makes us consistent with C# nodes wrt to getblockcount behaviour.
This one enables our RPC to be called from the browser if there is a
need. It's insecure and not standards-compliant, thus this behaviour is
configurable is not enabled by default. It makes our node with this workaround
enabled compatible with neo-mon monitoring.
Originally debugged by @anatoly-bogatyrev in #464.
Extend Blockchainer with one more method to spawn a VM for test runs and use
it to run scripts. Gas consumption is not counted or limited in any way at the
moment (see #424).
We already have support for running scripts inside VM CLI, so here we can just
make RPC endpoint configurable and be done with it. It also allows to use
local RPC endpoint if there is a need to.
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.
Keeping run() as the owner of all maps would mean adding at least three more
channels to keep address getters with thread-safety. But then there also is a
race between requestToWork() and run() which is way harder to solve with
channels because there are lots of possibilities for deadlocks. So rework all
of this with good old mutexes.
While at it, fix `requestCh` handling in the inner select of run, it will waste
one loop to handle it, so we should add one to the `requested`.
Fixes#445.
Wrong bits were used to represent flags which is important for contracts
created via interop. Fixes contracts failing to store things:

NewInvocationTX() returned a version number one transaction that actually
failed to pass that version down to the invocation data which lead to
serialization/deserialization inconsistency.
