c39153756a rpcsrv: carefully store Oracle service
And simplify atomic service value stored by RPC server. Oracle service can
either be an untyped nil or be the proper non-nil *oracle.Oracle.
Otherwise `submitoracleresponse` RPC handler doesn't work properly.

6e990f39de cli/node: Fix deadlock produced by instant RPC service start
If `StartWhenSynchronized` is unset in config, `node` command runs RPC
service instantly. Previously there was a ground for deadlock. Command
started RPC server synchronously. According to server implementation, it
sends all internal failures to the parameterized error channel. Deadlock
occured because main routine didn't scan the channel.

Run `rpcsrv.Server.Start` in a separate go-routine in `startServer`.
This prevents potential deadlock caused by writing into unread channel.

Fixes #2896.

465d3f43d2 services/rpcsrv: Wait for subscription process to complete when stopped
Previously RPC server shutdown procedure listened to the execution
channel and stopped at the first element that arrived in the queue. This
could lead to the following problems:
 * stopper could steal the execution result from subscriber
 * stopper didn't wait for other subscription actions to complete

Add dedicated channel to `Server` for subscription routine. Close the
channel on `handleSubEvents` return and wait for signal in `Shutdown`.

f8227aa5f7 services/rpcsrv: Fix potential shutdown deadlock of RPC server
Previously RPC server could never be shut down completely due to
some start precondition failure (in particular, inability to serve HTTP
on any configured endpoint). The problem was caused by next facts:
 * start method ran subscription routine after HTTP init succeeded only
 * stop method blocked waiting for the subscription routine to return

Run `handleSubEvents` routine on fresh `Start` unconditionally. With
this change, `Shutdown` method won't produce deadlock since
`handleSubEvents` closes wait channel.

c880873105 core: improve documentation to SetOracle/SetNotary
I've carefully checked the way how new service can be added to the
Blockchain instance or to be removed from it. Current implemention
of SetNotary and SetOracle methods doesn't contain dangerous code,
and native contracts have atomic values everywhere where service
is stored.

Current implementation of Notary, Oracle and StateRoot services'
reload/disabling/enabling on SIGUSR1 is safe and doesn't require
any adjustment.

This commit closes #2944, it's not a bug in the code, it's just
stale documentation.

ee4b8f883b core: check signers of on-chained conflict during new tx verification
During new transaction verification if there's an on-chain conflicting
transaction, we should check the signers of this conflicting transaction.
If the signers intersect with signers of the incoming transaction, then
the conflict is treated as valid and verification for new incoming
transaction should fail. Otherwise, the conflict is treated as the
malicious attack attempt and will not be taken into account;
verification for the new incoming transaction should continue.
