Tibor Bősze 6b8a24918e rpcserver: Improve JSON-RPC compatibility 
Avoid compatibility issues with software that relies on the behavior of
bitcoind's JSON-RPC implementation.

The JSON-RPC 1.0 spec defines that notifications must have their "id"
set to null and states that notifications do not have a response.

A JSON-RPC 2.0 notification is a request with "json-rpc":"2.0", and
without an "id" member. The specification states that notifications
must not be responded to. JSON-RPC 2.0 permits the null value as a
valid request id, therefore such requests are not notifications.

Bitcoin Core serves requests with "id":null or even an absent "id", and
responds to such requests with "id":null in the response.

Btcd does not respond to any request without and "id" or with "id":null,
regardless the indicated JSON-RPC protocol version.

In order to avoid compatibility issues with software relying on
Core's behavior, this commit implements "quirks mode" as follows:
 - quirks mode can be enabled via configuration (disabled by default)
 - If no JSON-RPC version is indicated in the request, accept and
respond to request with "id":null
 - If no JSON-RPC version is indicated in the request, accept and
respond to requests without an "id" member
 - In both cases above, use "id":null in the response
 - Do not respond to request without an "id" or with "id":null when
JSON-RPC version is indicated in the request (process as notification)

; The directory to store data such as the block chain and peer addresses. The
; block chain takes several GB, so this location must have a lot of free space.
; The default is ~/.btcd/data on POSIX OSes, $LOCALAPPDATA/Btcd/data on Windows,
; ~/Library/Application Support/Btcd/data on Mac OS, and $home/btcd/data on
; Plan9. Environment variables are expanded so they may be used. NOTE: Windows
; environment variables are typically %VARIABLE%, but they must be accessed with
; $VARIABLE here. Also, ~ is expanded to $LOCALAPPDATA on Windows.

; Use testnet.
; testnet=1
; Connect via a SOCKS5 proxy. NOTE: Specifying a proxy will disable listening
; for incoming connections unless listen addresses are provided via the 'listen'
; option.
; proxy=127.0.0.1:9050
; proxyuser=
; proxypass=
; The SOCKS5 proxy above is assumed to be Tor (https://www.torproject.org).
; If the proxy is not tor the following may be used to prevent using tor
; specific SOCKS queries to lookup addresses (this increases anonymity when tor
; is used by preventing your IP being leaked via DNS).
; noonion=1
; Use an alternative proxy to connect to .onion addresses. The proxy is assumed
; to be a Tor node. Non .onion addresses will be contacted with the main proxy
; or without a proxy if none is set.
; onion=127.0.0.1:9051
; onionuser=
; onionpass=
; Enable Tor stream isolation by randomizing proxy user credentials resulting in
; Tor creating a new circuit for each connection. This makes it more difficult
; to correlate connections.
; torisolation=1
; Use Universal Plug and Play (UPnP) to automatically open the listen port
; and obtain the external IP address from supported devices. NOTE: This option
; will have no effect if exernal IP addresses are specified.
; upnp=1
; Specify the external IP addresses your node is listening on. One address per
; line. btcd will not contact 3rd-party sites to obtain external ip addresses.
; This means if you are behind NAT, your node will not be able to advertise a
; reachable address unless you specify it here or enable the 'upnp' option (and
; have a supported device).

; ******************************************************************************
; Summary of 'addpeer' versus 'connect'.
;
; Only one of the following two options, 'addpeer' and 'connect', may be
; specified. Both allow you to specify peers that you want to stay connected
; with, but the behavior is slightly different. By default, btcd will query DNS
; to find peers to connect to, so unless you have a specific reason such as
; those described below, you probably won't need to modify anything here.
;
; 'addpeer' does not prevent connections to other peers discovered from
; the peers you are connected to and also lets the remote peers know you are
; available so they can notify other peers they can to connect to you. This
; option might be useful if you are having problems finding a node for some
; reason (perhaps due to a firewall).
;
; 'connect', on the other hand, will ONLY connect to the specified peers and
; no others. It also disables listening (unless you explicitly set listen
; addresses via the 'listen' option) and DNS seeding, so you will not be
; advertised as an available peer to the peers you connect to and won't accept
; connections from any other peers. So, the 'connect' option effectively allows
; you to only connect to "trusted" peers.
; ******************************************************************************

; You may specify each IP address with or without a port. The default port will
