ISSUE-130: Enable variety of protocols (e.g. UPnP, Bonour) with protocol independent developer code

Enable variety of protocols (e.g. UPnP, Bonour) with protocol independent developer code

Description:
Dear all,

As I told you before, I have an implementation of NSD for UPnP and
Bonjour, with extensions for exposing a service and communicating
between webapp and service.
Note: In Bonjour, exposing a service means providing a JSON service
description (à la SDCP), and sending messages means exchanging JSON
messages over plain text sockets.
By doing this, I have exactly the same level of functionality in UPnP
and Bonjour. And thus, my first service developer's first strong request
was "please get rid of anything protocol specific".
He wanted to specify a service type (whether in a search or in an
advertizing request) in a way that can be transparently implemented in
UPnP or Bonjour, depending on what is implemented. This assumes that
some implementations will have UPnP and Bonjour, and others will have
only one of the two, and he wants the same webapp to simply address all
cases.

I tried to implement this by specifying only the main COMMONFRAGMENT of
a service type.
In UPnP, a service type is "upnp:urn:DOMAIN:service:COMMONFRAGMENT:1"
(note: I chose my project name for DOMAIN)
In Bonjour, a service type is "zeroconf:_COMMONFRAGMENT._tcp.local."

I first attempted to implement the search for COMMONFRAGMENT on top of
my NSD implementation.
It was not possible. I had to modify/extend the NSD implementation.

By doing this, I do not remove the difference of NSD response between
UPnP and Bonjour, but the author's code can then be made
protocol-independent.
And I think that is a "good thing".

So I propose to allow, as first argument of getNetworkServices, a plain
string that is neither starting with "upnp:" nor "zeroconf:", in which
case, the service type matching would not be done as exact string
comparison, but by testing the inclusion of the first argument value in
the service type of discovered services.
If the absence of a prefix is a problem to anyone, using a prefix of
"fragment:" would also work.

What do you think ?
Best regards
JC
