Implements the SP wire protocol, and infrastructure for legacy wire
protocol support.
Also added an XS_SERVICE_ID socket option to set the service id and renamed
the XS_PROTOCOL option to XS_PATTERN_VERSION.
The following pattern versions are supported:
PAIR: v3
PUBSUB: v1 (legacy), v4
REQREP: v2
PIPELINE: v3
SURVEY: v2
Note that all existing pattern versions have been bumped by 1 to allow for
use of legacy protocols (otherwise there would be no way to distinguish
between e.g. PUBSUB v3 and PUBSUB v3 using SP).

Implements SP protocol versioning, legacy protocol support, and the
following pattern protocol versions:
PAIR: v2
PUBSUB: v1 (legacy), v3
REQREP: v1
PIPELINE: v2
SURVEY: v1
Engine support is only for stream_engine_t at this stage.

It can be used to timeout the survey. Value is in milliseconds
and -1 means infinite (default).

- subscription forwarding is handled by XSUB socket
- filtering is handled by SUB sockets
- subscriptions are decoupled from filter engines
- filter doesn't have to be able to enumarate the subscriptions
(no sf_enumerate function)

This patch introduces following features:
- XS_PLUGIN context option to add plugins to libxs
- XS_FILTER option to switch between different filter types
- Automatic loading of plug-ins is *not* implemented.
From the implementation point of view:
- standard prefix filter is implemented as a pluggable filter
- trie_t and mtrie_t are joined into a single class
- the code for 0MQ/3.1 compatibility is left in in the form of comments
- new test for testing re-subscriptions is added

However, the "durable socket" behaviour wasn't re-added.
Identities are used solely for routing in REQ/REP pattern.

The filtering is now done depending on the socket type. SUB socket
filters the messages (end-to-end filtering) while XSUB relies
on upstream nodes to do (imprefect) filtering.

So far the requests in req/rep pattern were delivered to and processed
by worker even though the original requester was dead. Thus,
the worker processing replies with noone to deliver results to.
This optimisation drops requests in two situations:
1. Queued inbound requests in XREP socket when peer disconnects.
2. Queued outbound requests in XREQ when socket is closed.

This option is a performance tweak. In devices XSUB socket filters
the messages just to send them to XPUB socket which filters them
once more. Setting ZMQ_FILTER option to 0 allows to switch the
filtering in XSUB socket off.

So far, there was a pair of unidirectional pipes between a socket
and a session (or an inproc peer). This resulted in complex
problems with half-closed states and tracking which inpipe
corresponds to which outpipe.
This patch doesn't add any functionality in itself, but is
essential for further work on features like subscription
forwarding.

On-disk storage should be implemented in devices rather than
in 0MQ core. 0MQ is a networking library and there's no point
in storing network buffers on disk.

Multicast loopback is not a real multicast, rather a kernel-space
simulation. Moreover, it tends to be rather unreliable and lossy.
Removing the option will force users to use transports better
suited for the job, such as inproc or ipc.

For very high-speed message systems, the memory used for recovery can get to
be very large. The corrent limitation on that reduction is the ZMQ_RECOVERY_IVL
of 1 sec. I added in an additional option ZMQ_RECOVERY_IVL_MSEC, which is the
Recovery Interval in milliseconds. If used, this will override the previous
one, and allow you to set a sub-second recovery interval. If not set, the
default behavior is to use ZMQ_RECOVERY_IVL.

1. ZMQ_LINGER option can be set/get
2. options are part of own_t base class rather than being declared
separately by individual objects
3. Linger option is propagated with "term" command so that the
newest value of it is used rather than the stored old one.
4. Session sets the linger timer if needed and terminates
as soon as it expires.
5. Corresponding documentation updated.

This commit introduces the necessary changes necessary
for implementing flow control. None of the socket types
implements the flow control yet. The code will crash when
the flow control is enabled and the thw lwm is reached.
The following commits will add flow-control support for
individual socket types.
