This patch is a preliminary work for mergine TCP and IPC connecters
and listeners. The ultimated goal is to avoid code duplication
occuring in these classes.

This patch provides a single place for selecting polling mechanisms
(polling.hpp). Up to now the selection was spread among the build
system and several source files.

Survey pattern is "multicast with reply". There are two roles:
surveyor and respondent. Surveyor publishes a survey which gets
delivered to all connected respondents. Each repondent can send
a response to the survey. All the responses are delivered to
the original surveyor. Once the surveyor decides that the survey
is over (e.g. deadline was reached) it can send initiate survey.
Late responses from old surveys are automatically discarded by
the surveyor socket.
Socket types: SURVEYOR, XSURVEYOR, RESPONDENT, XRESPONDENT
Patch also includes a test program with surveoyr, two respondents
and an intermediary device.

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

Moved xs_stopwatch_* functions from xs_utils.cpp/xs_utils.h, and
removed those files. This leaves us with a single header file for
libxs.

This simplifies the options for new users; either use libxs APIs or build
with --enable-libzmq and get libzmq 2.1 emulation.

Enabled using --enable-libzmq-compat, this installs a drop-in
libzmq library and headers. Not enabled by default since it will
overwrite any existing libzmq install.

The relationship of these two classes was 1:1.
Thus one of them was obsolete.

Poller object is virtualised. You can access poller via its
base class (poller_base_t) instead of using poller_t which
was a typedef pointing to actual derived class.

This is a preliminary patch allowing for socket-type-specific
functionality in the I/O thread. For example, message format
can be checked asynchronously and misbehaved connections dropped
straight away.

The engine was not used exclusively for TCP connections.
Rather it was used to handle any socket with SOCK_STREAM
semantics. The class was renamed to reflect its true function.

GENERIC allows to use 0MQ as a dumb networking framework.
It provides user with connect/disconnect notifications.
Also, each inbound message is labeled by ID of the connection
it originated from. Outbound messages should be labeled by
the ID of the connection to send them to.
To distinguish connect/disconnect notifications from common
messages, COMMAND flag was introduced.

Storing commands in OS socket buffers caused whole lot of
problems when free space in the buffer ran out. This patch
stores commands in ypipes instead and uses socketpair just
to signal the other thread, ie. at most one byte is stored
in the socketpair at any single instant.

This patch introduces two changes:
1. 32-bit ID is used to identify the peer instead of UUID
2. REQ socket seeds the label stack with unique 32-bit request ID
It also drops any replies with non-matching request ID

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.

Devices are basically applications on top of 0MQ stack. They
