8463b4d55e SWAP functionality removed 
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.

f7123de943 Fix socket_t::recv() hang scenario where initial call to process_commands() eats signal 
Added block boolean var to second process_commands() invocation for blocking sockets
instead of always using true.  This prevents the process_commands() call from hanging
when a message is received with an empty queue after the call to xrecv() but
prior to the initial call to process_commands() invoked when ++ticks == inbound_poll_rate.

9da84a5239 signaler renamed to mailbox

0a03e86e95 ZMQ_LINGER socket option added. 
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.

05d908492d WIP: Socket migration between threads, new zmq_close() semantics 
Sockets may now be migrated between OS threads; sockets may not be used by
more than one thread at any time. To migrate a socket to another thread the
caller must ensure that a full memory barrier is called before using the
socket from the target thread.

The new zmq_close() semantics implement the behaviour discussed at:

http://lists.zeromq.org/pipermail/zeromq-dev/2010-July/004244.html

Specifically, zmq_close() is now deterministic and while it still returns
immediately, it does not discard any data that may still be queued for
sending. Further, zmq_term() will now block until all outstanding data has
been sent.

TODO: Many bugs have been introduced, needs testing. Further, SO_LINGER or
an equivalent mechanism (possibly a configurable timeout to zmq_term())
needs to be implemented.

61ee6fae53 Implement flow control 
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.
