Solution: add it. Some of the work that I do happens during working
hours and hence the copyright belongs to my employer, Brocade
Communications Systems Inc. Note this in the AUTHORS file.

Problem: pkgconfig file does not support static link

Solution: add dependencies, if necessary, to the .private Libs and
Requires field of the pkgconfig file at build time.
This way pkg-config --static --libs libzmq will correctly print
dependencies if they were used to build the static libzmq.a library.

pass through poller events

instead of allocating a new, identical array and copying the data.

This is only safe while zmq_poller_event_t and zmq::socket_poller_t::event_t are the same struct,
which they presumably will remain.

add n_events argument to zmq_poller_wait_all

avoids unnecessary heap allocations, races on the number of items

Problem: zmq_poller only signals one event

Solution: zmq_poller_wait_all signals all events

allows signaling multiple events with one call to zmq_poller_wait_all
rather than emitting only one event.

this prepares for zmq_poll being based on zmq_poller,
which requires events for all sockets rather than just one.

* fix bugs of the pollset

1. extend 'fd_table' when fd_ is greater or equal than the size of 'fd_table';
2. delete specific fd from pollset before reset pollin or pollout according the description of AIX document

* fix bugs of the pollset

edit error. remove extra spaces and paste fault

* fix bugs of pollset

remove character '-' at the end line.

fix markup syntax on zmq_tipc(7) page

Fix fd_entry may reference invalid object.

fd_entries (std::vector) can reallocate underlying storage
which will render reference invalid.

Problem: zmq_ctx_term asserts with connect-before-bind and sockets with identity over inproc transport

Solution: add a zmq_assert to check if the ephemeral sockets created
to drain the queue of pending inproc connecting sockets was allocated
successfully.

Problem: zmq_ctx_term asserts with connect-before-bind and sockets with identity over inproc transport

Solution: check if the connecting inproc socket has been closed
before trying to send the identity.
Otherwise the pipe will be in waiting_for_delimiter state causing
writes to fail and the connect to assert when the context is being
torn down and the pending inproc connects are resolved.
Add test case that covers this behaviour.

Solution: add one to increase coverage

Problem: Pub socket crashes on client disconnect. 

Problem: Pub socket crashes on client disconnect.  family_entry.fd_entries [i] is modified in zmq::select_t::rm_fd()
Solution: do not copy family_entry.fd_entries [i]

Problem: documentation markup unrecognized

The effect can be seen on http://api.zeromq.org/4-2:zmq-getsockopt at
options ZMQ_USE_FD and ZMQ_RATE.

Solution: fix length of squiggly line under option title

Pollset-change the position of `pollset`

remove pollset.hpp/.cpp to src directory

Pollset

add a new poller named pollset which will get benefit of performance in AIX platform.

Problem: zmq_connect with IPv6 "source:port;dest:port" format is broken

Solution: allow for '[' character when doing the basic sanity check
on the TCP endpoint.
Also add unit tests for both IPv4 and IPv6 source;dest format.

Solution: add them

Solution: add a test for this use case

Solution: add disconnect and unbind calls to the test

Solution: refactor it to allow for multiple functionalities to be
tested
