The patch allows for running 0MQ on Solaris and HP-UX
even though ulimit for max number of file descriptors
is set to unlimited.

The problem was that RLIMIT_NOFILE can be set to RLIM_INIFINITY
(and that appears to be default on AIX) which caused 0MQ to fail.

The meat of the patch was contributed by Douglas Creager.

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.

So far these were declared as C++ static functions which
was incorrect and caused warnings with SunStudio.

On systems using GCC 4.0 or newer which support symbol visibility in shared
libraries, use -fvisibility=hidden and only export explict API functions
defined in zmq.cpp. We do not enable -fvisibility on MinGW since this uses a
separate mechanism (__declspec).

HP's version of STL doesn't allow for initialisation of basic_string
(blob_t) using NULL pointer, while SGI's implementation is OK with
that. Fixed.

- RAND_bytes function resides in crypto library
- pollfd on AIX used 'reqevents' instead of events and 'retnevents'
instead of 'revents'

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.

For historical reasons queue to transfer commands between
threads was called 'signaler'. Given that it was used to
pass commands rather than signals it was renamed to 'mailbox',
see Erlang mailboxes.

Threads were so far identified by integers called 'slots'.
This patch renames them to more comprehensible 'tid's (thread IDs).

If the socketpair used by signaler_t fills up, this can lead to deadlock.
This patch provides partial resolution by attempting to resize SO_SNDBUF on
the writer side, and if that fails we shall at least assert rather than
hang.
I've also refactored the signaler_t code to make the platform-dependent
parts clearer and have tested both the MSG_DONTWAIT and standard POSIX path
in recv.
The Win32 implementation currently does not implement resizing as I'm not
convinced that it's safe, but it will also assert like other platforms if
signaler_t::send() cannot succeed.
The OpenVMS implementation has been carried forward but is untested.
