038d3635de Low: tests: rework bulk event msg ipc test 
Some environments have very small dgram msg queues. In
these environments we have to be able to read off the event
queue before being able to send the rest of events for the
bulk event test.

95e48fdb76 Fix: ipcs: Properly disconnect client connection on POLLNVAL or any other error causing connection removal from mainloop. 
qb_ipcs_dispatch_connection_request is a callback function registered with
mainloop, or whatever other looping thread implementation is in use.  When
this callback is registered, a reference of the connection object is given
to the mainloop thread.  If this callback ever returns something none zero
the callback (and corresponding fd) is unregistered from the loop automatically,
so we must decrement the reference in this instance.

Since unregistering this callback from mainloop guarantees a disconnect
simply because requests on the fd are no longer processed, it is best
that we completely disconnect the connection (which will handle the unref)
when this callback returns an error... Otherwise since the fd is unregistered
from the mainloop thread, it may not be possible to detect a disconnect
in the future.

9b3be0b450 ringbuffer: use atomic ops on ringbuffer chunk magic 
The ringbuffer protocol uses the chunk magic number to indicate to the
other side what state a chunk is in.  It's therefore important to use
strongly ordered memory writes to make sure that neither the compiler
nor the CPU change the apparent order of the writes, since that would
result in corrupted messages.

f54764e1ec IPC: make each connection ref the owning service 
This is because the connection functions use the c->service pointer
and this needs to be mirrored in the reference counting.

The service can only be free'd when all connections are destroyed
and the user as unreferenced all previously referenced connections
and the service.

Fixes #62
