073f927801 Low: log: return filter type enum to preserve abi compatibilty with corosync 
This returns abi compatiblity with libqb v0.16.0. There was a subtle
change in behavior caused by reordering the log filter enum in
v0.17.0.

2a06ffecde epoll: don't miss poll events under high load 
If multiple epoll sources generate events simultaneously, it is possible
for more jobs to be added to particular priority level than will be
handled in one go by qb_loop_run_level(). If one of these epoll sources
gains a new event (say, by switching from "readable" to "readable and
writeable"), then this new event would be missed.

To fix this, merge new epoll events into revents regardless of whether
the job is on the joblist. When the job is dispatched, revents will be
cleared, or the epoll source will be deleted entirely.

0cdda23d1e ipc_shm: fix error handling in qb_ipcs_shm_connect() 
The request and response SHM segments were being closed under the wrong
labels, and the event SHM segment wasn't being cleaned up at all.

fad9ce01a0 ringbuffer: fix size in qb_rb_create_from_file() 
qb_rb_open() expects the size field to represent the maximum chunk size.
It adds QB_RB_CHUNK_MARGIN + 1 and rounds up to the page size to
determine the ringbuffer's total size. When creating a ringbuffer from a
file we must compensate by subtracting this amount from the file's size.

edd2eec16c ringbuffer: fix qb_rb_open_2() debug format string 
qb_log_target_formats() does not support formatting size_t values with
%zd.  Use %ld to format them as long integers instead.

6a2ff420e1 High: ipcs: Prevent ipc server use after free. 
The ipc server registers the bind socket to
the poll loop in order to be alerted to new
connection requests. Upon shutdown, the ipc server
does not remove this poll entry. This patch fixes
this use after free.

58c0c90979 Low: ipc: Remove ipc connection reference given to dispatch functions 
We don't need to give the dispatch_add callback a reference
since the dispatch_del callback must occur before the
connection is destroyed. This extra reference counting
causes unnecessary complexity.

81ca7d30de ipc_setup: Set SO_PASSCRED on listener socket 
This is needed, because newer kernels doesn't correctly support setting
SO_PASSCRED on sockets returned by accept call, but socket option must
be set on server socket (before accept call).

75f7ed3737 Bump version to 0.16.0 ... do not use version 0.15.0 
The use of version-info conflicted with the naming
convention used to represent libqb version numbers. Because
of this the shared library file used for release 0.15.0
did not properly match the release version.  From now on
the version number will be manually set to guarantee consistency
between .so file and release version.
