ipc: add qb_ipcc_auth_get() API call (#418) 
* ipc: addd qb_ipcc_auth_get() API call

We can't use SO_PEERCRED on the client fd when using socket IPC
becayse it's a DGRAM socket (pacemaker tries this). So provide
an API to get the server credentials that libqb has already
squirreled away for its own purposes.

Also, fix some unused-variable compiler warnings in unix.c
when building on systems without posix_fallocate().

doxygen2man: Add option to read copyright line from the header file (#415) 
* doxygen2man: Add option to read copyright line from the header file

This should help make builds reproducible.

I tried various methods of getting the date, using 'git' is no use as
it could be run from a tarball, using the file date doesn't work either
so this seems a reasonable compromise.

* man: Use SOURCE_EPOCH to make manpage dates reproducible

Also add build-aux/update-copyright.sh to keep header file
copyright lines up-to-date.

All code taken from knet

8bd36d3e5c Feature: New api function to retrieve client buffer size 
When server side buffer limits are in use, this is
necessary to determine the buffer size the server
is enforcing after the client connection is established.

8a6b8d78db IPC: rewrite (simpler API & more structured layout). 
- implement using posix message queues
- implement using sys-v message queues
- implement shared memory ringbuffers
- add auth via unix sockets
- add items to the TODO

This is still a bit rough, more work to follow...
