* 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
This was initially copied from glib. How ever I have
simplified it to only support proper atomic operations
with gcc builtin __sync calls. The backup is pthread_spin_lock().
I have also obviously namespaced the code to qb_.
