Fixes not receiving unsubscription messages in XPUB socket with
ZMQ_XPUB_VERBOSE and using a XSUB-XPUB proxy in front.
This adds two modifications:
- It adds a new flag, ZMQ_XPUB_VERBOSE_UNSUBSCRIBE, to enable verbose
unsubscription messages, necessary when using a XSUB/XPUB proxy.
- It adds a boolean switch to zmq::mtrie_t::rm () to control if the
callback is invoked every time or only in the last removal. Necessary
when a pipe is terminated and the verbose mode for unsubscriptions is
enabled.
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.
Solution: specify these grants in the header of each source file.
Copyrights had become ads for Sustrik's corporate sponsors, going against the original
agreement to share copyrights with the community (that agreement was: one line stating
iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads
is also unfair to the many individual authors. I've removed ALL corporate title from
the source files so the copyright statements can now be centralized in AUTHORS and
source files can be properly updated on an annual basis.
When there were both '0' and '255' subnodes in (mtrie)
the removal of the node resulted in an infinite loop.
Fixed.

Aside of fixing couple of corner cases this patch turns the 'match'
function in mtrie from recursive to iterative.
