[Pkg-nginx-maintainers] Bug#844473: Update nginx module nchan to 1.0.6

[nobody]

The latest version of Nchan is now 1.0.8. I've updated the debian build,
you can pull it from https://github.com/slact/nginx-deb

Changes since 1.0.6:

1.0.8 (Nov. 28 2016)
 fix: possible crash under severely heavy load, introduced in 1.0.7 with
stack-overflow fix
1.0.7 (Nov. 27 2016)
 fix: memory leak after websocket publisher uncleanly aborts connection
 fix: misbehaving websocket publisher with nchan_publisher_upstream_request
 fix: potential stack overflow with very large message buffers
 fix: invalid memory access with empty nchan_publisher_upstream_request
for websocket publisher
 fix: incorrect handling of chunked response from
nchan_publisher_upstream_request
 fix: publishing through websocket too fast may result in buffered
messages that never arrive
 fix: DELETE to multiplexed channel should delete all listed channels
 fix: abort if publishing to multiple channels while using redis
