Merge lp:~rainct/apt-zeroconf/cheetah into lp:apt-zeroconf

[Siegfried Gevatter]

[Siegfried Gevatter (rainct)]

 - Several fixes so that installing the package works correctly.
 - Fix http.py to look in the right path for the installed files.
 - Replace the manpage with a roff one, so that no conversion is needed.
 - Change hashbang to python2.6 so this works on Debian too (where 2.5 is default).
 - Merge in a couple other branches.
 - Other little changes to debian/.

[lp:~rainct/apt-zeroconf/cheetah]

142. By Siegfried Gevatter on 2010-02-01

Catch exception when socket is already in use and signalize this
condition with a special code.

143. By Siegfried Gevatter on 2010-02-01

apt-zeroconf.1: clarify the use of --daemon.

144. By Siegfried Gevatter on 2010-02-01

Fix debian/init.

The previous version was good enough for the package to work, but
"sudo service apt-zeroconf start/stop/restart" didn't work.

145. By Siegfried Gevatter on 2010-02-01

Some more changes here and there to make pep-8.py happy.
Change debian/init to always return 0 on stop, else dpkg-reconfigure gets mad.

146. By Siegfried Gevatter on 2010-02-01

azc_daemon/__init__.py: close all file descriptors after forking

Now that we don't use start-stop-daemon with the --background
workaround option anymore, dpkg-reconfigure was hanging again.
*Finally* I discovered the problem as being in _daemonize() :/.

147. By Siegfried Gevatter on 2010-02-01

Fix postinst, init file, etc. Installing the package works now!

140. By Siegfried Gevatter on 2010-01-31

Fix wrong path for HTML files when installed.

139. By Siegfried Gevatter on 2010-01-31

Remove now superfluous manpage generation code from setup.py.

138. By Siegfried Gevatter on 2010-01-31

Change python-central dependency to python-support.
