upstart support
Patch dh_installinit to handle upstart job files in preference over init scripts, and provide compatibility symlinks in /etc/init.d for sysv-rc implementations. Closes: #536035.

=head1 DESCRIPTION
dh_installinit is a debhelper program that is responsible for installing
-init scripts and associated defaults files into package build directories.
+upstart job files or init scripts with associated defaults files into package
+build directories, and in the former case providing compatibility handling
+for non-upstart systems.
It also automatically generates the postinst and postrm and prerm commands
needed to set up the symlinks in /etc/rc*.d/ and to start and stop the init
scripts.
-If a file named debian/package.init exists, then it is installed into
-etc/init.d/package in the package build directory, with "package" replaced
+If a file named debian/package.upstart exists, then it is installed into
+etc/init/package.conf in the package build directory, with "package" replaced
by the package name.
+Otherwise, if a file named debian/package.init exists, then it is installed
+into etc/init.d/package in the package build directory, with "package"
+replaced by the package name.
+
If a file named debian/package.default exists, then it is installed into
etc/default/package in the package build directory, with "package" replaced
by the package name.
