pulseaudio: conf-parser: add support for .d directories
Sato images should set allow-autospawn-for-root=true in /etc/pulse/client.conf, but in non-Sato images that option should be disabled by default. I first tried to have two packages that ship different versions of the client.conf file, but it turned out to be tricky to ensure that the package manager always chooses the package that provides the default version when the Sato package is not explicitly requested. This patch allows the Sato specific configuration to be installed in /etc/pulse/client.conf.d without replacing the default version of client.conf, which makes packaging much simpler.

+Subject: [PATCH] conf-parser: add support for .d directories
+
+This allows a configuration scheme where prior to loading
+configuration from "somefile", the parser first loads configuration
+from files in directory "somefile.d". This feature is currently
+enabled only for client.conf and daemon.conf.
+
+This makes it easier to create configuration packages in distributions
+when there's need to have different configuration in different setups.
+For example, the graphical Sato environment in OpenEmbedded-core needs
+to set allow-autospawn-for-root=true in client.conf, but the default
+configuration in OpenEmbedded-core should not set that option. With
+this patch, I can create a Sato-specific package that simply installs
+50-sato.conf in /etc/pulse/client.conf.d without conflicting with the
+main client.conf file coming from a different package.
+
+Upstream-Status: Submitted [http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/23592]
