Registry rewrite.  Changes registry from being a file created
by a tool into a simple cache file created automatically by
libgstreamer.  Removed gst-register (because it's no longer
needed).  Remove registry pools, because we only have one
registry implementation (XML).  Fix up other subsystems as
necessary.

/*
* Design:
*
* The GstRegistry object is a list of plugins and some functions
* for dealing with them. Plugins are matched 1-1 with a file on
* disk, and may or may not be loaded at a given time. There may
* be multiple GstRegistry objects, but the "default registry" is
* the only object that has any meaning to the core.
*
* The registry.xml file in 0.9 is actually a cache of plugin
* information. This is unlike previous versions, where the registry
* file was the primary source of plugin information, and was created
* by the gst-register command.
*
* In 0.9, the primary source, at all times, of plugin information
* is each plugin file itself. Thus, if an application wants
* information about a particular plugin, or wants to search for
* a feature that satisfies given criteria, the primary means of
* doing so is to load every plugin and look at the resulting
* information that is gathered in the default registry. Clearly,
* this is a time consuming process, so we cache information in
* the registry.xml file.
*
* On startup, plugins are searched for in the plugin search path.
* This path can be set directly using the GST_PLUGIN_PATH
* environment variable. The registry file is loaded from
* ~/.gstreamer-0.9/registry.xml or the file listed in the
* GST_REGISTRY env var. The only reason to change the registry
* location is for testing.
*
* For each plugin that is found in the plugin search path, there
* could be 3 possibilities for cached information:
* - the cache may not contain information about a given file.
* - the cache may have stale information.
* - the cache may have current information.
* In the first two cases, the plugin is loaded and the cache
* updated. In addition to these cases, the cache may have entries
* for plugins that are not relevant to the current process. These
* are marked as not available to the current process. If the
* cache is updated for whatever reason, it is marked dirty.
*
* A dirty cache is written out at the end of initialization. Each
* entry is checked to make sure the information is minimally valid.
* If not, the entry is simply dropped.
*
* Implementation notes:
*
* The "cache" and "default registry" are different concepts and
* can represent different sets of plugins. For various reasons,
* at init time, the cache is stored in the default registry, and
* plugins not relevant to the current process are marked with the
* GST_PLUGIN_FLAG_CACHED bit. These plugins are removed at the
* end of intitialization.
