/**
* SECTION:gstpreset
* @short_description: helper interface for element presets
*
* This interface offers methods to query and manipulate parameter preset sets.
* A preset is a bunch of property settings, together with meta data and a name.
* The name of a preset serves as key for subsequent method calls to manipulate
* single presets.
* All instances of one type will share the list of presets. The list is created
* on demand, if presets are not used, the list is not created.
*
* The interface comes with a default implementation that serves most plugins.
* Wrapper plugins will override most methods to implement support for the
* native preset format of those wrapped plugins.
* One method that is useful to be overridden is gst_preset_get_property_names().
* With that one can control which properties are saved and in which order.
* When implementing support for read-only presets, one should set the vmethods
* for gst_preset_save_preset() and gst_preset_delete_preset() to %NULL.
* Applications can use gst_preset_is_editable() to check for that.
*
* The default implementation supports presets located in a system directory,
* application specific directory and in the users home directory. When getting
* a list of presets individual presets are read and overlaid in 1) system,
* 2) application and 3) user order. Whenever an earlier entry is newer, the
* later entries will be updated.

/* FIXME:
* - non racyness
* - we need to avoid two instances writing the preset file
* -> flock(fileno()), http://www.ecst.csuchico.edu/~beej/guide/ipc/flock.html
* -> open exclusive
* -> better save the new file to a tempfile and then rename?
* - we like to know when any other instance makes changes to the keyfile
* - then ui can be updated
* - and we make sure that we don't lose edits
* -> its the same problem actually, once for inside a process, once system-
* wide
* - can we use a lock inside a names shared memory segment?
*
* - should there be a 'preset-list' property to get the preset list
* (and to connect a notify:: to to listen for changes)
* we could use gnome_vfs_monitor_add() to monitor the user preset_file.
*
* - should there be a 'preset-name' property so that we can set a preset via
* gst-launch, or should we handle this with special syntax in gst-launch:
* gst-launch element preset:<preset-name> property=value ...
* - this would allow to have preset-bundles too (a preset on bins that
