jmmv 486bbb836e Initial import of gstreamer0.10, version 0.10.1. This is an update of
gstreamer0.8 to the 0.10 series.  Changes:

Changes since 0.10.0:

      * element factory leak fixes
      * tests cleanup
      * BaseSrc seeking in other format than BYTES
      * collectpad fixes

Bugs fixed since 0.10.0:

      * 322441 : getcontext() in common/m4/gst-mcsc.m4 uses incorrect stac...
      * 323041 : [BASESRC] basesrc does not handle a seek to non-bytes for...
      * 323870 : [tools] gst-feedback needs updating for 0.9/0.10
      * 323882 : gst-launch manpage needs updates
      * 323905 : use return val of g_list_append

API added since 0.10.0:

      * GST_TYPE_STATIC_CAPS
      * GST_TYPE_STATIC_PAD_TEMPLATE
      * GstNetTimeProvider::active
      * gst_base_src_set_format

Changes from the 0.8 series to 0.10 series:

      * Refcounting and API revised for thread safety, see rules in
        docs/design/part-MT-refcounting.txt

      * Scheduling is now done by the elements, they start/stop
        processing threads themselves. This removes the need for
        a separate scheduler.

      * State changes now happen from sink to source. This makes sure
        that downstream elements are ready to process data when upstream
        starts producing.

      * EOS/ERROR/... does not change the state of elements anymore. This
        means that when the application sets the state on an element, it
        remains in this state.

      * GMainLoop integration. Information on the state of the pipeline
        is now received in the mainloop via the GstBus.

      * Events move separate from the datastream, this allows for both
        in and out of sync delivery of events.

      * Generic _pull() replaced by _pull_region() so that random access
        can be made faster.

      * data passing happens from PAUSED, called the preroll phase. In this
        state no data is rendered but it is queued in the sinks.

      * negotiation simplified. Caps are now attached to buffers and travel
        along with the datastream.

      * GstBuffer is now subclassable.

      * Ghostpads now look and feel like real pads.

      * New Seeking/flushing policy.

      * Addition of base classes and helper functions in the core to abstract
        away the harder parts of plugin development.

GStreamer is a library that allows the construction of graphs of
media-handling components, ranging from simple Ogg/Vorbis playback to
complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter technology
transparently. Developers can add new codecs and filters by writing a
simple plugin with a clean, generic interface.
GStreamer is released under the LGPL.
