Fixes #634397

The offset part of the granpos is not a sign of the newer encoding.
Use the version number instead.

This fixes the criticals thrown by theoraparse, and (at last) the
remaining part of #553244.

Observed a case where the sink went to null-state during the query,
hence the ringbuffer-pointer was NULL, causing a crash.

Moving the ringbuffer-check code until after the query, and hold the
lock during the check and while using the spec-values. It should not matter
to the query wether the ringbuffer is present or not, and it actually
gets a time bit more time to get the ringbuffer set up in this case!

Fixes #635231

Don't try to stream data on pads that are not added yet. This happens while we
discover the different streams.

Make sure that when _make_writable() returns a new buffer, we actually push that
one instead of the old one.

This will mainly allow Totem to know the language of those streams,
so the subtitle selection menu gets properly filled out.

This will allow switching from one stream to another without having to send
the headers for the new stream again.

allocate buffers using gst_buffer_new_and_alloc() instead of
gst_pad_alloc_buffer_and_set_caps(), as the first one will
cause the pad to block, and we don't want that since that will
prevent subsequent pads from being fed if a block occurs at
start, when all pads must be fed for playback to start.

This fixes autoplugging of the tiger element and other things.

Fixes a valgrind warning on jifmux tests on -bad caused by
unitialized bytes.

Fixes #637758

Don't call gst_bin_remove (bin, <invalid pointer>).

Add support for intercepting sink events in the depayloader by adding a new
vmethod.

Keep track of the timestamps even when we didn't generate decodable output.

When we have an invalid running-time (because we clipped, for example) use the
RTP base time for timestamping instead of generating wrong RTP timestamps.

Use set_segment_full to copy all segment values to the segment structure.

Previously it would only succeed to link if a new enough
libgstpbutils-0.10 was installed in the default library
search path.

with i686-apple-darwin10-gcc-4.2.1:

encoding-profile.h:134: warning: type qualifiers ignored on function return type
encoding-profile.c:240: warning: type qualifiers ignored on function return type
gstencodebin.c: In function 'next_unused_stream_profile':

gstencodebin.c:464: warning: format '%d' expects type 'int', but argument 8 has type 'GType'

Since we calculate timestamps by:

  timestamp = t0 + (out samples) / (out rate)

and durations by:

  duration = ((out samples) + (processed samples)) / (out rate) - timestamp

if t0 is nonzero, this would simplify to

  duration = t0 + (processed samples) / (out rate).

This duration is too large by the amount t0.  We should have done:

  duration = t0 + ((out samples) + (processed samples)) / (out rate) - timestamp

so that

  duration = (processed samples) / (out rate).

audioresample: changed num_gap_samples, num_nongap_samples from guint32 to guint64 so that gaps of greater than or equal to 2^32 samples do not cause integer overflow
