4f004eff38 pad: rename GstActivateMode to GstPadActivateMode 
These might be useful:
sed -i -e 's/GstActivateMode/GstPadActivateMode/g' `git grep GstActivateMode | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GST_ACTIVATE_/GST_PAD_ACTIVATE_/g'    `git grep GST_ACTIVATE_   | sed -e 's/:.*//' | sort -u`

168e5c0abb basetransform: cache transformed caps where appropriate 
Speeds up negotiation a fair bit on a contrived pipeline

01172b8126 basetransform: send delayed events earlier 
Some elements (such as videorate) might push buffers early,
for instance in in transform_ip. We want events (and in particular
any NEWSEGMENT event) to be pushed before that.

This fixes transmageddon wedging on converting a file starting
with a non zero offset to Ogg.

bdbc069348 Rework GstSegment handling 
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.

e7bf5484c7 base: Fix pad callbacks so they handle when parent goes away 
1) We need to lock and get a strong ref to the parent, if still there.
2) If it has gone away, we need to handle that gracefully.

This is necessary in order to safely modify a running pipeline. Has been
observed when a streaming thread is doing a buffer_alloc() while an
application thread sends an event on a pad further downstream, and from
within a pad probe (holding STREAM_LOCK) carries out the pipeline plumbing
