The point of this example is to show how to set caps
on the source pad once it has been set on the sink pad.
So, in passthrough mode, the caps is just copied to the
source pad.

In one of the examples about gst_my_filter_setcaps() there is a variable
declared as "rate", but then the name "samplerate" is used when setting
the caps.
Use the name "rate" everywhere in gst_my_filter_setcaps().

alloc_buffer_and_set_caps.
* gst/gstpad.c (gst_pad_alloc_buffer): Changed to not call
set_caps on the source pad.
(gst_pad_alloc_buffer_and_set_caps): New function, does what
alloc_buffer used to do. Fixes#322874.

Add a chapter on caps negotiation, simplify the original code
samples a bit w.r.t. caps negotiation, add link to the advanced
section. Add a bunch of examples showing different use cases of
different types of caps negotiation. Upstream renegotiation isn't
fully documented yet since nobody knows how that works.
