To allow the refcounting tracer to work better. In childproxy/iterator
these might be plain GObjects but gst_object_unref() also works on them.
In other places where it is never GstObject, g_object_unref() is kept.
The real use case is when downstream didn't set a pool or
allocation params, in which case we expect the tee to not
create a pool or param from thin air. Dowstream setting
an pool with size=0 was in fact testing a downstream element
bug. The fact we handle that is accidental.
If the aggregated size is 0 and we create a pool, the pool would provide
buffers with no memory assigned. Handle that case and skip the pool.
This was the behaviour before cf803ea9f4.
Add a test for this scenario.

In the unit test refactoring, the unlinked pad required to test
the different behaviour induced by "allow-not-linked" property
was removed.
Commit e364d7944e
Move all the code for this test in the proper function, and re-add
the missing unlinked pad. This makes the test useful again.
Split the large allocation_query test into seperate tests. Add a setup helper
to reduce code duplication. Fix the original test that used fail_unless instead
of ck_assert_int_eq and had it accidentially working.
This property avoids not linked error when all the pads are unlinked
or when there are no source pads. This is useful in dynamic pipelines
where it can happen that for a short time there are no pads at all or
all downstream pads are not linked yet.

This reverts commit 9ef1346b1f.
Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.
Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Original commit message from CVS:
* plugins/elements/gsttee.c: (gst_tee_handle_buffer):
Fix flow aggregation of tee. Error out immediately for all flow returns
except OK and NOT_LINKED, return NOT_LINKED if all pads are not linked
and return OK if at least one pad is linked.
Before we errored out on "fatal" flow returns (i.e. not for WRONG_STATE)
and otherwise returned the flow return of the last pad, which is wrong.
* tests/check/elements/tee.c: (_fake_chain), (_fake_chain_error),
(GST_START_TEST), (tee_suite):
Add unit tests for the flow aggregation.

Make the tee stress-test a little less stressful so it doesn't just
time out on slow-machines, and remove a small race when it's starting

Be a lot smarter when deciding what srcpad to use for proxying

Keep track of what pads we already pushed on in case we have pads
