Support for (nullable) was added to G-I at the same time as nullable
return values. Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

Compliments my previous patch for gst_caps_set_features, which would
previously assert and leak the old GstCapsFeatures if the caps already
had a GstCapsFeatures and you were trying to replace it with a new one.
When the parser receives non-aligned packets it can push a buffer
and get a not-linked return while still leaving some data still to
be parsed. This remaining data will not form a complete frame and
the subclass likely returns _OK and baseparse would take that
as the return, while it the element is actually not-linked.
This patch fixes this by storing the last flow-return from a push
and using that if a parsing operation doesn't result in data being
flushed or skipped.

Boxed types can't be derived from, and we don't support
deriving from our special fundamental types (the code
checks for GType equality in most places.
When no data is coming from sinkpads and eos events
arrived at one of the sinkpad, funnel forwards the EOS
event to downstream. It forwards the EOS because lastsink pad
is NULL. Also the unit testcase of the funnel is not checking
the correct behavior as it should. The unit test case should
fail if one of the sink pad has already EOS present on it and
we are trying to push one more EOS.

Currently we leak the internal representation of them as two GValues that
contain a fraction. Without this we could store fraction ranges as
data[0] = (min_n << 32) | (min_d)
data[1] = (max_n << 32) | (max_d)
and wouldn't require an additional allocation per range.
Otherwise negative values will sets all of the 64 bits due to two's
complement's definition of negative values.
Also add a test for negative int ranges.
Both gst_value_intersect and gst_value_subtract will call
gst_value_compare if one of their arguments isn't a list.
gst_value_compare will then re-do a check to see if one of
the arguments is a list (for the special case of comparing a unitary
value with a list of length 1).
The problem is that the various G_VALUE_HOLDS represent an expensive
amount of calling gst_value_compare (almost half of it) to see if
the provided arguments are list. These checks can be done without
when we know that the arguments aren't lists.
* Create a new "nolist" gst_value_compare which avoids that special
case comparision
Benchmarks:
valgrind/callgrind: average speedup in instruction calls for
gst_value_intersect and gst_value_subtract is around 56% (Makes 63%
of the calls it used to take previously)
tests/benchmarks/capsnego: With default settings (depth 4, children 3
607 elements), time taken for transition from READY to PAUSED:
Before : 00.391519153
After : 00.220397492
56% of the time previously used, +77% speedup
