h2645parser: Catch overflows in AVC/HEVC NAL unit length calculations
...
Offset and size are stored as 32 bit guint and might overflow when
adding the nal_length_size, so let's avoid that.
For the size this would happen if the AVC/HEVC NAL unit size happens to
be stored in 4 bytes and is 4294967292 or higher, which is likely
corrupted data anyway.
For the offset this is something for the caller of these functions to
take care of but is unlikely to happen as it would require parsing on a
>4GB buffer.
Allowing these overflows causes all kinds of follow-up bugs in the
h2645parse elements, ranging from infinite loops and memory leaks to
potential memory corruptions.

h265parse: recognize more HEVC extension streams
...
There are streams which have the right general_profile_idc and
general_profile_compatibility_flag, but don't have the right extension
flags. We may try to use chroma_format_idc and bit_depth to
recognize these streams.

h265parser: select the right profile for high throughput SCC stream
...
Currently screen-extended-high-throughput-444 is recognized as
screen-extended-main-444, screen-extended-high-throughput-444-10 is
recognized as screen-extended-main-444-10 because they have the same
extension flags, so without this patch, it is possible that a decoder
which supports SCC but doesn't support throughput SCC will try to decode
a throughput SCC stream.

Add an API to create raw SEI nal unit. This would be useful in case
an user want to create SEI nal data and inject the SEI nal data

h265parser: decouple GstH265Profile and GstH265ProfileIDC
...
We used to have the same enum to represent H265 profiles and idc values.
Those are no longer the same with extension profiles defined from
version 2 of the spec.
Split those enums so the semantic of each is clearer and we'll be able
to add extension profiles to GstH265Profile.
Also add gst_h265_profile_tier_level_get_profile() to retrieve the
GstH265Profile from the GstH265ProfileTierLevel. It will be used to
implement the detection of extension profiles.
