Raja SubramanianandClaude Opus 5.5 9ddcc50767 sfu: parse VP8 and VP9 payload descriptors without an allocation (#4981) 
* sfu: parse VP8 and VP9 payload descriptors without an allocation

Replace ExtPacket.Payload with typed VP8 and VP9 pointer fields that point
at backing structs inside the ExtPacket, so parsing does not allocate and a
wrong codec type is a compile error.

Raja SubramanianandClaude Fable 5.1 bc849eb47d sfu/buffer: parse the dependency descriptor without allocating (#4953) 
* sfu/buffer: parse the dependency descriptor without allocating

Every VP9 and AV1 SVC packet allocated six objects in the dependency
descriptor parse: the descriptor, a clone of the frame template with
its three slices, a resolution copy, and a frame entity that took the
address of a parameter.

The pooled ExtDependencyDescriptor now owns the storage for the
descriptor, the template and the resolution, with fixed arrays for the
template's slices. The reader copies the matching template into that
storage.

Delta frame parse: 6 allocs, 176 B, 174 ns -> 0 allocs, 0 B, 122 ns.

* sfu/dd: never copy a parsed frame into a structure template

A caller can hand Unmarshal a descriptor whose FrameDependencies points
at one of the structure's templates. Copying the packet's custom fields
into it would change the template for every later packet, so the reader
allocates a fresh template in that case.

cnderrauberandboks1971 aeec75edeb H265 supoort and codec regression (#3358) 
* H265 supoort and codec regression

Support H265 codec.
Add optional codec regression for subscribers don't
support advanced codecs like H265, AV1, VP9.

* restart forwarder on upstream codec change

* tests

* Reneogitate new codec if client doesn't support change

* Add option to disable codec regression

A few more candidates to think about demoting
- Publisher mute changes
- Forwarder -> layer lock/upgrade/downgrade/overshoot adjusting
- StreamAllocator
