d3251968d1 Prepare to rename RTC_NOTREACHED to RTC_DCHECK_NOTREACHED
Add implementation of RTC_DCHECK_NOTREACHED equal to the RTC_NOTREACHED.
The new macros will replace the old one when old one's usage will be
removed. The idea of the renaming to provide a clear signal that this
is debug build only macros and will be stripped in the production build.

7f876c8930 Allow full SVC to reference T0 frame only after it has been encoded
The VP9 encoder may drop a frame internally which will not advance the
frame pattern. Consider the following scenario where only spatial layer
0 and temporal layer 0 is active:

1. Key frame encoded
2. Spatial layer 1 is activated
3. Delta T0 dropped
4. Delta T0 encoded

No S1T0 frame is encoded in (1) since it's not active. When
NextFrameConfig is called in (3) it will say that future frames may
reference T0 on both S0 and S1, but it's then dropped.

On step (4), the SVC controller essentially thinks it's encoding a new
picture and will happily reference the T0 on what it thinks is the first
delta frame. However, this is actually still the key frame and since
there was no S1T0 frame produced it will reference an invalid buffer.

To fix this, only say it's possible to reference a T0 frame after it has
been successfully encoded.

f91f8b517a Consolidate full svc structures in one source file
Keeping structures in the same file makes it clearer which are missing
and makes it easier to see if structures are consistent with one another.

ba91dbcb3e In SVC controllers add support for frames dropped by encoder
by updating flag that T1 frame can be referenced when it is encoded
rather than when it is sent for encoding.
Otherwise when encoder drops T1 frame, configuration for following T2 frame would
still try to reference that absent T1 frame leading to invalid references.
