Squashed 'external/toxcore/c-toxcore/' changes from 465fbc8721..1701691d53

1701691d53 chore(toxav): use realtime deadline for vp8 encoder Technically all this does is choose a quality based on frame duration, which we always set to 1, and as such is always realtime. (In same timebase as pts, which we use as a frame counter...)
a875058675 fix(toxav): remove extra copy of video frame on encode Tested and works, but there might be alignment issues and other stuff.
6794447518 chore(toxav): increase the idle iterate interval to 1 second and remove a non-existant reference in a comment
3e22fd5cc4 fix(toxav): handle vpx_image_alloc failure
4057695c5f chore(toxav): tighten the video bitrate to the same as the vp8 encoder internally checks.
3e6b22f5de chore: Release v0.2.21
219773bff5 fix(ngc): dont double every message, if we are not directly connected but we and the other peer would support direct.

+## v0.2.21 (2025-05-15)
+
+### Release notes
+
+This release brings 2 great featues. First, the abillty to disable DNS lookups, which has been a long requested security feature, which we plan to default to in an upcoming version.
+Second, there is an network profiler, which tallies up sent and received network packets.
+
+Beside these features we also have fixes like a 75% memory usage reduction for NGCs and connecting to NGC with a password if we are already joined, which might be necessary if a password was set or changed while you where away.
+Furthermore, we now have better localhost discovery, which means that nodes on the same system find each other.
+
+---
+
+If you have not yet upgraded to the previous release (0.2.20), you absolutely should, as it fixes a security issue. All releases before 0.2.20 used VBR opus encoding, which is susceptible to transcription attacks. ( see https://github.com/TokTok/c-toxcore/pull/2757 )
