The element should allocate GstFdMemory large enough to fit incoming
memory's size plus its potential offset.
Fixes "gst_memory_resize: assertion 'size + mem->offset + offset <=
mem->maxsize' failed".
Fixes an issue reproducible on Raspberry Pi 4 that results in a garbled
image on the receiver's end:
gst-launch-1.0 libcamerasrc ! unixfdsink socket-path=/tmp/socket
gst-launch-1.0 unixfdsrc socket-path=/tmp/socket ! autovideosink

Serialize every GstMeta that supports serialization into the NEW_BUFFER
payload. This is especially important for GstVideoMeta in the case of
multiplanar buffers, or if stride!=width.

This pair of elements, inspired from shmsink/shmsrc, send unix file
descriptors (e.g. memfd, dmabuf) from one sink to multiple source
elements in other processes.
The unixfdsink proposes a memfd/shm allocator, which causes for example
videotestsrc to write directly into memories that can be transfered to
other processes without copying.
