    fix: dev: Fix the UDP receive buffer size for libuv recvmmsg

    libuv splits the UDP receive buffer into UV__UDP_DGRAM_MAXSIZE
    (64 * 1024) byte chunks, so a buffer of 20 * UINT16_MAX bytes only
    holds 19 chunks and the last datagram slot of every recvmmsg call went
    unused.  Size the buffer as 20 * 64 KiB so that all 20 slots are
    usable.

    Merge branch 'ondrej/fix-libuv-recvbuf' into 'main'
