In handle_connect_tx_command() and handle_disconnect_tx_command(),
AVB_PACKET_ACMP_SET_MESSAGE_TYPE() is called after the goto done
target. When find_stream() fails and jumps to done, the response
is sent with the original command message type (e.g., CONNECT_TX_COMMAND)
instead of the correct response type (CONNECT_TX_RESPONSE).
Move the SET_MESSAGE_TYPE call before find_stream() so error responses
are always sent with the correct response message type.

AVB_MRP_SEND_NEW was defined as 0, making it indistinguishable from
"no pending send" in the MSRP and MVRP event handlers which check
`if (!pending_send)`. This meant that when an attribute was first
declared (applicant state VN or AN), the NEW message was silently
dropped instead of being transmitted on the network.
Fix by shifting all AVB_MRP_SEND_* values to start at 1, so that 0
unambiguously means "no send pending". Update the MSRP and MVRP
encoders to subtract 1 when encoding to the IEEE 802.1Q wire format
(which uses 0-based event values).

The msrp_notify() and mvrp_notify() functions call dispatch table
notify callbacks without checking for NULL. In MSRP, the
TALKER_FAILED attribute type has a NULL notify callback, which would
crash if a talker-failed attribute received a registrar state change
notification (e.g. RX_NEW triggering NOTIFY_NEW).
Add NULL checks before calling the dispatch notify callbacks, matching
the defensive pattern used in the encode path.

server_add_descriptor() allocates the descriptor and its data in a
single calloc (d->ptr = SPA_PTROFF(d, sizeof(struct descriptor))),
so d->ptr points inside the same allocation as d. Calling free(d->ptr)
frees an interior pointer, corrupting the heap. Only free(d) is needed.

In the current state the GET/SET stream format can handle the commands
response however, yet, it does not take care of checking that:
* A bound input stream cannot have it set, should reply accordingly
* A STREAMING_STREAM output stream cannot have it set, should reply
accordingly.
