Revert "Parallelize depend file generation"
This reverts commit d5b6ec450f.
parallel depend ddc does not significantly speed up compilation,
intermediately generated .ddc files can cause problems if compilation is interrupted unexpectedly

According to rfc1112, section 7.2:
"An ICMP error message (Destination Unreachable, Time Exceeded, Parameter Problem, Source Quench, or Redirect) is
never generated in response to a datagram destined to an IP host group."

when tcp socket stays in TCP_FIN_WAIT_1 or TCP_FIN_WAIT_2,not actively calling tcp_close_eventhandler,can reuslt in some TCP socket being set to a closed state,but nofosegs are not directly released,leading to IOB resource leakage.

If the device's CPU resources are scarce and unable to execute the
ip_fragin_timerwork callback in a timely manner, this assert will
be triggered. This is a normal scenario that can occur. The logic
should be modified to wait for the ip_fragin_timerwork to be
executed if it has not been executed yet.

1. Tcp will idle loop by tcp_timer when have no packet to send. This will cause low-power devices to be frequently woken up.
2. We should add tcp_timer when timer has been canceled and have packet to send.

For udp localsocket current implementation,the sent information only carries the packet info.
The receiver receives the information,it don't know who the information comes from.
Thus the receiver doesn't know who to send the response message to.
We add sender's binding path info in the information,the receiver knows who sent the information
based on the parsed information.
The receiver knows who to send the response message to.

below command to create mbim NIC on host

NuttX's MBIM device implementation adds an additional MBIM network
card to the NuttX system, which can debug the data communication with
the host, but this network card is unnecessary and needs to be removed
when the business actually uses this driver, And the cdcncm_receive
method needs to be re-implemented.

The Bluetooth network on N62 does not retransmit packet, so no packet
retransmition if we drop one, we will drop packet when tcp_close_eventhandler
is register and invoke by tcp_input. then we will always early return and
never stop, the peer will only close the connection if we send reset packet.
precondition:
close -> register tcp_close_eventhandler;
tcp_input -> tcp_callback(TCP_NEWDATA) -> devif_conn_event -> tcp_close_eventhandler
-> flags &= ~TCP_NEWDATA -> NOT entry tcp_data_event -> conn->recvreq NOT increase
old flow:
tcp_input -> tcp->seqno greater than conn->rcvseq -> tcp_send(TCP_ACK)
with this patch:
tcp_input -> tcp->seqno greater than conn->rcvseq -> !TCP_ESTABLISHED
-> case TCP_FIN_WAIT_1 -> dev->d_len greater than 0 -> tcp_reset
