sctp: do the basic send and recv for PLPMTUD probe
This patch does exactly what rfc8899#section-6.2.1.2 says:
The SCTP sender needs to be able to determine the total size of a probe packet. The HEARTBEAT chunk could carry a Heartbeat Information parameter that includes, besides the information suggested in [RFC4960], the probe size to help an implementation associate a HEARTBEAT ACK with the size of probe that was sent. The sender could also use other methods, such as sending a nonce and verifying the information returned also contains the corresponding nonce. The length of the PAD chunk is computed by reducing the probing size by the size of the SCTP common header and the HEARTBEAT chunk.
Note that HB ACK chunk will carry back whatever HB chunk carried, including the probe_size we put it in; We also check hbinfo->probe_size in the HB ACK against link->pl.probe_size to validate this HB ACK chunk.
v1->v2: - Remove the unused 'sp' and add static for sctp_packet_bundle_pad().

sctp: add the probe timer in transport for PLPMTUD
There are 3 timers described in rfc8899#section-5.1.1:
PROBE_TIMER, PMTU_RAISE_TIMER, CONFIRMATION_TIMER
This patches adds a 'probe_timer' in transport, and it works as either PROBE_TIMER or PMTU_RAISE_TIMER. At most time, it works as PROBE_TIMER and expires every a 'probe_interval' time to send the HB probe packet. When transport pl enters COMPLETE state, it works as PMTU_RAISE_TIMER and expires in 'probe_interval * 30' time to go back to SEARCH state and do searching again.
SCTP HB is an acknowledged packet, CONFIRMATION_TIMER is not needed.
The timer will start when transport pl enters BASE state and stop when it enters DISABLED state.

sctp: allow changing transport encap_port by peer packets
As rfc6951#section-5.4 says:
"After finding the SCTP association (which includes checking the verification tag), the UDP source port MUST be stored as the encapsulation port for the destination address the SCTP packet is received from (see Section 5.1).
When a non-encapsulated SCTP packet is received by the SCTP stack, the encapsulation of outgoing packets belonging to the same association and the corresponding destination address MUST be disabled."
transport encap_port should be updated by a validated incoming packet's udp src port.
We save the udp src port in sctp_input_cb->encap_port, and then update the transport in two places:
1. right after vtag is verified, which is required by RFC, and this allows the existent transports to be updated by the chunks that can only be processed on an asoc.
2. right before processing the 'init' where the transports are added, and this allows building a sctp over udp connection by client with the server not knowing the remote encap port.
3. when processing ootb_pkt and creating the temporary transport for the reply pkt.
Note that sctp_input_cb->header is removed, as it's not used any more in sctp.
v1->v2: - Change encap_port as __be16 for sctp_input_cb.

sctp: implement validate_data for sctp_stream_interleave
validate_data is added as a member of sctp_stream_interleave, used to validate ssn/chunk type for data or mid (message id)/chunk type for idata, called in sctp_eat_data.
If this check fails, an abort packet will be sent, as said in section 2.2.3 of RFC8260.
It also adds the process for idata in rx path. As Marcelo pointed out, there's no need to add event table for idata, but just share chunk_event_table with data's. It would drop data chunk for idata and drop idata chunk for data by calling validate_data in sctp_eat_data.
As last patch did, it also replaces sizeof(struct sctp_data_chunk) with sctp_datachk_len for rx path.
After this patch, the idata can be accepted and delivered to ulp layer.

sctp: implement assign_number for sctp_stream_interleave
assign_number is added as a member of sctp_stream_interleave, used to assign ssn for data or mid (message id) for idata, called in sctp_packet_append_data. sctp_chunk_assign_ssn is left as it is, and sctp_chunk_assign_mid is added for sctp_stream_interleave_1.
This procedure is described in section 2.2.2 of RFC8260.
All sizeof(struct sctp_data_chunk) in tx path is replaced with sctp_datachk_len, to make it right for idata as well. And also adjust sctp_chunk_is_data for SCTP_CID_I_DATA.
After this patch, idata can be built and sent in tx path.
Note that if sp strm_interleave is set, it has to wait_connect in sctp_sendmsg, as asoc intl_enable need to be known after 4 shake- hands, to decide if it should use data or idata later. data and idata can't be mixed to send in one asoc.

sctp: implement make_datafrag for sctp_stream_interleave
To avoid hundreds of checks for the different process on I-DATA chunk, struct sctp_stream_interleave is defined as a group of functions used to replace the codes in some place where it needs to do different job according to if the asoc intl_enabled is set.
With these ops, it only needs to initialize asoc->stream.si with sctp_stream_interleave_0 for normal data if asoc intl_enable is 0, or sctp_stream_interleave_1 for idata if asoc intl_enable is set in sctp_stream_init.
After that, the members in asoc->stream.si can be used directly in some special places without checking asoc intl_enable.
make_datafrag is the first member for sctp_stream_interleave, it's used to make data or idata frags, called in sctp_datamsg_from_user. The old function sctp_make_datafrag_empty needs to be adjust some to fit in this ops.
Note that as idata and data chunks have different length, it also defines data_chunk_len for sctp_stream_interleave to describe the chunk size.

These warnings were found by running 'make C=2 M=net/sctp/'.
They are introduced by not aware of Endian when coding stream reconf patches.
Since commit c0d8bab6ae51 ("sctp: add get and set sockopt for reconf_enable") enabled stream reconf feature for users, the Fixes tag below would use it.

sctp: fix some indents in sm_make_chunk.c
There are some bad indents of functions' defination in sm_make_chunk.c. They have been there since beginning, it was probably caused by that the typedef sctp_chunk_t was replaced with struct sctp_chunk.
So it's the best time to fix them in this patchset, it's also to fix some bad indents in other functions' defination in sm_make_chunk.c.

Note that it doesn't fix many indents although it should, as sctp_disposition_t's removal would mess them up again. So better to fix them when removing sctp_disposition_t in the later patch.
