Add new PPIDs 56 and 57. When sending an empty message,
we use the corresponding PPID with a single byte data chunk.
On the receiving side, when detecting such a PPID, we just
ignore the payload content.

The race occurs if the transport is being destroyed at the same time as
a callback occurs on the usrsctp timer thread (for example, for a
retransmission). Fixed by slightly extending the scope of mutex
acquisition to include posting a task to the network thread, where it's
safe to do further work.

When deinitializing usrsctp, we attempt to call usrsctp_finish in a loop
for three seconds (it may fail because another sctp thread is holding a
reference to something). If the three seconds run out, usrsctp is left
in a still initialized state, and bad things happen down the road if
usrsctp_init is called in the state.

When processing an INIT for existing SCTP association, which may happen
when transferring to a new remote endpoint, if there are chunks still on
the output queue, an SCTP_SEND_FAILED_EVENT notification will be
delivered while holding the INP lock. When processing this notification,
WebRTC was calling usrsctp_getladdrs in order to look up the
SctpTransport* associated with the socket, but this also tries to
acquire the INP lock, resulting in a deadlock.
The temporary fix is to simply not subscribe to the
SCTP_SEND_FAILED_EVENT notification; it was only used for logging
anyway.

OnSctpInboundPacket is called not only for incoming packets, but for
notifications, which can be delivered on the usrsctp timer thread.
I suspect that these notifications can be delivered after we attempt to
close the socket, because if we attempt to close it while the timer
thread holds a reference, it isn't actually destroyed until the timer
thread finishes its operation.

reducing the threshold (from 128KB to 64KB) seems to mitigate the issue.
Can set it back once the root cause is fixed, though this isn't

Patch originally submitted by Lennart Grahl:
https://webrtc-review.googlesource.com/c/src/+/177527
SCTP message chunks and notifications are being delivered interleaved.
However, the way the code was structured previously, a notification
would interrupt reassembly of a message chunk and hand out the partial
message, thereby violating message integrity. This patch separates the
handling of notifications and reassembly of messages.
Additional changes:
- Remove illegal cast from non-validated u32 to enum (PPID)
- Drop partial messages if the SID has been changed but EOR not yet
received instead of delivering them. (This should never happen
anyway.)
- Don't treat TSN as timestamp (wat)
- Replace "usrsctplib/usrsctp.h" with <usrsctp.h>, allowing a hack
to be removed from media/BUILD.gn

We were using the address of the SctpTransport object as
the sconn_addr field in usrsctp, which is used to get access to
the SctpTransport object in various callbacks.
However, this address is sent in the clear in the SCTP cookie,
which is undesirable.
This change uses a monotonically increasing id instead, which
is mapped back to a SctpTransport using a SctpTransportMap helper
class.

Tests the behavior of the usrsctp library buffering a large message in
unordered mode. The expected behavior is that this message will be sent
when the socket becomes unblocked, but instead an SCTP_SEND_FAILED_EVENT
is fired by usrsctp library and the message is never sent. This test
will pass with a newer version of usrsctp lib, or if the send is in
ordered mode.

partially accepted by usrsctp.
