Subject: [PATCH net-next 00/24] sctp: support SCTP_FUTURE/CURRENT/ALL_ASSOC

This patchset adds the support for 3 assoc_id constants: SCTP_FUTURE_ASSOC
SCTP_CURRENT_ASSOC, SCTP_ALL_ASSOC, described in rfc6458#section-7.2:

   All socket options set on a one-to-one style listening socket also
   apply to all future accepted sockets.  For one-to-many style sockets,
   often a socket option will pass a structure that includes an assoc_id
   field.  This field can be filled with the association identifier of a
   particular association and unless otherwise specified can be filled
   with one of the following constants:

   SCTP_FUTURE_ASSOC:  Specifies that only future associations created
      after this socket option will be affected by this call.

   SCTP_CURRENT_ASSOC:  Specifies that only currently existing
      associations will be affected by this call, and future
      associations will still receive the previous default value.

   SCTP_ALL_ASSOC:  Specifies that all current and future associations
      will be affected by this call.

The functions for many other sockopts that use assoc_id also need to be
updated accordingly.
