SCCP: implement variable limit on Optional Data (CR,CC,CREF,RLSD)
When the Optional Data surpasses 130 bytes, it is not sent as part of
SCCP CR, CC, CREF or RLSD messages, but gets sent separately in a Data
Form 1.
Make this 130 user configurable. This is specified to be 130 bytes
exactly, but to interop with non-conforming peers, make this limit
adjustable per cs7 instance, via osmo_sccp_vty_init().
Add and test new VTY config:
cs7 instance N
sccp max-optional-data (<0-999999>|standard)
