Java conversion: LINK / XCTL / CALL targets (incl. data-driven and remote SYSID) -> service-to-service calls

[squid-protocol]

Resolved call targets become injected service calls (in-process beans), remote (SYSID / DPL) targets become HTTP clients, per the config; unresolved dynamic targets become an explicit dispatch point with their candidates.

Part of the COBOL→Java conversion epic.
