commodities.library jump table

Our open commodities.library: 26 calls with the same LVOs and registers as AmigaOS 3.2's, checked against the NDK 3.2 .fd file.

commodities.library's jump table, as OpenCommodities builds it: LVO, call, registers. build-amiga.sh (with ../common/check_fd.py) checks this against the NDK 3.2 commodities_lib.fd in the stove and stops on any difference; opencommodities_lib.c's lib_vectors[] follows it line for line. The fd keeps -108 and -186..-198 private; ours are, in order, a slot that answers 0, then CopyBrokerList(list)(a0), FreeBrokerList(list)(a0) and BrokerCommand(name,id)(a0/d0), the calls Exchange makes. Core class (OPEN_LIBRARIES.md, section 5): ParseIX, MatchIX, CxMsgType, CxMsgData, CxMsgID and InvertKeyMap are pure; every other call is locked (the object tree and the broker list, one semaphore); the input handler that routes events runs on input.device's task (anchored).
