jijinbei	875291c4d9	shim: share identical C++ helpers through sc_sm.h, sc_nlib.h, sc_gw.h ... 125 shims carried private copies of the same small helpers (put_vec, st, nl_status, Rd, dump_crv, read_nurb, ...). Move the most common, byte-identical form of each into three headers grouped by the upstream API they need, and have those shims pull them in with `using sc::<name>;`. Shims with a different variant keep their own copy; files touched by open PRs are left alone. `the_context()` stays per shim (its function-local SmContext must not be shared).
