Two standard Harbour functions that fivenode-style PRG code (bridge_*.prg
and downstream apps) calls frequently. Without them, every reference
emits an analyzer WARN and resolves to NIL at runtime.
* hb_HGetDef(hHash, xKey, xDefault) — hash lookup with fallback.
* PValue(nIndex[, xDefault]) — read the nth parameter of the calling
PRG function. Mirrors the PCount pattern: needs the caller frame's
paramCount and locals, exposed via new hbrt.Thread.CallerLocal helper
that pairs with the existing CallerParamCount.
Registered under PVALUE and HB_PVALUE (Harbour accepts both forms).
Verified: hb_HGetDef / PValue / HB_PVALUE all return expected values for
present-key, missing-key-with-default, missing-key-no-default, and
out-of-range-param cases. Full regression: go test (18 packages) +
Compat 56/56 + std.ch 17/17 + FRB 7/7 + FiveSql2 43/43 all green.
