Change Details

``` ninja check check-functional ``` Run this before and after patch: ``` ./src/bench/bitcoin-bench -filter=BlockToJsonVerbose ``` Observe ~3-4% speedup. Verify internal linkage: ``` cmake -GNinja -DCMAKE_CXX_FLAGS="-emit-llvm -S" .. ninja univalue grep "define internal" src/univalue/libunivalue.a ``` I was only able to verify internal linkage for writeStream and json_escape. Not the other helper functions.
