Log Message:
-----------
perf: improve performance of replacing JDBC {...} escapes (#1230)

There are the key improvements:
1) Function arguments for {fn ...} were parsed twice
2) EscapedFunctions now appends data to existing StringBuilder instead of producing intermediate Strings
3) EscapedFunctions.getFunction avoids string concatenation (suggested by benbenw) and toLowerCase on a hot path

closes #1229
