…uation and variable substitutions mysqltest had limited scripting capabilities, requiring complex workarounds for mathematical calculations and string manipulations in test cases. This commit solves these limitations by adding a new `$(...)` syntax that enables direct evaluation of mathematical, logical, and string expressions within test scripts. Expression Evaluation (MDEV-36107): - Recursive descent parser supporting arithmetic, logical, comparison, and bitwise operators with proper precedence - Support for integers (decimal, hex, binary), booleans, strings, and NULL values - Variable substitution within expressions - Integration with existing mysqltest control flow String Functions (MDEV-36108): - Base conversion functions supporting bases 2-62 - String manipulation and processing functions - Regular expression functions - Conditional and numeric utility functions The implementation enhances mysqltest's scripting capabilities while maintaining full backward compatibility.
