    stdio-common: Add tests for formatted vasprintf output specifiers
    
    Wire vasprintf into test infrastructure for formatted printf output
    specifiers.
    
    Owing to mtrace logging these tests take amounts of time to complete
    similar to those of corresponding asprintf tests, so set timeouts for
    the tests accordingly, with a global default for all the vasprintf
    tests, and then individual higher settings for double and long double
    tests each.
