    detect solaris 10 to avoid certain POSIX expressions

    Another attempt at fixing for solaris without regressing POSIX platforms.
    
    1) use `uname` to detect solaris 10 platform.  Could not figure out a way via feature-detection to make change specific to the heirloom-sh found on it. Can be overridden via env PROTECT_NL=true|false.
    2) esc_arg sed line is now done with `` instead of $(), due to heirloom compatibility.
    3) ant_exec_debug final printing should have used printf instead of echo for accuracy of output
    4) padding protection only was needed on the end of the processing argument and only for non-heirloom.
    
    
    I tested with arguments for empty-string and the 6 most special characters (dollar, double-quote, backtick, singlequote, backslash, newline):
    
    --execdebug -version '' '$' '"' '`' "'" '\\' '
    '
    
    Worked on ubuntu 14.04, and with Solaris 10 with the caviat newlines get trimmed from arguments on Solaris 10 e.g. the newline-only argument was translated into an empty-string.
