Validate: add message parameter construction via elllipsis notation to speed up 
processing
------------------------------------------------------------------------------------------

                 Key: LANG-508
                 URL: https://issues.apache.org/jira/browse/LANG-508
             Project: Commons Lang
          Issue Type: Improvement
    Affects Versions: 2.4
            Reporter: Mark Struberg
             Fix For: 3.0


Currently passing verbose message strings to a log of commons.lang.Validate 
functions costs a lot of performance.

A typical usecase currently is:

{noformat}
Validate.isTrue (argInt1.intValue > argInt2.intValue, "param2 actually is " + 
argInt2 + " but must larger than param1 " + argInt1 +" !");
{noformat}
So all the string operations get executed regardless if the validation fails or 
not.

This can be made perform much better by moving all the string operations inside 
the respective validation function and execute it only if the validation fails:
{noformat}
Validate.isTrue(argInt1.intValue > argInt2.intValue, "param2 actually is {1} 
but must larger than param1 {0} !", argInt1, argInt2);
{noformat}
