Bug 568033 - IllegalArgumentException in StyledText.replaceTextRange()

Fixed to no longer throw exception if \r\n were on different lines
already.

Even though the test snippet reproduces exactly the stack as reported by
users, I do feel that users might be having a different problem. This
feeling mostly comes from the fact that we only received reports on
Windows in combination with 'WM_IME_COMPOSITION', while the snippet
reproduces the problem on all 3 platforms.

For this reason, I also changed 'DefaultContent.isValidReplace()' to
throw 3 different exceptions with additional info to help future
debugging if this patch doesn't solve the problem.

I didn't find any outside uses of 'DefaultContent.isValidReplace()', so
I think that it's OK to remove 'protected' and change signature.
