JASSIST-234.  Support Javaflow NEW bytecode pattern for replacement.

did minor refactoring.

If foo.Bar.Baz is a nested class in foo.Bar, then the argument of
@MyAnnotation(foo.bar.Baz.class) could not be obtained.
The test code is javassist.JvstTest4#testAnnArg().

Fix for JASSIST-220

Static methods on interfaces in Java 8 means
that the INVOKESTATIC opcode can sometimes refer
to an item that is an InterfaceMethodrefInfo
(instead of a MethodrefInfo).

This is now handled in the
ConstPool.getMethodref...() methods by casting
to MemberrefInfo instead (since MemberrefInfo
contains all the needed information).

To get the test case JvstTest4.testMethodParameters() to work
the <testSource> and <testTarget> elements are set to "1.8"
and the compiler argument "-parameters" is added.

Fix typos in the tutorial.
