BTrace对依赖的asm包的包名进行了重命名

This directory contains btrace-asm-4.0.jar. This file was

generated from "asm-4.0.jar" using the "JarJar" tool (please

see http://code.google.com/p/jarjar/) using the following rule:

    rule org.objectweb.asm.** com.sun.btrace.@0

i.e., We prefix every ASM class with "com.sun.btrace" so that 

the BTrace will not clash with application's use of ASM (if any).

Also, this will allow us to trace application's ASM usage as well.

Such renaming of ASM classes has indeed been suggested in ASM FAQ 

at http://asm.objectweb.org/doc/faq.html.
