Why do we export "JVM_handle_xxx_signal"?

[Ioi Lam]

I have no idea, but this symbol has been exported since we moved the 
HotSpot source code from SCCS to Mercurial in 2008. It's probably 
vestige from the early days of Java.

http://hg.openjdk.java.net/jdk7/modules/hotspot/annotate/9646293b9637/make/linux/makefiles/mapfile-vers-product#l244

I checked all .so files in our JDK build and no one uses 
JVM_handle_linux_signal. I think it's probably safe to hide it. We 
should probably drop the JVM_ prefix, since this function is not 
declared in jvm.h.
