Proposal: Export InitializeEncoding for JVM access

[Andrew Leonard]

Hi,
I would like to propose and find a sponsor for this change please, which 
is is export from libjava the JNU_InitializeEncoding() method, so that a 
JVM can initialize the platform encoding. Currently 
Java_java_lang_System_initProperties initializes the encoding, however for 
a generic JVM that will naturally provide it's own System implementation, 
the JVM needs a way to initialize this encoding directly. We can thus 
simply export it as per the change below.. There is precendence for doing 
this sort of export with Canonicalize().
Thanks
Andrew
