[PATCH] Handling input encoding

[Steve Quint]

Now that there's some activity going on, would it be possible to have 
this patched against XMLRPC_1_2_BRANCH and HEAD.  This patch makes it 
possible to specify an encoding in the case where the remote endpoint 
is specifying the encoding in the response header.

  Log:
  Allow the input encoding used to be overridden.
  The default input encoding is 'null' which produces the
  orignal behaviour.
  Overriding the input encoding is necessary on platforms
  like BS2000 or IBM z/OS where the default encoding (often
  an EBCDIC variant) is not the same as the network encoding
  (which for XML-RPC is defined to be ASCII).
I was hoping that this would allow me to handle input encoding, but I
just had a chance to look at this patch and it just falls short.
My problem:  I wish to explicitly set the input encoding for XMLRPC
responses that do not contain the proper encoding information in the XML
declaration.  Some vendors (and I believe this to be valid) will set the
document encoding in the content-type *header*.  Others vendors will
omit encoding information altogether, but will always encode the
response a particular way.
Using the above patch to set the encoding for each instance is not
thread safe.  There's also no appropriate method that we can override in
the XmlRpc class (such as a protected "getInputSource" method).
I've included a patch for setting the encoding for each instance of the
XmlRpc object.
