[xml] xmlSaveFormatFileTo

[Joe McAlerney <joey SiliconDefense com>]

Hello,

These patches add the following function:

int xmlSaveFormatFileTo (xmlOutputBuffer *buf, xmlDocPtr cur, const char
*encoding, int format); 

It's essentially a cross between xmlSaveFormatFile() and
xmlSaveFileTo().  Others may find it useful.  The patches should be
applied to the CVS version.

Cheers,

-Joe M.
