[xml] [PATCH] DSO/Module Support

[Joel Reed <joelwreed comcast net>]

The following patch implements a basic API for dynamically loading
shared objects (.so/.dll files).

The API is as follows:

XMLPUBFUN xmlModulePtr XMLCALL xmlModuleOpen (const char *filename);       
XMLPUBFUN void* XMLCALL xmlModuleSymbol (xmlModulePtr module, const char* name);
XMLPUBFUN int XMLCALL xmlModuleClose(xmlModulePtr module);                
XMLPUBFUN int XMLCALL xmlModuleFree (xmlModulePtr module);

The guts of the patch can be found in the following files:

libxml2/xmlmodule.c
libxml2/xmlmodule-beos.c
libxml2/xmlmodule-dlopen.c
libxml2/xmlmodule-os2.c
libxml2/xmlmodule-shlload.c
libxml2/xmlmodule-win32.c

Thus far, only xmlmodule-dlopen.c has been tested. I plan on testing
xmlmodule-win32.c next. People with access to beos, os2, shlload-based
platforms - please test out the patch & provide improvements.

I'm posting this for review, and hope that at some point it can be
included into CVS. I've got a 2nd patch to post which uses libxml2
module support to implement XSLT extensions as modules.
