Updated version

[vegarringdal]

I tried to make new version of a updated version of libxml2
Did not go well, making old version was ok. but looks like libxml2 have changed.

I just tried to manually add the xmlvalidate.c to libxml2_la_SOURCES in the makefile.am.
But no xmlvalidate.o gets generated.

Figured I could ask if you see what is needed, so I get a better start.

Think i actually go it working...

Hint to myself for later, if validation works and I need to clean this up..

post.js -> rename addOnPreMain to addOnInit

emmake.sh (commented the path and updated exported functions

#! /bin/sh

cp xmlvalidate.c libxml2

cd libxml2

#patch -N < ../Makefile.am.patch
[ -f ./Makefile ] || emconfigure ./autogen.sh --with-minimum --with-schemas --disable-shared
emmake make

mv xmlvalidate.wasm xmlvalidate.js ../dist
cd ..

int the makefile.am of newest libxml2 I added this to xmlCatalog?sources

xmlcatalog_SOURCES=xmlcatalog.c buf.c chvalid.c dict.c entities.c encoding.c error.c xmlmodule.c \
