e03f0a199a Fix hash callback signatures
Make sure that all parameters and return values of hash callback
functions exactly match the callback function type. This is required
to pass clang's Control Flow Integrity checks and to allow compilation
to asm.js with Emscripten.

Fixes bug 784861.

454e397eb7 Porting libxml2 on zOS encoding of code
First set of patches for zOS
- entities.c parser.c tree.c xmlschemas.c xmlschemastypes.c xpath.c xpointer.c:
  ask conversion of code to ISO Latin 1 to avoid having the compiler assume
  EBCDIC codepoint for characters.
- xmlmodule.c: make sure we have support for modules
- xmlIO.c: zOS path names are special avoid dsome of the expectstions from
  Unix/Windows

95ebe53b50 Fix and add const qualifiers
For https://bugzilla.gnome.org/show_bug.cgi?id=689483

It seems there are functions that do use the const qualifier for some of the
arguments, but it seems that there are a lot of functions that don't use it and
probably should.

So I created a patch against 2.9.0 that makes as much as possible const in
tree.h, and changed other files as needed.

There were a lot of cases like "const xmlNodePtr node".  This doesn't actually
do anything, there the *pointer* is constant not the object it points to. So I
changed those to "const xmlNode *node".

I also removed some consts, mostly in the Copy functions, because those
functions can actually modify the doc or node they copy from
