25afd931fc xmlschemastypes: Remove unreachable if statement 
Pointer `cur` is created by `value` variable and there is no
need to check `cur` for NULL because of `value` is checked
in the beginning of function.

06c00f6582 schemas: Improve error handling 
Introduce xmlSchema*ErrFull which checks for memory allocation failures
during error reporting.

Remove arguments from memory error handlers.

Use xmlRaiseMemoryError.

f8efa589e8 malloc-fail: Handle malloc failures in xmlSchemaInitTypes 
Note that this changes the return value of public function
xmlSchemaInitTypes from void to int. This shouldn't break the ABI on
most platforms.

0f568c0b73 Consolidate private header files 
Private functions were previously declared

- in header files in the root directory
- in public headers guarded with IN_LIBXML
- in libxml.h
- redundantly in source files that used them.

Consolidate all private header files in include/private.

2070ade6df Undeprecate schema init functions 
These functions aren't called from xmlInitParser, so it's better to keep
them public for now.

40483d0ce2 Deprecate module init and cleanup functions 
These functions shouldn't be part of the public API. Most init
functions are only thread-safe when called from xmlInitParser. Global
variables should only be cleaned up by calling xmlCleanupParser.

966b0f21c1 Add whitespace folding for some atomic data types that it's missing on. 
XSD validation fails when some atomic types contain surrounding whitespace
even though XML Schema Part 2: Datatypes Second Edition, section 4.3.6
says they should be collapsed. Fix this.

(I am not sure whether the test is correct.)

cb7a572b3e xmlschemastypes.c: xmlSchemaGetFacetValueAsULong add, check "facet->val" 
The xmlSchemaGetFacetValueAsUlong() API is an external API.
The validity of external input parameters must be strictly verified.
Before accessing "facet->val->value", we need check whether "facet->val" is
a null pointer.

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

90da33cebe Portability to non C99 compliant compilers 
OS400 C compiler is not C99 compliant.
It only supports local variable declarations at the beginning of a block.
We loose the const as a result but portability is more important.

30cf439efc Check for tmon in _xmlSchemaDateAdd() is incorrect 
For https://bugzilla.gnome.org/show_bug.cgi?id=732705
In _xmlSchemaDateAdd(), the check for |tmon| should be the following
since MAX_DAYINMONTH() expects a month in the range [1,12]:

    if (tmon < 1)
	tmon = 1;
