of feedback.

dict: Rework reference counting
Use C11 atomics if available. Otherwise, fall back to pthread mutex
inlined in xmlDict struct or Win32 atomics.
This should fix lock contention reported in #970.

relaxng: ensure thread safe global initialization
Relying on a plain integer flag, with no synchronization primitives does
not give thread-safe initialization. All reads & writes of the
xmlSchemaTypesInitialized flag need to be protected by a mutex to ensure
suitable memory barriers & thus correct ordering wrt any speculative
execution.
A separate internal initializer tied to xmlParserInit is used to create
the mutex used for synchronization, similarly to how catalog.c works.

globals: Rework global state destruction on Windows
If DllMain is used, rely on it working as expected. The old code seemed
to attempt to free global state of other threads if, for some reason,
the DllMain mechanism didn't work.
In a static build, register a destructor with
RegisterWaitForSingleObject.
Make public functions xmlGetGlobalState and xmlInitializeGlobalState
no-ops.
Move initialization and registration of global state objects to
xmlInitGlobalState. Lookup global state with xmlGetThreadLocalStorage
which can be inlined nicely.
Also cleanup global state when using TLS. xmlLastError must be reset.

threads: Move library initialization code to threads.c
This allows to consolidate the initialization code since the global init
lock was already implemented in threads.c.

Hide internal functions
These functions were never declared in public headers, so it should be
safe to hide them.
Fixes #139.

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.
