Remove the __NO_CTYPE define

Nothing within the project uses it, and it's not necessary to
build the project either, tested on both linux and mingw.
Remove the MSVC 2010 and 2012 project files

Only the 2008 version is kept up to date at the moment.

The newer versions of MSVC can open and upgrade the 2008 version
files anyway, so by removing the unmaintained ones we reduce the
confusion and maintainance burden.

Additionally, the preferred way of building with MSVC is with the
makefile build system, according to the readme.
Remove/disable broken code for loading the encoder library from a macos bundle

This refers to a file "bundlewelsenc.h" which doesn't even
exist in the project at the moment.

The corresponding bundle loading code is not called at all
in the decoder console tool.

Remove an exclude of an nonexistent file
Fix building of macos bundle loading code on 64 bit
Remove an unused function

whose use is unknown.

on linux still works just fine.
Only build the thread code if multithreading is enabled

This allows including the source file in the build even if
multithreading isn't desired.
Move the WelsThreadLib files to the common directory/library

This simplifies building the thread library code via the
makefile based build system.
