Some of context fields which must be overrided by this wrapper decoder
may be set and used by user, so we have to save and restore them before
and after invoking the inner decoder to secure user.

  configure: Don't use symlinks for creating the out of tree makefile
Merged-by: Michael Niedermayer <michaelni@gmx.at>

On some platforms (such as msys), symlinks are (poorly) emulated
by simply creating a copy of the file.

This means that when building out of tree, the build tree gets
a copy of the original makefile, which can lead to unintuitive
build errors when the original makefile gets updated later.

Instead simply create a stub makefile which includes the real
one.
