update project template

The upcoming version of the config generator script package will need
more files to be copied into the build directory. This change simply
copies all files and does not rely on a particular structure.

This is the implementation for the specification change done in a recent
commit.

May occur when not mapping a Void variable in the control system so it
is being optimised out.

This happens if the control system adapter optimises out the PV.

A PV which is received by a module and also used as a trigger for a
DeviceModule was "deleted" from the model, if the module is unregistered
from its owner. This deletion is now prevented by adding a trigger
relationship to the model (which was anyway missing).

Note: the "deletion" never was a real deletion, instead only all
relationships are removed. As a consequence, the DeviceModule was still
pointing to the "deleted" vertex resulting in a wrong connection later.

* Use correct of version pthread_setname_np depending on platform.

On Linux, this function takes two parameters. On most other platforms
(including all BSD-based platforms) it only takes a single parameter.

* Omit -Wl,--export-dynamic flag on macOS.

This flag is not supported on Clang / LLVM and on macOS it is not needed
anway because exporting all symbols is the default behavior.

When using Clang on other platforms (e.g. Linux) --export_dynamic or
-rdynamic might have to be specified instead.

* clang compiler compatibility
