fa396948 Fix(pynn-brainscales): Enforce correct log4cxx version

Eric Müller authored 3 years ago and Athanasios Karmas committed 3 years ago

The production env seems to use a newer spack repo state → log4cxx is
newer than currently supported for BrainScaleS → quickfix: pin to old
version.


(cherry picked from commit fa396948)

That's the first version that should really work :); rc1 experienced
scheduling problems when multiple users were accessing the same hardware
resource in parallel.

Add specs in spack.yaml. Update names for pyaescrypt and formencode and specify them as dependencies for tvb-framework.

`meta-brainscales` depends on `genpybind` which previously enforced
older versions of `llvm`.

This introduces some LLVM patches to enable code generation via
genpybind.
