Rework libghdl build/install procedure (#840)

* feat(libghdl): add libghdl_pkg.py, add option to generate libghdl-py.tgz with dist/travis/build.sh

* libghdl*.so is now part of GHDL

* move python sources to python/libghdl and python/pnodes
* rename src/vhdl/python to src/vhdl/libghdl
* add generation of tarball for libghdl-py to the makefile
* deprecate --enable-python and --disable-python
* add configuration option --disable-libghdl

* feat(python/libghdl): add support for LIBGHDL_PREFIX (#844)

* fix(travis): disable libghdl on mac

* feat(python/libghdl): add support for GHDL_BIN_PATH and VUNIT_GHDL_PATH
