VHDL: Add support for identifying inherited packages

[chaseruskin]

The following code is found in OSVVM:

package ScoreBoardPkg_slv is new work.ScoreboardGenericPkg
  generic map (
...
);

It appears to create a specific instance of ScoreboardGenericPkg. VHDL file analysis must make sure to catch this and create the dependency for ScoreBoardPkg_slv to depend on ScoreboardGenericPkg.

Here is an overview of VHDL-2008 features that will need more investigation.

The OSVVM packages are now supported with this dependency feature from VHDL-2008. This issue is closing, but eventually more investigation into the 2008 std will be needed to create more robust VHDL file analysis process.
