1. Replaced shared variables with a normal variable, and global signals with
 
   a normal signal.
 
   VHDL-2000 and later requires that shared variables use protected types,
 
   but protected types weren't available in earlier VHDL versions.
 
   As a consequence, some simulators in VHDL-200x mode require protected
 
   types. But some simulators still don't support protected types at all.
 
   To make pltbutils work in all (or at least in most) VHDL simulators,
 
   shared variables have now been removed.
 
   In previous versions of pltbutils, protected types were used by default.
 
   There were comments in the pltbutils code as an aid to modify the code
 
   for simulators that don't support protected types, but it was too much
 
   work to do the modifications. One possible solution could have been to
 
   make separate variants of pltbutils; one with, and one without protected
 
   types. But that solution was not tempting.
 
2. Removed src/vhdl/pltbutils_type_pkg.vhd .
 
3. Added doc/required_updates.txt .
