Structure/union and variable definition files

In order to add new structure definitions to scodb, do the following:

1. Generate an object module (a .o file) which #include's the structures of interest. This must be compiled with the cc -g -W0,-d1 option to generate DWARF I format debugging information. Ensure that you build the object with make flags matching the DEBUG/non-DEBUG UNIPROC/non-UNIPROC status of the kernel in which scodb is installed.

   ---

   NOTE: Do not use the filename ``kstruct.o'' for this module, as this file already exists and contains the core kernel structure definitions.

   ---

2. Copy the new object module into the /etc/conf/pack.d/scodb/info directory.

3. At this point, the structure definitions will be automatically added to scodb.
