/*
Generate a simple route table (for all but direct route table testing).
This gets tricky inasmuch as we generate two in one; first a whole table
and then two update tables. The first is a table with a bad counter in the
last record to test that we don't load that table and error. The second
is a good update. The same applies to the meid map; first has a bad counter
and some bad records to drive coverage testing. The end should leave a good
meid map in the table.
Once the file is generated, it is forced in via static read and the file
is unlinked.
