Add retry logic for AV defense to winOpen. Also, refactor test suite to allow the key Tcl file operations (e.g. copy and delete) to be retried.

#
# When both a main database table and a TEMP table have the same name,
# and a main database trigge is created on the main table, the trigger
# is incorrectly bound to the TEMP table. For example:
#
#   CREATE TABLE t1(x);
#   CREATE TEMP TABLE t1(x);
#   CREATE TABLE t2(z);
#   CREATE TRIGGER main.r1 AFTER INSERT ON t1 BEGIN
#     INSERT INTO t2 VALUES(10000 + new.x);
#   END;
#   INSERT INTO main.t1 VALUES(3);
#   INSERT INTO temp.t1 VALUES(4);
#   SELECT * FROM t2;
# 
# The r1 trigger fires when the value 4 is inserted into the temp.t1
# table, rather than when value 3 is inserted into main.t1.

# The following syntax really should not be allowed:
#
#    CREATE TRIGGER xyz.trig BEFORE UPDATE ON xyz.tab BEGIN ...
#
# But a long-standing bug does allow it.  And the "xyz.tab" slips into
# the sqlite_master table.  We cannot fix the bug simply by disallowing
# "xyz.tab" since that could break legacy applications.  We have to 
# fix the system so that the "xyz." on "xyz.tab" is ignored.
# Verify that this is the case.
