The error and message handlers used by the freetds library were getting
reset to back to the default every time a database was opened. The
Qt TDS SQL driver was calling dbinit() from QTDSDriver::open(). This
had two problems:
1. dbinit() would reset the error handler previously set by a call to
dberrhandle(). A db error would then cause the application to
abort.
2. freetds expects dbinit() and dbexit() to be called symmetrically.
Opening multiple database connections would result in freetds not
cleaning up on application close.
Solved by moving the dbinit() call into the QTDSDriver constructor.
