Tracing

A tracing capability has been added to all drivers and the driver manager (dbkernel). The tracing functionality can be activated either:

1. Using environment variables (ILD_TRACE_LEVEL, ILD_TRACE_OUTPUT) read only on application startup or

2. Using the dedicated API IldSetTraceContext if the header file <ildblink/ildtrace.h> was included. Four trace levels are possible and can be mixed (see the DB Link Reference Guide).

The environment variable setting can be overwritten using the API. The advantage doing this is that no changes need to be made in existing code.
