Description
It would be nice if the ENVISAT driver could extract more processing parameters (specially for SAR products) that are needed for high level data processing.

The attached patch enables the extraction of metadata from the ASAR ADS and GADS. Since the number of metadata is quite large and it is not appropriate to propagate many of them in case of dataset copy I decided to stored them into the "RECORDS" metadata domain.
Of course it is quite easy to change the policy so please let me know if there are different ideas and I will prepare an amended patch.

Patch applied in trunk in r22485 with a few minor edits :
- some typo fixes in the HTML page
- the code didn't actually compile : the CollectADSMetadata() method was called by CollectRecordMetadata() in the code
- I've added a EnvisatFile_ prefix to the GetRecordDescriptor() and GetFieldAsString() to avoid namespace collisions
- The makefile.vc wasn't updated with the new file
