Summary: Partition Table Sanity Checking

Initial Comment:
Currently, TSK  stops processing a partition table when it finds a partition that starts outside of the image. Perhaps this should be relaxed so that it reports the results and then the user needs to figure out that it does not fit.... Reported by Simson Garfinkel.

Note for Brian: This can be seen in the AV iso image from Simson.

Committed revision 117.

Fixed by only checking the first couple of partition table entries.  This
allows some sanity checking while allowing for some missing sectors. If
this is still an issue, we'll need to push down the notion of when we are
testing if data is really a given data type versus when it is specified and
we can be more liberal when we are told that it is a given type and more
conservative with sanity checking when we are guessing.
