Remove some dead code

Ruby driver tests passing after initial refactor

* Set up tables for each test
* Clean up random tables after tests
* Move duplicate code into helper module
* Make tests independent of order (hopefully)
* Replace global variables with method calls
Reformatting code, swap assert_equal order

assert_equal order should be expected, actual. Doing this the right way
gives better error messages.
Handle case results composed of ONLY empty object + fix resize + fix render_metadata
Merge branch 'next' into sam_47
Merge branch 'sam_nofsck' into sam_47
Move nested methods to helper module

nesting methods in Ruby does not affect scope
Made the linux_file_t construction API be such that non-open objects are inconstructible by API.  Also removed the method exists() which would have always returned true and was brokenly implemented anyway.
Removed the unused exists() method from mock_file_t.
Removed unused serializer function check_existing.
