Rip out the file object's implementation.

Fixed test_import.py while I was at it.

However, there's still a problem in import.c -- get_file() can leak a
FILE struct (not a file descriptor though).  I'm not sure how to fix
this; closing the FILE* closes the file descriptor, and that's the
wrong thing to do when there's still a Python file object keeping the
file descriptor open.  I also would rather not mess with dup(), as it
won't port to Windows.

-Routine to get next line using platform fgets().
-
-Under MSVC 6:
-
-+ MS threadsafe getc is very slow (multiple layers of function calls before+
-  after each character, to lock+unlock the stream).
-+ The stream-locking functions are MS-internal -- can't access them from user
-  code.
-+ There's nothing Tim could find in the MS C or platform SDK libraries that
-  can worm around this.
-+ MS fgets locks/unlocks only once per line; it's the only hook we have.
-
-So we use fgets for speed(!), despite that it's painful.
-
-MS realloc is also slow.
-
-Reports from other platforms on this method vs getc_unlocked (which MS doesn't
-have):
-	Linux		a wash
-	Solaris		a wash
-	Tru64 Unix	getline_via_fgets significantly faster
-
-CAUTION:  The C std isn't clear about this:  in those cases where fgets
-writes something into the buffer, can it write into any position beyond the
-required trailing null byte?  MSVC 6 fgets does not, and no platform is (yet)
-known on which it does; and it would be a strange way to code fgets. Still,
-getline_via_fgets may not work correctly if it does.  The std test
-test_bufio.py should fail if platform fgets() routinely writes beyond the
-trailing null byte.  #define DONT_USE_FGETS_IN_GETLINE to disable this code.
-**************************************************************************/
-
-/* Use this routine if told to, or by default on non-get_unlocked()
- * platforms unless told not to.  Yikes!  Let's spell that out:
- * On a platform with getc_unlocked():
- *     By default, use getc_unlocked().
- *     If you want to use fgets() instead, #define USE_FGETS_IN_GETLINE.
- * On a platform without getc_unlocked():
- *     By default, use fgets().
- *     If you don't want to use fgets(), #define DONT_USE_FGETS_IN_GETLINE.
