John Cupitt 233cbf1f15 get all fopen()s going through util.c 
Add a text_mode flag to im__file_open_write() and _read() so we can
route all fopen() though these two functions.

John Cupitt 663c3c15fd fits reader is lazy 
The fits reader is now lazy, and reads out whole tiles when it can.
Previously it read a scanline at a time, and used WIO.

We read in planes and combine with a set of im_bandjoin().

Use an im_flipver() at the end to get rows in the right order.

John Cupitt 5e366bcaf3 fits reader is now lazy 
The fits format reader now uses fits_read_subset() to erad pixels
lazilly. There are a few unresolved issues though:

- getting some streaking, try putting a lock around the read
  subarea call, perhaps it can't thread?

- add a tile cache, cf. tiff

- test colour read with valgrind

- ask Doug for a test colour image

- read whole tiles, if the alignment is right, again see tiff reader

- test performance

- remove the old scanline reader?
