2010.03.15 : converting libohana / libfits to handle large files:

  * need to change all file I/O operations to be largefile safe:
    * fseek -> fseeko + offset -> off_t
    * read / fread -> size & nmemb -> off_t
    * write / fwrite -> size & nmemb -> off_t
    * ftell -> ftello + offset -> off_t

  * I am changing FILE not IO interactions (thus CommOps.c & IOBuffers.c do not change)

  * in Ohana : Fread, Fwrite, Fseek, ByteSwap 

  * in libfits:
    * added lld, llu, Ld, Lu support for gfits_scan, gfits_print, gfits_modify
    * Header, Matrix, FTable, VTable : 
      * size -> datasize (off_t)
      * Naxis[i] -> off_t
      * row, Nrow, pad -> off_t

  * need to search for NAXIS1,2,3 etc
  * need to search for tables
  * need to search for fseek, read, write functions
