[svn-r21411]

Description:

 - Remove H5FD_mpiposix_flush function. I initially added it
   so the mpiposix driver had a place to coordinate the EOF
   value amongst all processes, but that was before we
   decided to introduce the H5FD_coordinate set of callbacks
   as a more appropriate place to do this. I just forgot to
   remove this function.

 - Add H5Fquery function for avoid_truncate and tie it to an
   associated H5F_AVOID_TRUNCATE() macro.

+ * Function:    H5F_avoid_truncate
+ *
+ * Purpose:     Quick and dirty routine to determine if the library
+ *              is avoiding truncating this file.
+ *          (Mainly added to stop non-file routines from poking about in the
+ *          H5F_t data structure)
+ *
+ * Return:      TRUE/FALSE on success/abort on failure (shouldn't fail)
