[svn-r411] Added data-transfer-mode to various function to specify which
mode to use for data transfer. Currently, INDEPENDENT transfer is the default mode. Collective is supported for files opened via the MPIO driver. Specific changes to individual files follow. H5D.c: Replaced previous kludge of passing xfer_mode via the file access_mode with xfer_mode function parameter all the way to the low level I/O drivers. H5Dprivate.h: The H5D_xfer_t.xfer_mode is now used in serial and parallel modes. Removed the "HAVE_PARALLEL" macro condition to support it. H5Dpublic.h: Added H5D_XFER_DFLT as a new value for H5D_transfer_t and removed the HAVE_PARALLEL condition macro to make the H5D_transfer_t definition available to both serial and parallel version. H5B.c: H5F.c: H5Farray.c: H5Fcore.c: H5Ffamily.c: H5Fistore.c: H5Flow.c: H5Fmpio.c: H5Fsec2.c: H5Fsplit.c: H5Fstdio.c: H5Gnode.c: H5HG.c: H5HL.c: H5O.c: H5Sprivate.h: H5Ssimp.c: debug.c: Added xfer_mode to the argument lists of the following routines to specify data transfer mode. Then updated calls to these routines with appropriate transfer mode. Whenever cases that collective mode is inappropriate (e.g. object header read-write, flush), H5D_XFER_DFLT is used. The H5D_XFER_DFLT mode is currently acting the same as the independent mode.

The access-mode was the initial design to control independent or collective I/O mode. It is now supported by the data transfer mode.
