[svn-r343] First implementation of collective access support.
H5D.c
Changed H5D_write and H5D_read to recognize collective transfer
requests. Current algorithm puts the xfer-mode in the file->mpio
structure. Not thread safe. Need to revise it to pass transfer
parameter as a function parameters to the lower levels.
H5Dprivate.h
H5Dpublic.h
Added xfer_mode to the transfer property list structure.
Added defination of transfer modes, H5D_XFER_INDEPENDENT and
H5D_XFER_COLLECTIVE.
H5Farray.c
Added code to handle collective access requests. Currently
works for one contiguous block at a time. Need to revise
it with the MPIO low level calls to combine all blocks as
one truely collective call.
H5P.c
H5Ppublic.h
Added H5Pset_xfer and H5Pget_xfer routines that can set and get
the transfer mode of a data transfer property list.
