./src/H5Ppublic.h
	Added H5Pset_alignment() so that it is now possible to align
	file allocation requests on application-specified
	boundaries. Any request >= the specified threshold will begin
	on an address which is a multiple of the specified
	alignment. Defaults are one for threshold and alignment. The
	alignment is done on relative addresses, so the size of the
	user block can affect the location of the data in the file.

./src/H5D.c
./src/dsets.c
	Added a test for, and fixed the data space caching bug in
	datasets.  Extending a dataset through one handle will cause
	all other handles to the same dataset to get the new dataset
	size.

./src/H5S.c
./src/H5Sprivate.h
	Removed an unused argument from H5S_read() which duplicated
	information from the other argument.

./config/linux
	Made `--enable-parallel' the default on my system.  It used to
	be that way before but then I accidently turned it off and
	forgot about it.

./src/H5Fmpio.c
	Qualified some function arguments with __unused__.  Changed a
	couple places where NULL was returned on error for herr_t
	functions.

./src/H5P.c
	Removed unused autos from H5Pset_mpi().
