[svn-r579] Changes since 19980806

----------------------

./config/solaris2.5
	Hopefully set up now so it honors the CC and CFLAGS variables
	and understands solaris cc flags.

./test/big.c
	Checks to see if creating lots of large sparse files exceeds
	the user disk quota and skips the test.  It also checks that
	we can actually open ~64 files at once.

./doc/html/Files.html
./src/H5A.c
./src/H5Aprivate.h
./src/H5F.c
./src/H5Fpublic.h
	Added the H5Fflush() function which takes any object as an
	argument as long as the object is in some way associated with
	a file.  This required an H5A_entof()

./src/H5.c
./src/H5Flow.c
	The `%a' format of HDfprintf() now allows a field width and
	justification flag etc, like the other formats.  The old
	H5F_addr_print() was recoded to call HDfprintf() instead of
	vice versa.
