[svn-r745] Changes since 19981002

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

./doc/html/H5.format.html
./src/H5HG.c
	Fixed a bug in the global heap that caused H5HG_read() to
	write past the end of the buffer in certain cases.

./test/big.c
	The test is skipped if hdf5 was configured with
	`--disable-hsizet'.

./src/H5Ofill.c
	Data type conversions are implemented for the fill value.

./src/H5.c
	Tracing prints one of H5P_FILE_CREATE, H5P_FILE_ACCESS,
	H5P_DATASET_CREATE, H5P_DATASET_XFER, or H5P_MOUNT instead of
	the more cryptic H5I_TEMPLATE_* constants.

./src/H5D.c
	Removed prototype for H5D_find_name().

./src/H5I.c
	The GROUP_MASK and ID_MASK are both calculated from GROUP_BITS
	instead of being set by hand.

	We don't use the sign bit of hid_t; all valid hid_t values are
	positive so we can say things like `if ((file=H5Fopen(...))<0)'.

	Changed `(int)pow(2.0,x)' to `1<<x' so we don't have to worry
	about rounding.

	Fixed H5I_get_type() so it doesn't always fail an assertion.

./src/H5E.c
./src/H5Epublic.h
	Added minor error H5E_MOUNT

./src/H5F.c
./src/H5Fprivate.h
	Added H5Fmount() and H5Funmount().  Mounting and unmounting
	works as documented but some of the other things aren't
	implemented yet, the biggest being current working groups
	always acting on the root of the mount tree, and H5Fclose()
	closing the entire tree.  The rest of the stuff will be added
	shortly...

./src/H5P.c
./src/H5Ppublic.h
	Added the H5P_MOUNT property list but haven't implemented any
	particular properties for it yet.

./src/H5Gstab.c
	Hard links across files return an error instead of failing an
	assertion.
