[svn-r17] ./src/H5AC.c

	Renamed H5AC_find() to H5AC_find_f() which is invoked from the
	H5AC_find() macro.

	Changed HASH() to H5AC_HASH().

./src/H5ACprivate.h
	Increased the number of cache slots from 1033 to 10330 to see
	how it affects performance.  This should probably be
	changeable on a per-file basis.

./src/H5B.c
	Fixed some bugs now that symbol tables are actually using the
	stuff.

	Improved debugging a little.

	Fixed uninitialized memory appearing in the file.

./src/H5D.c
	Changed a FUNC_ENTER() argument from H5Dset_info to H5Dwrite.

./src/H5F.c
	Plugged a memory leak in H5F_dest().

./src/H5G.c
./src/H5Gprivate.h
	Many of these functions take a symbol table entry which
	describes the symbol table rather than just the symbol table
	address.

	Moved some functions to make room for the ones that understand
	directory names:
		  H5G_new()	-> H5G_stab_new()
		  H5G_find()	-> H5G_stab_find()
		  H5G_modify()	-> H5G_stab_modify()
		  H5G_insert()	-> H5G_stab_insert()
		  H5G_list()	-> H5G_stab_list()

./src/H5Gnode.c
	Added more assertions.

	Zero new memory so junk doesn't appear in the data file.  This
	is a problem when one tries to declassify a classified data
	file.

	H5G_node_debug() can take an extra argument which is the
	address of the heap for the symbol table.  If supplied, the
	symbol names are printed along with the heap offsets.

./src/H5H.c
./src/H5Hprivate.h
	Fixed a bug with the free blocks by forcing things to align on
	even boundaries.  It's still possible to lose heap memory if
	the hole is smaller than the free list header.  The
	alternative is to align heap objects on 12 or 20 byte
	boundaries, but this tends to waste to much space.

	Zero new memory like with H5Gnode.c.

	Fixed a "mispeling" of NDEBUG.

./src/H5Ocont.c
./src/H5Onull.c
	Added the pablo mask defn.

./src/H5Ostab.c
	Added the pablo mask defn.

	Fixed a read from uninitialized memory.

./src/H5Oprivate.h
	Tuned some parameters to see how they affect performance.

./src/debug.c
	An optional third argument can be supplied which is the
	address of a heap to use to display names in a symbol table.

./src/hdf5pabl.h
	Changed `int' to `intn'.
