 NAME
    H5O_attr_encode
 PURPOSE
    Encode a simple attribute message
 USAGE
    herr_t H5O_attr_encode(f, raw_size, p, mesg)
        H5F_t *f;         IN: pointer to the HDF5 file struct
        const uint8 *p;         IN: the raw information buffer
        const void *mesg;       IN: Pointer to the simple datatype struct
 RETURNS
    Non-negative on success/Negative on failure
 DESCRIPTION
        This function encodes the native memory form of the attribute
    message in the "raw" disk form.
 *
 * Modifications:
 * 	Robb Matzke, 17 Jul 1998
 *	Added padding for alignment.
 *
 * 	Robb Matzke, 20 Jul 1998
 *	Added a version number at the beginning.
 *
 *	Raymond Lu, 8 April 2004
 *	For data space, changed the operation on H5S_simple_t to
 *	H5S_extent_t

 *              If the H5L_ELINK_PREFIX_NAME property is set in the

 *		Vailin Choi; Sept. 12th, 2008; bug #1247
 *		Retrieve the file access property list identifer that is set

 *		If the return value is H5P_DEFAULT, the parent's file access
 *		property is used to H5F_open() the target file;

/*-------------------------------------------------------------------------
 * Function:    H5C_apply_candidate_list
 *
 * Purpose:     Apply the supplied candidate list.
 *
 *		We used to do this by simply having each process write 
 *		every mpi_size-th entry in the candidate list, starting 
 *		at index mpi_rank, and mark all the others clean.  
 *
 *		However, this can cause unnecessary contention in a file 
 *		system by increasing the number of processes writing to 
 *		adjacent locations in the HDF5 file.
 *
 *		To attempt to minimize this, we now arange matters such 
 *		that each process writes n adjacent entries in the 
 *		candidate list, and marks all others clean.  We must do
 *		this in such a fashion as to guarantee that each entry 
 *		on the candidate list is written by exactly one process, 
 *		and marked clean by all others.  
 *
 *		To do this, first construct a table mapping mpi_rank
 *		to the index of the first entry in the candidate list to
 *		be written by the process of that mpi_rank, and then use
 *		the table to control which entries are written and which
 *		are marked as clean as a function of the mpi_rank.
 *
 *		Note that the table must be identical on all processes, as
 *		all see the same candidate list, mpi_size, and mpi_rank --
 *		the inputs used to construct the table.  
 *
 *		We construct the table as follows.  Let:
 *
 *			n = num_candidates / mpi_size;
 *
 *			m = num_candidates % mpi_size;
 *
 *		Now allocate an array of integers of length mpi_size + 1, 
 *		and call this array candidate_assignment_table. 
 *
 *		Conceptually, if the number of candidates is a multiple
 *		of the mpi_size, we simply pass through the candidate list
 *		and assign n entries to each process to flush, with the 
 *		index of the first entry to flush in the location in 
 *		the candidate_assignment_table indicated by the mpi_rank
 *		of the process.  
 *
 *		In the more common case in which the candidate list isn't 
 *		isn't a multiple of the mpi_size, we pretend it is, and 
 *		give num_candidates % mpi_size processes one extra entry
 *		each to make things work out.
 *
 *		Once the table is constructed, we determine the first and
 *		last entry this process is to flush as follows:
 *
 *	 	first_entry_to_flush = candidate_assignment_table[mpi_rank]
 *
 *		last_entry_to_flush = 
 *			candidate_assignment_table[mpi_rank + 1] - 1;
 *		
 *		With these values determined, we simply scan through the 
 *		candidate list, marking all entries in the range 
 *		[first_entry_to_flush, last_entry_to_flush] for flush,
 *		and all others to be cleaned.
 *
 *		Finally, we scan the LRU from tail to head, flushing 
 *		or marking clean the candidate entries as indicated.
 *		If necessary, we scan the pinned list as well.
 *
 *		Note that this function will fail if any protected or 
 *		clean entries appear on the candidate list.
 *
 *		This function is used in managing sync points, and 
 *		shouldn't be used elsewhere.
 *
 * Return:      Success:        SUCCEED
 *
 *              Failure:        FAIL
 *
 * Programmer:  John Mainzer
 *              3/17/10
 *
 * Changes:     Ported code to detect next entry status changes as the 
 *              the result of a flush from the serial code in the scan of 
 *              the LRU.  Also added code to detect and adapt to the 
 *              removal from the cache of the next entry in the scan of 
 *		the LRU.
 *
 *		Note that at present, all of these changes should not 
 *		be required as the operations on entries as they are 
 *		flushed that can cause these condiditions are not premitted
 *		in the parallel case.  However, Quincey indicates that 
 *		this may change, and thus has requested the modification.
 *
 *		Note the assert(FALSE) in the if statement whose body 
 *		restarts the scan of the LRU.  As the body of the if 
 *		statement should be unreachable, it should never be 
 *		triggered until the constraints on the parallel case 
 *		are relaxed.  Please remove the assertion at that time.
 *
 *		Also added warning on the Pinned Entry List scan, as it
 *		is potentially subject to the same issue.  As there is 
 *		no cognate of this scan in the serial code, I don't have
 *		a fix to port to it.
 *

 * Function:	H5G_namei
 *
 * Purpose:	Translates a name to a symbol table entry.
 *
 *		If the specified name can be fully resolved, then this
 *		function returns the symbol table entry for the named object
 *		through the OBJ_ENT argument. The symbol table entry for the
 *		group containing the named object is returned through the
 *		GRP_ENT argument if it is non-null.  However, if the name
 *		refers to the root object then the GRP_ENT will be
 *		initialized with an undefined object header address.  The
 *		REST argument, if present, will point to the null terminator
 *		of NAME.
 *
 *		If the specified name cannot be fully resolved, then OBJ_ENT
 *		is initialized with the undefined object header address. The
 *		REST argument will point into the NAME argument to the start
 *		of the component that could not be located.  The GRP_ENT will
 *		contain the entry for the symbol table that was being
 *		searched at the time of the failure and will have an
 *		undefined object header address if the search failed at the
 *		root object. For instance, if NAME is `/foo/bar/baz' and the
 *		root directory exists and contains an entry for `foo', and
 *		foo is a group that contains an entry for bar, but bar is not
 *		a group, then the results will be that REST points to `baz',
 *		OBJ_ENT has an undefined object header address, and GRP_ENT
 *		is the symbol table entry for `bar' in `/foo'.
 *
 *		Every file has a root group whose name is `/'.  Components of
 *		a name are separated from one another by one or more slashes
 *		(/).  Slashes at the end of a name are ignored.  If the name
 *		begins with a slash then the search begins at the root group
 *		of the file containing LOC_ENT. Otherwise it begins at
 *		LOC_ENT.  The component `.' is a no-op, but `..' is not
 *		understood by this function (unless it appears as an entry in
 *		the symbol table).
 *
 *		Symbolic links are followed automatically, but if TARGET
 *		includes the H5G_TARGET_SLINK bit and the last component of
 *		the name is a symbolic link then that link is not followed.
 *		The *NLINKS value is decremented each time a link is followed
 *		and link traversal fails if the value would become negative.
 *		If NLINKS is the null pointer then a default value is used.
 *
 *		Mounted files are handled by calling H5F_mountpoint() after
 *		each step of the translation.  If the input argument to that
 *		function is a mount point then the argument shall be replaced
 *		with information about the root group of the mounted file.
 *		But if TARGET includes the H5G_TARGET_MOUNT bit and the last
 *		component of the name is a mount point then H5F_mountpoint()
 *		is not called and information about the mount point itself is
 *		returned.
 *
 * Errors:
 *
 * Return:	Success:	Non-negative if name can be fully resolved.
 *				See above for values of REST, GRP_ENT, and
 *				OBJ_ENT.  NLINKS has been decremented for
 *				each symbolic link that was followed.
 *
 *		Failure:	Negative if the name could not be fully
 *				resolved. See above for values of REST,
 *				GRP_ENT, and OBJ_ENT.

 *      The component name buffer on the stack has been replaced by
 *      a dynamically allocated buffer on the heap in order to
 *      remove limitations on the length of a name component.
 *      There are two reasons that the buffer pointer is global:
 *        (1) We want to be able to reuse the buffer without
 *            allocating and freeing it each time this function is
 *            called.
 *        (2) We need to be able to free it from H5G_term_interface()
 *            when the library terminates.

 *      Added `id to name' support.
 *
 *      Quincey Koziol, 2003-01-06
 *      Added "action" and "ent" parameters to allow different actions when
