Add H5Lvisit_by_name() API routine to library.
Eliminated all (five!) other group traversal routines and changed them
all to use the new API routine.
Cleaned up output of h5ls & h5stat:
- Issue error when requesting recursive traversal of a file
with the "group info" flag, but no group given
- Print info about root group in all(?) appropriate situations
- Don't print "verbose" information about root group until the
root group is in the list of objects to display
(mostly because h5ls & h5stat had a different twist on traversing the
groups in a file that the other utilities)

Change H5[D|G|T]<foo>_expand() "temporary" API routines to
H5[D|G|T]<foo>2() "versioned" routines. Also added
H5[D|G|T](create|commit)_anon() routines to continue to allow "anonymous"
objects to be created in a file.

Eliminate storing # of links in "link info" message, regenerate it
when the object is opened instead.

Move ref. count of # of links to an object out of the object header's
prefix and make it a header message instead (since it's a "rare" occurence),
eliminating some more space for each object in the file.
Inserting this "ref. count" message exposed a flaw in the library's
mechanism for locating a message to promote to another chunk and replace
with a continuation message, which required some additional work to fix.
It's still not completely robust, but it's working for more cases now and
detects failures robustly.
Reduced the minimum size of an object header chunk to just enough to
contain a header message prefix and continuation message.
Tested on:
FreeBSD/32 6.2 (duty)
Move "creation order tracked" flag from "group info" to "link info"
object header message and make the "max. creation order value" optional in the
"link info", if the creation order for links is not tracked.
Also, get rid of unused "index names" flag - names are always indexed
currently.

FreeBSD/32 6.2 (duty)
Eliminate message count from new version of object header prefix -
it can be computed when the header is loaded and the table of messages is
built.
Tested on:
FreeBSD/32 6.2 (duty)
Move attribute tracking information out of object header prefix and
make it into a message that is inserted only when attributes are present on
the object.

FreeBSD/32 6.2 (duty)
The main purpose of this checkin was to eliminate the
space used for tracking creation time indices when there is no way they
can be used (i.e. attributes can't be shared in the file and the user hasn't
turned on attribute creation tracking), however there were some other minor
changes which crept in:
- Fix a cache locking deadlock when a shared attribute and one of its
components end up in the same fractal heap direct block.
(This is fixed the "slow" way for right now, until John has time
to add support for readers/writer locking to the cache.
- Optimize attribute copying when a copy will be kept during a v2 B-tree
search.
- When freeing a block on disk, attempt to merge it with the metadata
and "small data" aggregators.

Revise latest form of superblock format pretty drastically, to
eliminate unused fields and move rarely used fields into superblock extension.
Finished removing last vestiges of references to (never used) i"shared"
object header message ID.
Added object header messages for non-default v1 B-tree 'K' values
and for driver info.
Updated testfiles to reflect size changes, etc.
Various minor cleanups, etc.

Update the file offsets for files created with "latest version" flag of

Add small 'h5mkgrp' tool to create groups in an HDF5 file from the command
line, allowing the group structure for a file to be created in a script. This
tool closely follows the 'mkdir' command line tool in UNIX/Linux.
Allow tool library applications to pass a FAPL to the h5tool_fopen() call,
giving some additional flexibility to tools which are adding objects to an
existing HDF5 file (like h5copy & h5mkgrp).
Fix missing files in MANIFEST from previous checkin(s).
