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.

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.

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.

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.

Bug fix
Some data was declared as char and saved with H5T_NATIVE_CHAR type. But the data have negative values
Solution : declared data as signed char and used H5T_NATIVE_SCHAR
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.

Bug fix: the macro used for percentage in the unsigned types needed a cast to signed (the difference can be negative)
Unlike the 1.6 branch the unsigned long long conversion to float is supported by H5Tconvert , so the test commented for 1.6 is run (tools/testfiles/h5diff_16_2.txt)
Move split between "fixed" and "variable length" portions of superblock
to be immediately after the superblock version number.
Minor cleanups in h5debug's handling of superblock signature.

Description: Multiple copies of Copyright appeared in Makefile.in. This was
due to automake copying the copyright right in the included files such as
config/commence.am.
Solution: Automake treats double hashes as comments and does not copy them
to Makefile.in. Changed all the copyright notices in config/*.am to use
double hashes for the Copyright right notice.
Tested: kagiso via bin/reconfigure.
Mask off the storage utilization for the h5ls output, so that the
h5ls output is more portable (VL datatype size is reported as the memory size
instead of the file size, making the storage utilization incorrect - entered
in bugzilla)

Put paths to testfile input & output directories in one place, making it
easier to modify them if we choose to re-arrange our testfile locations in
the future (this should probably be carried over to other test scripts).
Make h5copy exit more cleanly if no command line parameters are given.

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).

Too minor to require more tests
Refactor h5copy testing script to abstract out some of the common behavior,
obey the "HDF5_NOCLEANUP" environment variable, delete any output file left
over from a previous run, add a "test variation" parameter to output file name
for adding next sequence of test variations, etc.
