Bug fixes
Reset external file list slots name_offset to a state when created (0) in H5P_dcrt_copy
so that it conforms to an assertion in H5D_update_entry_info that assumes the name_offset is 0 at this point
this fixes the problem of h5repack and external files, add a new test and files for an external file
h5diff, check for an error return in H5D_get_storage_size

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.

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)
Update the file offsets for files created with "latest version" flag of
h5mkgrp to reflect changes to superblock size.

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

that don't exist in destination file yet.
Add more tests to h5copy script.

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.

Add feature to h5copy to allow it to add an object to an existing file,
instead of blowing away existing file.
Modify h5tools_fopen() routine to take access flags, so it can be used
to open an existing file for writing.
Added check to h5copy test script that verifies it has produced a file
with the correct structure.

Fix core dump for iterating over attributes and not passing in a "starting
point".
Update output files missed in previous checkin. This change essentially
reverses a previous change of attribute ordering, leaving the output of h5dump
& h5ls compatible with 1.6.x

2 tests that were previously incorporated inside the array indices test file were separated from it. These are a test with a dataset with dimensions greater tan 4GB and a test to read by hyperslabs
New version of the function h5tools_dump_simple_subset, to display subsetting. The new algorithm is:
Introduced an outer loop for cases where dimensionality is greater
than 2D. In each iteration a 2D block is displayed by rows in a inner
loop. The remainning slower dimensions above the first 2 are incremented
one at a time in the outer loop
Note: when blocks are introduced, the display is not correct. This is a bug that requires an improvement of the algorithm.
Fixed#720 h5dump: improve how region references are displayed. h5dump now uses the new API function H5Rget_name to display the name of the dataset referenced instead of its ID. Added a case to the script test file
Fix several bugs
1) the parsing of subsetting was using atoi to convert the parameter to an int, which caused problems for numbers greater that int. Substitute with atof
2) the printing of indices in the subsetting case was not being done. Solution: calculate the element position at the start of the subsetting using the algorythm
Given an index I(z,y,x) its position from the beginning of an array of sizes A(size_z, size_y,size_x) is given by
Position of I(z,y,x) = index_z * size_y * size_x
+ index_y * size_x
+ index_x
And pass that position to the function that dumps data, h5tools_dump_simple_data.
3) several index counters were declared as int, use hsize_t instead
4) modified the test generation program so that it includes test cases for subsetting of 1d, 2d, 3d, and 4d arrays and add these tests to the shell script
Cleaned warnings
h5diff_array.c:804: warning: passing arg 1 of `fabs' as floating rather
than integer due to prototype
introduced double precision arithmetic when possible instead of single
precision
Added a relative error formula to deal with floating point uncertainty
in the comparison of floats and double types.
Added new tests for this feature to the file generator program and to
the shell script
