Bug fix
Description:
dumper repeated output after the 1st 4 rows.
The bug was because the dumper was reading just a small slice a time
from the file dataset but did not adjust the offset in the file-space.
So, it just kept reading the same first slice.
Solution:
Stole the offset-adjustion code from the routine that h5ls uses.
Platform Tested:
O2K.

Finally fixed a long-standing bug that caused core dumps if
a compound datum rendered to more than some number of
characters (we kept bumping up the limit at the risk of
violating stack size limits on some machines). The fix works
only on systems that have the vsnprintf() function (otherwise
a 4kB limit is imposed, which if violated probably dumps
core). If vsnprintf() is present then the library dynamically
allocates space for the output string.
Also made it possible to control how compound data is rendered
across multiple lines of output by allowing the caller to
specify where optional line-breaks get inserted. The output
functions split up the value at one or more optional
line-breaks to prevent it from wrapping around the screen.
If a datum doesn't fit on the current line but would fit on
the next line then it is printed on the next line regardless
of whether optional line-breaks would have prevent wrapping
around the screen. This makes it easier to find the beginnings
of compound data values. This feature is disabled by default
but can be enabled by the application.
If a datum doesn't fit on the current line and the previous
datum also occupied more than one line then we move to the
next line before printing. This makes it easier to find the
beginnings of compound data values but prevents the output
from looking fragmented if there are only a few long values
among mostly short values. This feature is disabled by
default but can be enabled by the application.
The application can control the printf() formats used for all
the native data types. The defaults are what the library used
to use: %g, %ld, %lu, %d, and %u
./tools/h5ls.c
Compound datatype values can now be split across multiple
lines of output instead of just wrapping. Also, when lots of
compound values are too long they all start at the beginning
of a line. This only required about 10 lines of changes in the
setup for tools library calls (I didn't modify the h5dump
program because it uses its own version of the tools library
that forked off long ago).
Added code for Win32 which is unable to cast `unsigned long
long' to `double'. If the dataset size exceeds (2^63)-1 then
the percent utilization is not displayed (this is easily
possible with chunked datasets). This is untested yet.

Check for vsnprintf() and provide a simple, stupid definition
if it isn't available. The stupid definition just calls
vsprintf() and ignores the second argument. This can result in
buffer overflows in h5ls and h5dump since vsprintf() is an
unsafe function (and anyone can create an hdf5 file that runs
an arbitrary command from h5ls and h5dump in that case)!

Cleaned up a memory leak during H5_term_library() by allowing
H5I_clear_group() to skip items that couldn't be freed. This
allows the item to remain in the group until we can free it
later.

The H5F_close_all() function fails if a file cannot be closed.

Fixed a call to H5F_block_read() since the 4th argument is

Added a space between the object name and class to make the

Changed H5F_block_read/write() to take a file transfer
property list instead of just a parallel I/O mode. This will
allow us to pass additional parameters to the I/O functions
without having so many arguments to worry about.
This fixes a bug I introduced last Friday for parallel HDF5
./src/H5B.c
Fixed decoding of B-tree keys when iterating through the
leaves of the B-tree. This fixes a bug for applications that are
adding new entries to groups and also listing the groups.
to "H5D_transfer_t xfer_mode". H5F_mpio_write/read are i/o driver
calls as low as H5F_low_write. This class of functions are invoked
with the xfer_mode argument.
H5Dread/H5Dwrite to use to allow the I/O calls to break up a user's buffer into
pieces that are at least as large as the sequence of bytes being written in the
fastest changing dimension.
Also fixed a hard-to-find bug in the hyperslab I/O routines which could cause
data to be corrupted when writing out fields to compound datatype data with
background preservation turned on and hyperslabs which were large enough to
require two I/O passes on a hyperslab block. A pretty obscure situation, but
it would be worthwhile for users to upgrade to this code in order to be certain
that correct data is being written.

Fixed automatic dependencies. We were storing dependencies for
*.o files instead of *.lo files after shared libraries were
added.
./config/gnu-flags
./config/linux-gnulibc1
Moved `-march=pentiumpro -mcpu=pentiumpro -malign-double' from
the linux file to this file and caused it to depend on the CPU

Added an H5Dget_storage_size() function that reports the
amount of storage allocated for raw data in a dataset.
Changed H5D_xfer_* to H5F_xfer_* because these properties are
more general than datasets. This also allows some of the
lower-level I/O functions to get this information easier.
./src/H5S.c
./src/H5Sall.c
Added two new functions H5S_all_read() and H5S_all_write()
which are optimizations that copy data directly between file
and memory without having to go through the scatter gather
step. This knocks quite a bit of time off the I/O and
reading/writing entire datasets is a fairly common operation.
./tools/h5ls.c
Reports the logical size of data, the allocated size of data,
and the percent utilization.
./MANIFEST
Removed old pablo files, added new files. Snapshots should now
start to work again.
