Changed the error check string to match the function being called, changed the string H5Sselect_all to H5Sselect_none

|

Correct the prototype for H5Sselect_elements() to take an 'hsize_t *' for
the coordinates, instead of 'hsize_t **'.

- Avoid trying to update 1-D dataset's chunk indices (they can't change)
- Cache a copy of a dataspace describing a chunk, when doing single
element I/O
- Keep a 'chunk info' struct around, for single element I/O
- Avoid creating a skip list for chunk infos when performing I/O on single
element
Also, minor formatting cleanups to testing code

- Changed H5S_select_shape_same routine to handle scalar dataspace
comparisons correctly. (Added regression tests to verify)
- Simplified chunk map creation, now that scalar dataspaces are handled
in same way as "simple" dataspaces.

Bug fix/Feature
Description:
Modify the library to use rand_r, when available, instead of srand. If
rand_r is not available, it will try to use srandom/random, and then finally
fall back to srand/rand.
Solution:
A couple places in the library use the srand() function to seed the random
number generator. This can cause problems on certain platforms and could theoretically
cause problems for users who expect a certain sequence of random numbers following their
own call to srand().
Most platforms have an implementation of rand_r, which is identical to rand, except that
it allows for explicit storage of the seed value. The configure script will now check
for the existence of rand_r to facilitate its use in the library.
Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and
HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither
of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call
srandom if available, and fall back to srand otherwise.
Platforms tested:
heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine
is currently not available.

Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

New feature/enhancement
Description:
Chunked datasets are handled poorly in several circumstances involving
certain selections and chunks that are too large for the chunk cache and/or
chunks with filters, causing the chunk to be read from disk multiple times.
Solution:
Rearrange raw data I/O infrastructure to handle chunked datasets in a much
more friendly way by creating a selection in memory and on disk for each chunk
in a chunked dataset and performing all of the I/O on that chunk at one time.
There are still some scalability (the current code attempts to
create a selection for all the chunks in the dataset, instead of just the
chunks that are accessed, requiring portions of the istore.c and fillval.c
tests to be commented out) and performance issues, but checking this in will
allow the changes to be tested by a much wider audience while I address the
remaining issues.

Bug Fix & Feature
Description:
The selection offset was being ignored for optimized hyperslab selection
I/O operations.
Additionally, I've found that the restrictions on optimized selection
I/O operations were too strict and found a way to allow more hyperslabs
to use the optimized I/O routines.
Solution:
Incorporate the selection offset into the selection location when performing
optimized I/O operations.
Allow optimized I/O on any single hyperslab selection and also allow
hyperslab operations on chunked datasets.

Bug Fix
Description:
Regression test for following bug:
When reading a contiguous hyperslab that spanned the entire dataset and
was larger that the type conversion buffer, the hyperslab routines need
to fill the type conversion buffer and then return to the I/O routines.
When the I/O routines resume the hyperslab operation, it was possible to
have a combination of coordinates which caused the hyperslab iterator
to incorrectly advance in the file, causing some data to be re-read or
re-written.

Bug fix & feature add
Description:
Added new API function H5Sget_select_type to determine type of selection in
a dataspace. Return values are defined by the H5S_sel_type enumerated type
in H5Spublic.h
Also, hyperslab operations involving a "all" or "none" selection are not
generating the correct resulting selections.
Solution:
Added regression tests to verify correction operation of hyperslab
operations against "all" and "none" selections. New tests also verify
H5Sget_select_type() API call.

Bug Fix
Description:
The code in H5Sselect_hyperslab_valid contained an fencepost error and is
allowing selections which overlap the extent by exactly one element in any
dimension to pass as valid instead of flagging the selection as invalid.
This bug only affects hyperslabs which have been OR'ed together, not the
selection from a single H5Sselect_hyperslab.
This fixes bug #550.
Solution:
Changed an '>' to an '>=' and added new regression test to check for error.

Code cleanup
Description:
Windows is generating hundreds of warnings from some of the practices in
the library. Mostly, they are because size_t is 32-bit and hsize_t is
64-bit on Windows and we were carelessly casting the larger values down to
the smaller ones without checking for overflow.
Also, some other small code cleanups,etc.
Solution:
Re-worked some algorithms to eliminate the casts and also added more
overflow checking for assignments and function parameters which needed
casts.
