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.
Kent did most of the work, I just went over his changes and fit them into
the the library code a bit better.

Bug fix.
Description:
The internal B-tree code was dumping core with an assertion failure when

2. move H5_inline defination for win32 to windows H5pubconf.h at H5private.h.
Description:
1. the mtime test is not working when the daylight saving ends. Hard-coded back to the correct time. Need to find a universal solution later.
2. Move H5_inline defination for win32 at H5private.h into windows specificed H5pubconf.h so that windows maintenance can be more easy to handle.
Solution:
see above.

Bug fix/optimization.
Description:
Single, contiguous (in memory) hyperslabs are able to be transferred in one
I/O operation, but weren't being detected correctly by the code in
H5S_all_read()/H5S_all_write() and were getting routed into slower I/O
routines. (Or, possibly failing in some circumstances)
Solution:
Wrote code to correctly detect single contiguous hyperslabs in memory and
adjust arrays and buffer pointers describing the memory information so that
the entire hyperslab can be transferred in one operation.

Bug fix.
Problem:
When an entire dataset was selected (through whatever means, H5S_ALL, making
an explicit "all" selection, etc.), the code was not allowing the optimized
routine to read the entire dataset in at once when the current dimensions
did not match the maximum dimensions and instead was defaulting to a [much]
slower method to read in the dataset.
Solution:
Took out check which was requiring current dimensions to be equal to the
maximum dimensions.

Bug Fix
Description:
When writing (or reading) the entire dataset to a chunked dataset, there
was a boundary case where the code to generate the description of the
piece of the dataset to read into the buffer for data conversion would
attempt to read off the boundary of the dataset. This was occuring because
the code to detect the edge of the dataset was not propagating the change
up through the remaining dimensions when an edge in a fast changing
dimension was detected.
Solution:
Propagate edge detection up through slower changing dimensions properly.

Kludge
Description:
Since we're only about halfway through converting the internal use of
property lists from the "old way" to the generic property lists, we turned
off snapshots to avoid exposing lots of API changes to users, until the
APIs settled down.
Getting the snapshots rolling again seems to have become a priority, so
some changes are going to have to be made now that were going to be
postponed until we were completely finished with the conversion. This
requires that the old API functions be able to deal with both the old
and new property lists smoothly.
Solution:
Kludge together the property list code so that they can transparently handle
dealing with both the old and new property lists
