macro didn't work on all systems. This fixes it.
This also introduces the ability to configure for fortran and c++. This
is not to be implemented yet, though!
multi-dereferenced pointer chains. This buys us another ~20% improvement in
the hyperslab I/O speed. (From ~30 seconds to ~25 seconds on the h5hypers
benchmark)
Bug fixes
Description:
All tests were core=dumping in IRIX64. The bug is in Generic
property list creation in which malloc asked for 2*64-1 bytes
due to coding bug. The object creation failed but the return
code was not checked. Program eventually crashed.
Solution:
H5F.c:
Check the return code from new file object creation and flag
error accordingly.
H5FL.c:
H5FL_arr_free is a replacement for H5MM_xfree which accepts
null value as a legal argument value. H5FL_arr_free assert
on it. Since other parts of the code have been passing null
value to H5MM_xfree, H5FL_arr_free must accept it too until
all the calling routines are changed to not pass Null.
H5P.c:
some routine passes in 0 as the hashsize value which is uintn.
The expression (hashsize-1) underflows to the largest unsigned
int for some machines. Thus the calloc failed. Cast hashsize
to unsigned int first (this assumes hashsize stays within the
signed int data range.
H5Smpio.c:
Added the extra parameter because the H5FD_write has been redefined.
Platforms tested:
IRIX64 -64 and -n32
applied for various platforms which weren't supported by libtools are now
standard for libtools it seems. There were only a few of the previous
fixes I rolled forward (the diffs follow):

hyperslab boundaries after adding them all, instead of maintaining the sorted
order during each addition. This boosts performance for sub-sampled (i.e.
strided) hyperslabs by about a factor of 10! :-)
added code to allow metadata to be allocated out of a more contiguous block
("metadata aggregation") and also code for "catching" small metadata write
calls and building a buffer of the small pieces of metadata for later writing
as one, larger, block ("metadata accumulation"). These features are enabled
on a per VFL driver basis with the new VFL 'query' call and both currently
enabled for the sec2, family and stdio drivers. The mpio VFL driver enables
only the "metadata aggregation" code, not the "metadata accumulation" code.
All the other drivers have these features turned off.
