Description: removed the temporary patch of
RUNSERIAL=${RUNSERIAL="env LDR_CNTRL=MAXDATA=0x20000000@DSA"}
and similaryly for RUNPARALLEL since the h5repack test failure
was fixed and this patch is no longer needed. (IBM also advices
not to hardset MAXDATA if possible.)
Tested: NASA G-ADA AIX machine, both 32 and 64 bits modes.
(No parallel test because not able to build or run MPI executables yet.)
Note that this differs slightly from the trunk code since the VFL API won't be
changed until 1.10. In the 1.8 branch, the term() function is public and this
required some #defines for the Windows VFD.
21501:
- Propagated Windows VFD tweaks to SEC2 and log VFDs.
- Created typedefs and #defines to make POSIX I/O type-safe on Windows and true POSIX platforms.
- Added pre-checks and removed post-checks for POSIX I/O sizes. When the number of bytes to be sent exceeds the maximum return value, the operation is split into smaller subsets.
- General code tidying and cleanup.
21502:
- Removed Windows VFD code. H5Pset_fapl_windows() actually sets the SEC2 driver, though it will still report H5FD_WINDOWS.

Purpose:
Remove H5_MPI_SPECIAL_COLLECTIVE_IO_WORKS and
H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS #defines from source.
Description:
Two advanced parallel functionalities, special collective IO and
complex derived datatypes, are not supported by older
implementations of mpi, and thus our code limits the use of these
features with #ifdefs and has checks in configure to set them (or
not). Unfortunately, configure can't actually run a parallel check
to see if these features are working (nor not) so it resorts to
looking in the config files where they are explicity enabled or
disabled based on versions of mpi, sytems being built on, or for
no documented reason at all (i.e. just set to on or off as some
'default'). Overriding these settings is easy if need be, provided
it is known that it needs to be done to get improved performance,
and oftentimes it is not.
Most new MPI implementations successfully handle the functionality
requested when these #defines are set, and many of the "turn these
features off" cases in the config files are for old (> 5 years)
versions of MPI and retired systems (such as NCSA's tungsten).
Therefore, the decision has been made to remove the support for
these old versions of MPI and systems that cannot handle these
behaviors. The #ifdefs and supporting setup in the config/ files
and configure script has been removed, and the code executed when
these options were not set removed from the source.
In passing, this commit also cleans up some whitespace issues in
both t_mpi.c and H5Dmpio.c. Furthermore, in t_mpi.c, the special
collective IO test was not getting regularly run due to it being
written to work only with four processes (we regularly test with
six, previously with three), and thus it failed when actually run
due to an out of bounds data buffer assignment. It has been
modified to run at any number of processes greater than four, and
the memory problem has been fixed so the test passes.

Bring r20538 & r20539 from trunk to 1.8 branch:
Update with new warning flags for gcc 4.6.x
Bring Coverity changes back to trunk:
r20276:
Add recursive is vlen string function.
Cleanup resource leaks for issues: 200,202,329,688,811,812
r20277:
Check types and close by adding error section: issue 687
r20278:
Replaced implicit pointer conversion with (ocrt_info.new_obj != NULL).
r20280:
Addressed coverity issues 927-929 & 583. The real issue is failure to check
file name length -- at least at the H5FD interface level. This needs more work, but at least I have dealt with the issue in H5FDfamily.c
r20337:
H5O_type_t obj_type = H5O_TYPE_UNKNOWN;
r20338:
Added udata.name = NULL; to prevent potential uninitialized use after done: label.
