Optimize the vector-vector memcpy() routine even further, for a total

Make a generic vector-vector operation routine and convert other
vector-vector read & write routines to use generic routine instead of multiple

Bug 1707 is that H5Eset_auto causes a seg fault when an application uses -DH5_USE_16_API with
the 1.8 library to compile.
I created a branch off the trunk called set_auto to continue working on the problem.

Description:
The AIX platform does not install the lib*.so for some reason but libhdf5.a
acts like a shared library. Until we can find out how to fix this, patch
up tetlibinfo.sh to not look for an lib*.so in AIX. (Note the test results
look wierd as it says libhdf5.a passed and skipped.)
Tested: NCSA BP for both enable and disable-shared.
Description:
In an AIX 6.1 system, configure --enable-shared could not build a shared
HDF5 library. The problem was because the version of config.guess was too
old to recongnize AIX 6.X and also configure.in had a local fix which did
not recognize AIX 6.X.
Solution:
1. Mike McGreevy updated bin/config.guess to handle AIX 6.X.
2 Albert fixed configure.in to recognize AIX 6.X.
Note that though HDF5 can build shared lib for AIX 6.X systems
but it still could not install the proper library as in AIX 5.X
systems. Also, bin/config.sub should be updated too.
Tested: BP which is the AIX 6.1 system that exposed this problem.
deprecated symbols were disabled. I made a different definition for H5E_auto_op_t when the
deprecated symbols were disabled.
Tested on jam - a simple change.
Description:
Library versions 1.6.3 and earlier contain a bug which causes them to be unable
to perform certain operations on a group if that group's symbol table
information is not cached in the parent group's symbol table. Versions 1.8.0
to 1.8.5 did not cache this information. Modified library to cache this
information.
Tested: jam, amani, heiwa (h5committest)
through H5Eset_auto. I changed the union in the structure H5E_auto_t. Another change is to
make H5Eget_auto fail if H5Eset_auto is called to set the printing function. I'll write a
document for it.
Tested on heiwa, jam, and amani.
The property change in configure.in, config, and Makefile.am came from the merge of the 1.8
library change.

Problem appears to have been caused by file system contention.
In the chunked dataset case, reshaping the chunks so that only one
process would touch each chunk and setting the alignment equal to the
default Lustre block size more or less dealt with the problem.
For contiguous datasets, the problem was a bit more difficult, as
re-working the test to avoid contention would have been very time
consuming.
Instead, I added code to time one execution of each type of shape
same test, and skip additional tests of that type if the duration
of the test exceeded some threshold
In all cases, I set up code to turn off the above fixes if express
test is 0.
Tested on Abe and commit tested. On the commit test, the configure
test failed -- probably because I was h5committest from heiwa due
to some ssh wierdness. In any case a manual reconfigure run on
jam seemed to work fine.
Also, in h5committest, I ran into some data conversion warnings.
I didn't worry about them as the only code I changed was in testpar.

Description:
The fractal heap header structure keeps a pointer to the file associated with
it. However, it is possible for that file pointer to be closed while the
header is still in cache (through the shared file pointer). Previously, the
header's file pointer was not updated and subsequently pointed to an invalid
file structure. Modified fractal heap code to update the file pointer every
time the header is accessed.
