[svn-r8136] Purpose:
Optimization
Description:
Speed up various parts of the library by setting a global variable for the
endianness of the machine at library startup and use that variable instead of
repeatedly querying the endianness of the native int datatype.
Platforms tested:
IBM p690 (copper)
too minor to require h5committest
