[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
