[svn-r8731] Purpose:

    Code cleanup & minor optimization

Description:
    Re-work the way interface initialization routines are specified in the
library to avoid the overhead of checking for them in routines where there is
no interface initialization routine.  This cleans up warnings with gcc 3.4,
reduces the library binary size a bit (about 2-3%) and should speedup the
library's execution slightly.

Platforms tested:
    FreeBSD 4.10 (sleipnir) w/gcc34
    h5committest
