[svn-r10534] Purpose:

Configuration feature

Description:
Different Fortran compilers mangle function names in different ways
(upper case, lower case, adding underscores).  To link between
Fortran and C functions, we need to know what a given function's
name is under a given compiler.

Solution:
Use autoconf's FC_WRAPPERS check to determine the Fortran
naming scheme and define the FC_FUNC_ macro to name our
functions (in H5f90proto.h).  Removed references to
our old FNAME macro, as well as flags that indicated whether
function names were upper or lower case.

Platforms tested:
mir, pommier, modi4, copper, more
