[svn-r9816] Purpose:
cleanup warning messages.

Description:
Compilers complained about local variable shadowed global variables.
The global variables d[], m[], nd, na were having the same names
as local function arguments.  This was a left over when I broke the
original one big chunk of code into separated functions to go around
the Intel Compiler optimization error.

Solution:
Appended the global variables with suffix _g, thus
d[]  =>  d_g[]
m[]  =>  m_g[]
nd   =>  nd_g
na   =>  na_g

This is only an intermediate step.  After the changes tested
out fine by all machines, need to rename the variables to more
meaningful names like dtype_array.

Platforms tested:
Tested in heping by saving the previous generated H5Tinit.c,
regenerated a new H5Tinit.c with the changed code, finally
compared the new and old versions were identical.
