[svn-r17058] added some "dummy" declarations for d_status

this error
home/hdftest/snapshots-hdf5/current/tools/lib/h5tools_ref.c:126: undefined reference to `d_status'

happens because the original developer of h5tools_ref.c declared these 2 variables in that source file

extern char   *progname;
extern int    d_status;

this means that all programs that use this source file (typically all tools) will have to define these 2 variables, even if they are *not* used. 

examples

const char *progname = "h5jam";
int d_status = EXIT_SUCCESS;

"progname" is usually used to print the program name in the usage, and "d_status" is just a return value of the tool, usually.

I was wondering about removing these 2 declarations from h5tools_ref.c

extern char   *progname;
extern int    d_status;

and define those variables on each tool if they are only needed (it seems to me that only h5ls and h5dump actually "need" them)

tested: smirom parallel
