Enable tools lib to be built as a dll on windows. Added two get/set functions for progname and d_status.
Also add windows import/export declarations to functions.
Updated error_mesg() and warn_mesg() to remove progname argument and use get functions
Tested:
Windows, linux
Unify srcdir handling for test executables and allow them to use the srcdir
setting from configure time without requiring the 'srcdir' environment variable
be set (although you still can, to override the built in setting). Attempted
to get this right for Windows builds also.
Also add dependency between src/H5Tinit.c and src/libhdf5.settings, so
that the test/testcheck_version.sh script works correctly.
Tested on:
Linux/32 2.6 (jam)
Mac OS X/32 10.6.2 (amazon)
