There are more modern tools for memory debugging, get rid of DMALLOC

I've left one reference in backend.c to prevent a merge conflict but
this can be removed later.

Attempt to make the backend handling logic thread-safe. This removes the
last MDB_CONSTRUCTOR. Also get rid of some JAVA junk and make the
remaining static variables in backend.c constant. Finally remove some
obsolete fields from MdbFile.

Also cut MDB_OLE out into its own code path. This removes the last of

Attempt to make the ODBC driver thread-safe
...
I'm not sure if this is a complete solution - some of the global state
has been moved to thread-local storage. So passing an ODBC handle across
threads may have unexpected results. But at least it's not global state.
Each ODBC handle now has its own iconv_t object.
