90ee7bfcb5 Remove references to dmalloc 
There are more modern tools for memory debugging, get rid of DMALLOC
crap in the source code.

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

452cd29343 Get rid of more static memory 
* Replace backend_is_init (formerly is_init) with relationships_table

* Remove deprecated functions that used static variables

* Move static "bound" variable to MdbHandle as relationships_values

588663675e Move backend dictionary and state to MdbHandle 
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.

673c7700b9 Store OLE strings on the statement object 
Also cut MDB_OLE out into its own code path. This removes the last of
the global / thread-local storage in the ODBC driver, I think.

55e0d4ff07 Store sqlState separtely on ODBC env / handle / stmts

of the actual SQL state.

9020ca9a1e 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.

See #23

dfd41f2283 Try fixing unixODBC deadlock with -Bsymbolic-functions 
This flag compels the dynamic library to prefer its own function symbols
to those in the global symbol table. This behavior should let us
directly call SQL* functions from inside other SQL* functions without
fear of interference by the host program.
