Merge pull request #24 from evanmiller/odbc-thread-safety 
Make the ODBC driver thread-safe. Multiple simultaneous handles should work fine now, but individual handles should only be used by one thread at at time.

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 
Also fix the fact that "08001" was always returned by SQLError instead
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

ec8492f1ee Try fixing Travis and Appveyor 
The new re-entrant parser requires Bison 3, which is not installed
on macOS by default. It also appears to require -Wno-yacc.

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.
