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.

3c6c8e07db Make mdb-count case-insensitive to table names 
This matches the behavior of mdb-export. Thanks to Nicholas Crookston.

8202e38155 Don't automatically add terminators when reading data parts 
via SQLGetData for OLE fields

if the column type is OLE, then we don't add terminators
see https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/sqlgetdata-function?view=sql-server-ver15
and https://www.ibm.com/support/knowledgecenter/SSEPEK_11.0.0/odbc/src/tpc/db2z_fngetdata.html

"The buffer that the rgbValue argument specifies contains nul-terminated values, unless you retrieve
binary data, or the SQL data type of the column is graphic (DBCS) and the C buffer type is SQL_C_CHAR."
