* kp/odbc-oracle-autocommit-fix/OTP-10735:
  Fix aotocommit for Oracle ODBC driver in Linux.

With silent rules, the output of make is less verbose and compilation
warnings are easier to spot. Silent rules are disabled by default and
can be disabled or enabled at will by make V=0 and make V=1.

Issue: Oracle ODBC driver for Linux ignores setup autocommit mode during driver initialization before a connection to database has been established. Whereas odbc module in erlang sets autocommit mode before a connection has been established and autocommit mode is true by default it is impossible to turn out autocommit mode for oracle connections.

Sulution: This patch sets autocommit mode after a connection to database has been established. The patch changes only C source file odbcserver.c and don't change any erlang source files of odbc module.

This patch adds the extended_errors option to odbc:connect/2. When
enabled, this option alters the return code of ODBC operations that
produce errors to include the ODBC error code as well as the native
error code, in addition to the ODBC reason field which is returned by
default. The extended error information can be used to produce more
sophisticated error handling than is possible with the standard ODBC
Reason alone.
