Move JdbcOdbc files to closed.
In the process, the ALT_ODBCDIR and ODBCDIR dependency at build time for Solaris 32bit will be removed, the Makefile will be fixed to use the same Linux fake libraries trick on all Unix platforms, the broken fake library generation issue on some Linux 64bit platforms that require all shared libraries to have all code -fPIC will be fixed, and the missing ODBC library dependency on Solaris 64bit versions of libJdbcOdbc.so will be fixed.

This involves makefiles, readme docs, and moving sources. No actual C/C++/Java sources will change.
