Import qdbm from pkgsrc-wip.  Packaged by OBATA Akio.

QDBM is an embeded database library compatible with GDBM and NDBM.  It
features hash database and B+ tree database and is developed referring
to GDBM for the purpose of the following three points: higher
processing speed, smaller size of a database file, and simpler API.
This package includes APIs for C, C++, and Java.  CGI scripts are also
contained.  APIs for Perl and Ruby should be installed with a source
package.
