merge revision(s) 33959,33963,34265:
* ext/dbm/extconf.rb: detect gdbm_version in libgdbm.
* ext/dbm/dbm.c: make DBM::VERSION more informative for gdbm, qdbm and
Berkeley DB 1.x. [ruby-dev:44944]
* ext/dbm/dbm.c: use db_version() instead of DB_VERSION_STRING to
detect runtime Berkeley DB version.
use dpversion instead of _QDBM_VERSION to detect runtime QDBM
version.
[ruby-dev:44948]
* ext/dbm/dbm.c (Init_dbm): fix a build error on mswin32.
use `extern __declspec(dllimport)` for dll link with VC.
