merges r29493,r29494,r29505 and r29509 from trunk into ruby_1_9_2.

--
* file.c (DEVT2NUM): added. Size of dev_t is depend on the
  environment even if POSIX defines dev_t as unsigned integer.
  For example, OpenVMS, 64bit Solaris 9, and NetBSD 6 defines
  dev_t as 64bit unsigned integer.

* file.c (rb_stat_dev): use DEVT2NUM.

* file.c (rb_stat_dev_major): dev_t is not long. major(3)'s return
  value is int.

* file.c (rb_stat_dev_minor): dev_t is not long. minor(3)'s return
  value is int.

* configure.in: check size of dev_t.
--
Refix for r29493; it is unsigned.
--
* configure.in (dev_t): use RUBY_REPLACE_TYPE.

* file.c (rb_stat_inspect): use PRI_DEVT_PREFIX.
--
* file.c (NUM2DEVT, DEVT2NUM, PRI_DEVT_PREFIX): fallback to
  unsigned int.
