------------------------------------------------------
From: "Luis R. Rodriguez" <mcgrof@xxxxxxxxxx>
Subject: test_sysctl: add simple proc_douintvec() case

Test against a simple proc_douintvec() case. While at it, add
a test against UINT_MAX. Make sure UINT_MAX works, and UINT_MAX+1
will fail and that negative values are not accepted.
