commit 6193770ee1f6771758a653730e7a1ecaf2cf9dc8
Author: Dániel Bakai <address@hidden>
AuthorDate: Mon Apr 3 09:16:21 2017 +0200

    tests: added test for Curl_splaygetbest to unit1309
    
    This checks the new behavior of Curl_splaygetbest, so that the smallest
    node not larger than the key is removed, and FIFO behavior is kept even
    when there are multiple nodes with the same key.
    
    Closes #1358
