    resolv: Fix ABA race in /etc/resolv.conf change detection [BZ #25420]
    
    __resolv_conf_get_current should only record the initial file
    change data if after verifying that file just read matches the
    original measurement.  Fixes commit aef16cc8a4c670036d45590877
    ("resolv: Automatically reload a changed /etc/resolv.conf file
    [BZ #984]").

    resolv: Enhance __resolv_conf_load to capture file change data
    
    The data is captured after reading the file.  This allows callers
    to check the change data against an earlier measurement.

    resolv: Fix file handle leak in __resolv_conf_load [BZ #25429]
    
    res_vinit_1 did not close the stream on errors, only on success.
    This change moves closing the stream to __resolv_conf_load, for both
    the success and error cases.
    
    Fixes commit 89f187a40fc0ad4e22838526bfe34d73f758b776 ("resolv: Use
    getline for configuration file reading in res_vinit_1") and commit
    3f853f22c87f0b671c0366eb290919719fa56c0e ("resolv: Lift domain search
    list limits [BZ #19569] [BZ #21475]"), where memory allocation was
    introduced into res_vinit_1.

    Only minor functional changes (i.e., regarding the handling of
    directories, which are now treated as empty files).
