    crashinfo: Create core.txt.last symlink
    
    When saving a coredump, savecore(8) maintains .last symlinks for the
    info and vmcore artifacts, but not for the crashinfo text report.
    
    Make crashinfo(8) create the link, pointing at the current
    core.txt.<bounds> file.
    
    This makes /var/crash/core.txt.last track the same core dump as
    info.last and vmcore.last.
    
    [mhorne: I tweaked the submission, such that the link will be created as
    soon as the core.txt.X file is generated; not only after a successful
    report has been written.]
