commit 5ed3a02859e91b67b289e7419e9433f50bfb1259

    Make krb5_trace_info a typedef
    
    Our doxygen-to-sphinx documentation bridge only processes typedefs
    and not structure definitions, since we almost universally use
    typedefs for our data structures.  krb5_trace_info is the sole
    exception, so bring it into the fold.
    
    While here, flesh out the comment a bit more.
    
    (cherry picked from commit 6a019d5cff9aecb88591accf03ac737c6f910c69)
