    syslogd: Increase message size limits

    Add a -M option to control the maximum length of forwarded messages.
    syslogd(8) used to truncate forwarded messages to 1024 bytes, but after
    commit 1a874a126a54 ("Add RFC 5424 syslog message output to syslogd.")
    applies a more conservative limit of 480 bytes for IPv4 per RFC 5426
    section 3.2.  Restore the old default behaviour of truncating to 1024
    bytes.  RFC 5424 specifies no upper limit on the length of forwarded
    messages, while for RFC 3164 the limit is 1024 bytes.

    Increase MAXLINE to 8192 bytes to correspond to commit 672ef817a192.

    Replaced bootfile[] size for MAXPATHLEN used in getbootfile(3) as a
    returned value. Using (MAXLINE+1) as a size for bootfile[] is excessive.
