The Togg's sysklogd patch to use sendto() on remote logging is formatting
strangely (using `<' and '>' surrounding the `msg' string message).  This
is OK, but this is not the standard way of formatting this message.

So this patch does the following:

o Fix the formatting to the standard way.
o Uses `MAXLINE' when needed;
o Don't loop sending messages without a "sleeping time",
  I'm now doing `now = 1', `now <<= 1';
o Don't die on `init_RemoteLog' when starting up (feature!)
  We're now trying to connect every time we have an invalid fd;
o Removes one static uneeded variable.
o Removes two automatic uneeded variables.
