In preparation of Cyrus IMAP 2.5: autoconf and automake

The idea at the end is to create the tarballs with "make dist", which 
includes Makefile.in, config.h.in and configure, so that "autoreconf" 
does not have to be run by the ones downloading the tarball (and it does 
not matter, if git manages those files).

Apart from including the hand-written files, and the files listed by 
automake --help, some more generated files are going to be included by 
"make dist", but I am not sure yet which files exactly.

I guess this has not working also in cyrus-imapd-2.4 .

The problem with -lkrb5 might disappear if you upgrade automake.  On my 
system, automake adds -lkrb5 to LIBS and uses $LIBS when linking (if 
libkrb5 is found during configure).  Which file exactly can't you link?

I have renamed "sun" to "mysun" in imap/(append,idlemsg).c and uploaded 
the changes.
