Patch is mostly created by script in egroupware/doc/fix_depricated.php in separate commit.
I do NOT advice to apply this patch to a production system (it's commited to trunk!), as the automatic modified regular expressions have a good change to break something ...
- cleaned up exceptions in cli code (no need to log, as it goes direct to the user)
- regarding small rpm redirect header (< 200 bytes) as no header
- fixed wrong detected vars for cli install (eg. webserver_url)
- fixed egw_cache to not stall if system_charset is not yet in db
