[PATCH v8 03/12] Move lower case functions into wrapper.c

[Christian Couder <chriscool@tuxfamily.org>]

The lowercase() function from config.c and the xstrdup_tolower()
function from daemon.c can benefit from being moved to the same
place because this way the latter can use the former.

Also let's make them available globally so we can use them from
other places like trailer.c.
