Rename imap-send's internal info/warn functions.
Because I am about to introduce a global warn() function (much
like the global error function) this global declaration would
conflict with the one supplied by imap-send. Further since
imap-send's warn function output depends on its Quiet setting
we cannot simply remove its internal definition and use the
forthcoming global one.
So refactor warn() -> imap_warn() and info() -> imap_info()
(the latter was done just to be consistent in naming).
