* mail-source.el: Require imap when compiling and defvar
display-time-mail-function. Require mm-util.
(nnheader-cancel-timer): Autoload.
(mail-source-imap-authenticators, mail-source-imap-streams): New
variables.
(mail-sources): Use them.
(defvar): Use rmail-spool-directory unconditionally.

* mail-source.el (mail-sources): Better `:type'.

* mail-source.el (mail-source-keyword-map): Use
`rmail-spool-directory' as a default directory for the `file'
source, if the variable is defined. Fall back to hardcoded
"/usr/spool/mail/", as before. Suggestion by Steven E. Harris
<seh@speakeasy.org>.
