+ * libinterimap: in tunnel mode, use a socketpair rather than two pipes

: One of `imap`, `imaps` or `tunnel`.
`type=imap` and `type=imaps` are respectively used for IMAP and IMAP
over SSL/TLS connections over a INET socket.
- `type=tunnel` causes `interimap` to open a pipe to a *command*
- instead of a raw socket.
+ `type=tunnel` causes `interimap` to create an unnamed pair of
+ connected sockets for interprocess communication with a *command*
+ instead of a opening a network socket.
Note that specifying `type=tunnel` in the `[remote]` section makes
the default *database* to be `localhost.db`.
(Default: `imaps`.)
