Make _fetch_connect() always set the error code.
Tell ftp that _fetch_connect() always sets the error code (http already knew)

Cope with 2292bis-01 getaddrinfo (no NI_WITHSCOPEID, always attach
scope identifier).

Add a reference count to struct fetchconn so we don't prematurely close and
free a cached FTP connection.

Wrap everything in struct connection, and enforce timeouts everywhere
(except for DNS operations). Always use funopen() for HTTP, to support
both timeouts and SSL.

First step towards SSL support: wrap connections in a 'struct connection'
which contains the socket descriptor, the input buffer and (yet unused)
SSL state variables. This has the neat side effect o

First step towards SSL support: wrap connections in a 'struct connection'
which contains the socket descriptor, the input buffer and (yet unused)
SSL state variables. This has the neat side effect of greatly improving
reentrance (though we're not *quite* there yet) and opening the door to
HTTP connection caching.

Henry Whincup <henry@techiebod.com> last fall.

Don't call _ftp_closefn() upon EOF in _ftp_readfn(); just return 0. This
fixes a bug in pkg_add(1) (which nobody noticed because of another bug).

Add rudimentary support for an authentication callback function.

Apply 'const' liberally.

Fix some other minor glitches.

If the server's reply to the SIZE command is unparseable, reset us->size
to -1 so the caller will know it's invalid. This is an MFC candidate.

Use high port range by default, and replace the 'h' option with an 'l' option
that forces the ftp code to use the low (default) port range instead.

Don't remember an EINTR, since the caller may want to restart the call.

Support lower-case versions of the proxy environment variables.
