ftp_data_deliver() does nothing except pass through the received data
to the xfer interface, and so can be eliminated by using a
pass-through interface.

Remove data-xfer as an interface type, and replace data-xfer
interfaces with generic interfaces supporting the data-xfer methods.
Filter interfaces (as used by the TLS layer) are handled using the
generic pass-through interface capability. A side-effect of this is
that deliver_raw() no longer exists as a data-xfer method. (In
practice this doesn't lose any efficiency, since there are no
instances within the current codebase where xfer_deliver_raw() is used
to pass data to an interface supporting the deliver_raw() method.)

Standardise on using ref_init() to initialise an embedded reference
count, to match the coding style used by other embedded objects.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

The default user and password are used for anonymous FTP by default.
This patch adds support for an explicit user name and password in an FTP
URI:
imgfetch ftp://user:password@server.com/path/to/file

The documentation in xfer.h and xfer.c does not say that the metadata
parameter is optional in calls such as xfer_deliver_iob_meta() and the
deliver_iob() method. However, some code in net/ is prepared to
accept a NULL pointer, and xfer_deliver_as_iob() passes a NULL pointer
directly to the deliver_iob() method.
Fix this mess of conflicting assumptions by making everything assume
that the metadata parameter is mandatory, and fixing
xfer_deliver_as_iob() to pass in a dummy metadata structure (as is
already done in xfer_deliver_iob()).
-Wformat-nonliteral is not enabled by -Wall and needs to be explicitly
specified.
Modified the few files that use nonliteral format strings to work with
this new setting in place.
Inspired by a patch from Carl Karsten <carl@personnelware.com> and an
identical patch from Rorschach <r0rschach@lavabit.com>.
When an error reply (not 1xx, 2xx or 3xx) was received, ftp_reply()
invoked ftp_done() to close connections, but did not return, and the
rest of code in this function could try to send commands to the closed
control connection.

Based on a patch contributed by Sergey Vlasov <vsu@altlinux.ru> :
In my testing with "qemu -net user" the 226 response to RETR was
often received earlier than final packets of the data connection;
this caused the received file to become truncated without any error
indication. Fix this by adding an intermediate state FTP_TRANSFER
between FTP_RETR and FTP_QUIT, so that the transfer is considered to
be complete only when both the end of data connection is encountered
and the final reply to the RETR command is received.
will enable us to cascade async operations, which is necessary in order to
properly support DNS. (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).
Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
