[build] Expose build timestamp, build name, and product names
Expose the build timestamp (measured in seconds since the Epoch) and
the build name (e.g. "rtl8139.rom" or "ipxe.efi"), and provide the
product name and product short name in a single centralised location.

[main] Defer "initialising devices" message until initialising devices
Allow the "initialising devices" message to show up on consoles which
require initialisation, by deferring it until after initialise() has
completed.

[autoboot] Avoid excess backspacing after displaying Ctrl-B prompt
Remove the newline from the "Press Ctrl-B..." prompt string, so that
prompt() does not attempt to backspace beyond the start of the line.

A scriptlet is a single iPXE command that can be stored in
non-volatile option storage and used to override the default
"autoboot" behaviour without having to reflash the iPXE image.
For example, a scriptlet could contain
autoboot || reboot
to instruct iPXE to reboot the system if booting fails.
Unlike an embedded image, the presence of a scriptlet does not inhibit
the initial "Press Ctrl-B..." prompt. This allows the user to recover
from setting a faulty scriptlet.

Remove the concept of shutdown exit flags, and replace it with a
counter used to keep track of exposed interfaces that require devices
to remain active.

[main] Match "starting execution" and "initialising devices" message style
Add a trailing "ok" to the "initialising devices message", to match
the visual style of the "ok" now added to the "starting execution"
message.

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resources has been revoked by the registrant of the domain.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 IGMP code came from legacy Etherboot and was never updated to work
as a gPXE protocol. There has been no demand for this protocol, so this
patch removes it.

The NFS protocol code came from legacy Etherboot and was never updated
to work as a gPXE protocol. There has been no demand for this protocol,
so this patch removes it.
I have an unfinished NFSv3 over TCP implementation for gPXE that can be
used as the base for new work, should we want to resurrect this
protocol.

[tables] Redefine methods for accessing linker tables
Intel's C compiler (icc) chokes on the zero-length arrays that we
currently use as part of the mechanism for accessing linker table
entries. Abstract away the zero-length arrays, to make a port to icc
easier.
Introduce macros such as for_each_table_entry() to simplify the common
case of iterating over all entries in a linker table.
Represent table names as #defined string constants rather than
unquoted literals; this avoids visual confusion between table names
and C variable or type names, and also allows us to force a
compilation error in the event of incorrect table names.
Having a default script containing
#!gpxe
autoboot
can cause problems when entering commands to load and start a kernel
manually; the default script image will still be present when the
kernel is started and so will be treated as an initrd. It is possible
to work around this by typing "imgfree" before any other commands, but
this is counter-intuitive.
Fix by allowing the embedded image list to be empty (in which case we
just call autoboot()), and making this the default.
Reported by alkisg@gmail.com.
This patch extends the embedded image feature to allow multiple
embedded images instead of just one.
gPXE now always boots the first embedded image on startup instead of
doing the hardcoded DHCP boot (aka autoboot).
Based heavily upon a patch by Stefan Hajnoczi <stefanha@gmail.com>.
Some devices take a very long time to initialise. This can make it
difficult to visually distinguish between the error cases of failing
to start executing C code and failing to initialise a device.
Add a "gPXE initialising devices..." message. The trailing ellipsis
indicates to the user that this may take some time, and the presence
of the message indicates to the developer that relocation etc. all
succeeded.
[romprefix] Add vendor branding facilities and guidelines
Some hardware vendors have been known to remove all gPXE-related
branding from ROMs that they build. While this is not prohibited by
the GPL, it is a little impolite.
Add a facility for adding branding messages via two #defines
(PRODUCT_NAME and PRODUCT_SHORT_NAME) in config/general.h. This
should accommodate all known OEM-mandated branding requirements.
Vendors with branding requirements that cannot be satisfied by using
PRODUCT_NAME and/or PRODUCT_SHORT_NAME should contact us so that we
can extended this facility as necessary.
[iSCSI] Support Windows Server 2008 direct iSCSI installation
Add yet another ugly hack to iscsiboot.c, this time to allow the user to
inhibit the shutdown/removal of the iSCSI INT13 device (and the network
devices, since they are required for the iSCSI device to function).
On the plus side, the fact that shutdown() now takes flags to
differentiate between shutdown-for-exit and shutdown-for-boot means that
another ugly hack (to allow returning via the PXE stack on BIOSes that
have broken INT 18 calls) will be easier.
I feel dirty.
Kill off the static single net device and move to proper dynamic
registration (which we need with the new device model).
Break the (flawed) assumption that all network-layer protocols can use
ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP
protocol using ARP_NET_PROTOCOL() and provide a single method for checking
the existence of a local network-layer address.
