Refactor the {load,exec} image operations as {probe,exec}. This makes
the probe mechanism cleaner, eliminates some forward declarations,
avoids holding magic state in image->priv, eliminates the possibility
of screwing up between the "load" and "exec" stages, and makes the
documentation simpler since the concept of "loading" (as distinct from
"executing") no longer needs to be explained.

When chainloading rtl8139.pxe from an old Etherboot rtl8139.zrom, iPXE
can end up misreading the first word of the MAC address from the
EEPROM as being all zeroes. This is presumably because Etherboot has
left the serial EEPROM in an unexpected state.
Fix by using the chip select line to reset the SPI device before we
start accessing it.

The default initiator IQN is "iqn.2000-09.org.etherboot:UNKNOWN".
This is problematic for two reasons:
a) the etherboot.org domain (and hence the associated IQN namespace)
is not under the control of the iPXE project, and
b) some targets (correctly) refuse to allow concurrent connections
from different initiators using the same initiator IQN.
Solve both problems by changing the default initiator IQN to be
iqn.2010-04.org.ipxe:<hostname> if a hostname is set, or
iqn.2010-04.org.ipxe:<uuid> if no hostname is set.
Explicit initiator IQNs set via DHCP option 203 are not affected by
this change.
Unfortunately, this change is likely to break some existing
configurations, where ACL rules have been put in place referring to
the old default initiator IQN. Users may need to update ACLs, or
force the use of the old IQN using an iPXE script line such as
set initiator-iqn iqn.2000-09.org.etherboot:UNKNOWN
or a dhcpd.conf option such as
option iscsi-initiator-iqn "iqn.2000-09.org.etherboot:UNKNOWN"

Currently, if both a filename and root-path are present, iPXE will
hook the SAN device but will only attempt to boot from the filename.
Change this behaviour so that both are attempted. Users who want to
avoid booting from the SAN as a fallback can do so via the existing
"skip-san-boot" setting.
This allows for seamless deployment to a SAN target using Windows
Deployment Services (and similar products). A user simply has to
define the root-path option in DHCP and then use WDS to deploy the
system. No further configuration should be required.

We currently use INT 13,00 as an opportunity to reopen the underlying
block device, which works well for callers such as DOS that will use
INT 13,00 in response to any disk errors. However, some callers (such

failures become effectively permanent.

For performing installations direct to a SAN target, it can be very
useful to hook a SAN disk and then proceed to perform a filename boot.
For example, the user may wish to hook the (empty) SAN installation
disk and then boot into the OS installer via TFTP. This provides an
alternative mechanism to using "keep-san" and relying on the BIOS to
fall through to boot from the installation media, which is unreliable
on many BIOSes.
When a root-path is specified in addition to a boot filename, attempt
to hook the root-path as a SAN disk before booting from the specified
filename. Since the root-path may be used for non-SAN purposes
(e.g. an NFS root mount point), ignore the root-path if it contains a
URI scheme that we do not support.

Use the real-mode address ffff:0010 to access the linear address
0x100000, and so test whether or not the A20 gate is enabled without
requiring a switch into flat real mode (or some other addressing
mode).
This speeds up CPU mode transitions, and also avoids breaking the NBP
from IBM's Tivoli Provisioning Manager for Operating System
Deployment. This NBP makes some calls to iPXE in VM86 mode rather
than true real mode and does not correctly emulate our transition into
flat real mode.
Interestingly, Tivoli's VMM *does* allow us to switch into protected
mode (though it patches our GDT so that we execute in ring 1 rather
than ring 0). However, paging is still disabled and we have a 4GB
segment limit. Being in ring 1 does not, therefore, restrict us in
any meaningful way; this has been verified by deliberately writing
garbage over Tivoli's own GDT (at address 0x02201010) during a
nominally VM86-mode PXE API call. It's unclear precisely what
protection this VMM is supposed to be offering.

VLAN device names have the form "netX.Y", e.g. "net0.5" for VLAN 5 on

hierarchical separator in settings block names, with the result that
VLAN device settings cannot be accessed by name.
It would be trivial to treat the VLAN device settings as being a child
of the trunk device settings, but this would cause the VLAN device
settings to be applied to the trunk device: for example, setting
"net0.5/ip" would then apply the IP address to both net0.5 and net0.
Fix by changing the VLAN device name to use "-" instead of ".": the
VLAN device "net0.5" is now "net0-5".
