Improve the appearance of the "config" user interface by ensuring that
settings appear in some kind of logical order.

[settings] Formalise notion of setting applicability
Expose a function setting_applies() to allow a caller to determine
whether or not a particular setting is applicable to a particular
settings block.
Restrict DHCP-backed settings blocks to accepting only DHCP-based
settings.
Restrict network device settings blocks to accepting only DHCP-based
settings and network device-specific settings such as "mac".

[settings] Apply settings block name in register_settings()
Pass the settings block name as a parameter to register_settings(),
rather than defining it with settings_init() (and then possibly
changing it by directly manipulating settings->name).

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resources has been revoked by the registrant of the domain.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.

[efi] Use EFI-native mechanism for accessing SMBIOS table
EFI provides a copy of the SMBIOS table accessible via the EFI system
table, which we should use instead of manually scanning through the
F000:0000 segment.
[settings] Add the notion of a "tag magic" to numbered settings
Settings can be constructed using a dotted-decimal notation, to allow
for access to unnamed settings. The default interpretation is as a
DHCP option number (with encapsulated options represented as
"<encapsulating option>.<encapsulated option>".
In several contexts (e.g. SMBIOS, Phantom CLP), it is useful to
interpret the dotted-decimal notation as referring to non-DHCP
options. In this case, it becomes necessary for these contexts to
ignore standard DHCP options, otherwise we end up trying to, for
example, retrieve the boot filename from SMBIOS.
Allow settings blocks to specify a "tag magic". When dotted-decimal
notation is used to construct a setting, the tag magic value of the
originating settings block will be ORed in to the tag number.
Store/fetch methods can then check for the magic number before
interpreting arbitrarily-numbered settings.
