[settings] Explicitly separate the concept of a completed fetched setting
The fetch_setting() family of functions may currently modify the
definition of the specified setting (e.g. to add missing type
information). Clean up this interface by requiring callers to provide
an explicit buffer to contain the completed definition of the fetched
setting, if required.

Most network upper-layer drivers do not implement all three methods
(probe, notify, and remove). Save code by making all methods
optional.

[settings] Clarify usage of the term "named setting"
There are currently two conflicting usages of the term "named setting"
within iPXE: one refers to predefined settings (such as show up in the
"config" UI), the other refers to settings identified by a name (such
as "net0.dhcp/ip").
Split these usages into the term "predefined setting" and "named
setting" to avoid ambiguity.

Create an explicit concept of "settings scope" and eliminate the magic
values used for numerical setting tags.

[vmware] Allow settings to be specified in the VMware .vmx file
Allow iPXE settings to be specified in the .vmx file via the VMware
GuestInfo mechanism. For example:
guestinfo.ipxe.filename = "http://boot.ipxe.org/demo/boot.php"
guestinfo.ipxe.dns = "192.168.0.1"
guestinfo.ipxe.net0.ip = "192.168.0.15"
guestinfo.ipxe.net0.netmask = "255.255.255.0"
guestinfo.ipxe.net0.gateway = "192.168.0.1"
