dhcp_options_handle returns the index into the dhcp_options array.
This is only to be able in the caller to print a debug message when
the index returned from dhcp_options_handle is out of bounds.
Simplify this by printing the debug message in dhcp_options_handle
and not in the caller.

The dhcp code distinguishes between options and params. If sent to the
server they are params, if received from the server they are options.
Unify them all to be options. If it has a handle_param callback it's
a param, if it has a handle callback it's an option.

The eth code registers an OF tree fixup that looks for any nodes in
the Linux oftree that match eth devices loaded in barebox and sets the
mac-address property in those nodes. The purpose is to pass MAC
addresses to the Linux kernel for drivers that expect the MAC address
to be in the device tree.
If barebox does not have a driver for the network device, either
because it has been disabled or because one does not exist, then the
OF tree will not be fixed up to include a MAC address.
The eth code also has a list of MAC addresses which board code has
registered, usually done when it reads the address from an EEPROM or
on-chip memory. If an eth device is created later in the boot, it
will look here for an address.
The registered MAC address list is not used for the OF tree fix up,
and this patch changes that. This way barebox can place a MAC address
in the device-tree without needing a driver for the network device.

In the request packet, we are supposed to copy the IP that the DHCP server

In barebox network packets always go out at the current ethernet
device and are expected to be received from the current interface.
This has some side effects. When for example an NFS is mounted when
one interface is active and the interface is changed afterwards the
NFS packets leave the new interface, but the NFS server won't be
reachable there.
Instead of changing the whole network traffic to the current ethernet
interface we now initialize a network connection with the current
network interface, but then the connection will continue to use that
interface even when the current interface is changed.

This patch does probably too much, but it's hard (and very
cumbersome/time consuming) to break it out. What is does is this:
* each command has one short description, e.g. "list MUX configuration"
* made sure the short descriptions start lowercase
* each command has one usage. That string contains just the
options, e.g. "[-npn]". It's not part of the long help text.
* that is, it doesn't say "[OPTIONS]" anymore, every usable option
is listed by character in this (short) option string (the long
description is in the long help text, as before)
* help texts have been reworked, to make them
- sometimes smaller
- sometimes describe the options better
- more often present themselves in a nicer format
* all long help texts are now created with BUSYBOX_CMD_HELP_
macros, no more 'static const __maybe_unused char cmd_foobar_help[]'
* made sure the long help texts starts uppercase
* because cmdtp->name and cmdtp->opts together provide the new usage,
all "Usage: foobar" texts have been removed from the long help texts
* BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this
is nicer in the source code
* BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself
* made sure no line gets longer than 77 characters
* delibertely renamed cmdtp->usage, so that we can get compile-time
errors (e.g. in out-of-tree modules that use register_command()
* the 'help' command can now always emit the usage, even without
compiled long help texts
* 'help -v' gives a list of commands with their short description, this
is similar like the old "help" command before my patchset
* 'help -a' gives out help of all commands

compact, and also sorted by groups.
The old output format (plus grouping) is now available with 'help -v'.

boot, bootm, go, loadb, loads, loadx, loady, saves, uimage

The command always sets the MAC address of the interface in the code path.
For the static network configuration case it sets it again, due to the
environment variable keyword ("ethaddr") is listed again in the table.
Remove this keyword from the table, because the MAC is already set.
