Barebox commands should not perform any action and return 0 if an
invalid parameter was given. This might cause undetected unintended
behvaior when calling commands with wrong options, either manually or
from a script.

We can now detect changes in the USB device hierarchy properly, so
the 'force' option to the usb command is no longer necessary. We just
scan the busses each time the usb command is called.

This patch adds U-Boot 'usb tree' command functionality to barebox.
Here is an example output:
1 ID 0000:0000
| u-boot EHCI Host Controller
|
+-2 ID 05e3:0606
| USB2.0 Hub
|
+-3 ID 10c4:ea60
| Silicon Labs CP2102 USB to UART Bridge Contr P-00-00669
|
+-4 ID 05e3:0606
| | USB2.0 Hub
| |
| +-5 ID 05e3:0608
| | | USB2.0 Hub
| | |
| | +-6 ID 0d8c:000c
| | C-Media USB Headphone Set
| |
| +-7 ID 0d8c:000c
| C-Media USB Headphone Set
|
+-8 ID 0846:1040
NETGEAR NETGEAR FA120 Adapter
The tree view is enabled with 'usb -t'

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

The old output of "help" was just producing a long list, that usually
scrolled of the screen (even on a X11 terminal). This list is more
compact, and also sorted by groups.
The old output format (plus grouping) is now available with 'help -v'.
Example:
Information commands:
?, devinfo, help, iomem, meminfo, version
Boot commands:
boot, bootm, go, loadb, loads, loadx, loady, saves, uimage
...

A command should not be interested in the internal USB core state, so
move the state handling into the core.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

We normally do not expect USB devices to be hotplugged. Instead of
rescanning each time the usb command is called, scan only once.
This makes the usb command safe for being called multiple times
without making already registered USB devices reinitialized. To
really scan multiple times a '-f' option is introduced.

This is unused in all commands and thus can be removed.

This patch makes the USB command optional and makes usb_rescan a
global function. This way we can use USB in noninteractive
environments.
