BAREBOX_CMD_HELP_START(cp)

commands: harmonize in-barebox documentation
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

commands: group 'help' output
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
...
