menutree: let it select GLOB and GLOB_SORT ...

The menutree doesn't select CONFIG_GLOB, but it depends on it. Without
it will just hang. So let it select it automatically. Also remove the
dependency of CONFIG_GLOB on CONFIG_HUSH, because glob() will run with
the simple shell as well.

Also let CONFIG_MENUTREE select on CONFIG_GLOB_SORT. While is not
strictly needed, many people use menu/00-foo menu/10-bar menu/20-barf
to sort their menu entries. So select it out of convenience.

of: Drop devicetree merge support ...

I assume I am the only person knowing that barebox is able to
merge devicetrees. This feature seems broken for a while now since
trying to merge devicetress results in:

unflatten: too many end nodes

Remove this feature to save the complexity.

complete: Fix completion after options ...

the command specific complete callbacks only work when no
option is typed already. For example "devinfo <tab><tab>"
correctly completes the devices, but "devinfo -x <tab><tab>"
does nothing. That is because the options are passed to
the input string of the completion handlers. Skip the option
string by finding the last space in the input string. This
is not perfect since "devinfo -f<tab><tab>" still does not
work, but it's better than what we have now.

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
   ...

The return value check of the write call is completely bogus. We

instead of all bytes. Properly check for all bytes written instead
and allow write to write less bytes than requested.
Do not use write_full because this file is compiled for userspace
aswell.
