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
...

As a new implementation of Y-Modem protocol is available,
switch from old implementation to the new one :
- remove old xyzModem* files
- remove old command loady2
- rename command loady2 to loady

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

With this fix its possible to run loadb -f /dev/ram0
again with the latest next patchstack. Without you will
run into data_abort. Tested with omap3530 beagleboard.

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.

The default download device was /dev/mem
Quote Sascha:
"This is a quite dangerous thing. There are
quite some boards out there which have NOR
Flash on 0x0. With a default file of
/dev/mem we would overwrite U-Boot."
Change default device to image.bin

Default loadb behavior works on packet sized
chunks of kermit data to be put on target file
This would not work good on block devices such
as NAND. solution will be to buffer data up to
standard 4096 chunks before giving to device.

-d represents devices only.. but loadb can
operate on files as well. hence Use -f as
option to select the output file. This is
more representative of what we are trying
to do.

Allow loadb and loady to create file if file not
present. This will allow for downloading a file
to filesystem and cp or doing other operations on
the same. Making this as an option instead of a
default behavior ensures that users intend to
create file when they use -c option
