a default handler is registered. Fix this.

command: return 1 on unknown command ...

hush now prints the error value if a command returns a value < 0,
so do not return -1 (EPERM) when we encounter an unknown command.
Instead, return 1 so that hush is quiet.

This switches environment variables to use linux list. This is easier
to read. An additional plus is that the environment variables no longer
need an initcall, so malloc is the only requirement for them.

clock: introduce non interruptible timeout ...

is_timeout call poller_call if the timeout is >= 100us

but on 1-wire bus we need to wait 500us and not more than 930us
for the bus reset. So if the poller_call is caller we can not guarantee it.

So for this introduce is_non_interruptible_timeout than we only wait.

Use it for ndelay too.

Add in-system barebox update infrastructure ...

Currently in-system update means to write an arbitrary file to
an arbitrary device. There is no sanity check if the flashed image
is of the right type or will fit onto the device. Furthermore some
SoCs need a special preparation step for their images before
flashing them.

This adds a barebox in-system update infrastructure. Boards can
register update handlers which know how to make the board bootable.
The available handlers can be listed to be able to select one,
different force levels give the user the chance to know it better.

defaultenv: dependencies fixes ...

When a build with a compressed default environment is done and then
environment compression is disabled, barebox_default_env.h is not
regenerated because its dependency (now barebox_default_env) is still
up to date. This results in a corrupt default environment.

This patch fixes this by adding a cmd_env_h and changing barebox_default_env.h
to FORCE. As a side effect barebox_default_env.h is no longer generated in
include/generated/ but in common/ as we have to add barebox_default_env.h to
$(targets) (extra-y).

startup: Print error message when initcall fails ...

There was a time when we used to panic when initcalls failed. Then
it was changed to totally ignore the return value. Instead, print
an error message now so that the user can get a clue when something
bad happened. So initcalls are now recommended to actually return
negative error codes when something fails.

console: Cleanup console activation ...

When CONFIG_CONSOLE_ACTIVATE_ALL is set, the banner will never be printed.
Also, the console buffer is emptied when the first console is registered,
even when it's not enabled.

This patch cleans it up in a way that:

- the console buffer is emptied once the first console is activated, not
  when it's registered.
- Make sure that the banner is printed first, so that we can output things
  to the buffer before the banner is printed without ending up in having
  the banner in the middle of the other boot messages.
- Use IS_ENABLED rather than ifdefs

memory: return error in barebox_add_memory_bank ...

When a memory bank is already registered, return an error code
instead of throwing a bug. This can happen if a board has registered
a memory bank and the same bank is then probed from the devicetree.
