cmd: nvedit: env import can now import only variables passed as parameters

While the `env export` can take as parameters variables to be exported,
`env import` does not have such a mechanism of variable selection.

Let's add the ability to add parameters at the end of the command for
variables to be imported.

Every env variable from the env to be imported passed by parameter to
this command will override the value of the variable in the current env.

If a variable exists in the current env but not in the imported env, if
this variable is passed as a parameter to env import, the variable will
be unset ONLY if the -d option is passed to env import, otherwise the
current value of the variable is kept.

If a variable exists in the imported env, the variable in the current
env will be set to the value of the one from the imported env.

All the remaining variables are left untouched.

As the size parameter of env import is positional but optional, let's
add the possibility to use the sentinel '-' for when we don't want to
give the size parameter (when the env is '\0' terminated) but we pass a
list of variables at the end of the command.

env import addr
env import addr -
env import addr size
env import addr - foo1 foo2
env import addr size foo1 foo2

are all valid.

env import -c addr
env import -c addr -
env import -c addr - foo1 foo2

are all invalid because they don't pass the size parameter required for
checking, while the following are valid.

env import addr size
env import addr size foo1 foo2

Nothing's changed for the other parameters or the overall behaviour.

One of its use case could be to load a secure environment from the
signed U-Boot binary and load only a handful of variables from an
other, unsecure, environment without completely losing control of

hashtable: do not recreate whole hash table if vars are passed to himport_r

When vars are passed to the himport_r function with H_NOCLEAR flag,
those vars will be overridden in the current environment and if one of
those vars is not in the imported environment, it'll be deleted in the
current environment whatever the flag passed to himport_r.

The H_NOCLEAR flag is used to clear the whole environment whether vars
are passed to the function or not.

This leads to incoherent behaviour. If one passes vars to himport_r
with the H_NOCLEAR flag, if a var in vars is not in the imported env,
that var will be removed from the current env.

If one passes vars to himport_r without the H_NOCLEAR flag, the whole
environment will be removed and vars will be imported from the
environment in RAM.

It makes more sense to keep the variable that is in the current
environment but not in the imported environment if the H_NOCLEAR flag is
set and remove only that variable if the H_NOCLEAR flag is not set.

Let's clear the whole environment only if H_NOCLEAR and vars are not
passed to himport_r.

Let's remove variables that are in the current environment but not in

board/BuR/brppt1: implement more flexible boot process

With this commit we do:

- set the bootdelay in all brppt1 defconfigs to 0, this makes
development easier, since we can break into serial console.

- move CONFIG_BOOTCOMMAND from header file to defconfig

- introduce b_mode variable for selecting the final boot-target.
This b_mode represents the boot-switch, which can found on most b&r
targets. On the brppt1 this boot-switch is derived from some gpio and
the bootcounter within the RTC block, making it so possible to force
a boot-target (as example for repair-case).

- refactor the environment for booting new flexible way
primary we want to get some bootscr.img within the mass-storage,
this script then loads everything needed for the boot.
For legacy reason we implement the t30lgcy#x boot targets, booting the
already delivered linux-images.

- make space for the cfgscr within mtdparts on brppt1_nand

Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.

Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
   instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
   especially the H_FORCE flag from do_env_default() in nvedit.c that
   currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
   able to set flags without passing a string and vice versa.

Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.
