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.

The H_NOCLEAR flag is used to clear the whole environment whether vars

This leads to incoherent behaviour. If one passes vars to himport_r

If one passes vars to himport_r without the H_NOCLEAR flag, the whole

It makes more sense to keep the variable that is in the current

env: common: accept flags on reset to default env

The function set_default_env() sets the hashtable flags for import_r().
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.
