Keep cursor's position consistent when passphrase is reaching
its maximum by adding characters in the middle of the string
The use case is very rare as not many people will attempt to
modify the masked passphrase from the middle.
Previously, CTRL+D used to cause termination of the client. Now, the
command will cancel the agent’s prompts in agent mod. In regular mode
the behavior is unchanged.
method_call and method_reply of type error are mutually exclusive. ell
will never forward method_reply messages to dbus services, so checking
for dbus_message_has_error is pointless.
Previously, command_option_get used to return NULL in the following
two scenarios: when command-line option with a such name didn’t exists
or its argument was not provided. This worked great for the cmd-line
options with the required arguments. With introduction of the cmd-line
options with no or optional arguments the function was changed to return
a boolean value indicating the existence of a such option and then, if
it had an argument - value_out variable would have been set.
Thereafter, this patch modifies the current usages of command_option_get.
Note, in these particular applications of command_option_get there is no
need to check the returned value from command_option_get, since these
options have the required arguments and we can only check if the value_out
parameter has been set or not.
Instead of returning the mode of execution, command_init now
returns whether we are done and need to exit.
Thereafter, the mode of execution is now obtain though the command
module’s API.
Due to the changed IO behavior, pasting of the secrets
into the agent prompt became impossible. The reimplemented
logic allows to add (paste) an arbitrary number of characters
into a desired position of a secret string up to its max lengths.
The deletion has also been reworked to accommodate the new behavior.
In non-interactive mode the agent managers' agent registration callback
precede the actual action command's callback such as 'connect'. iwctl
continues execution until anything else besides the agent registration
callback arrives unless the agent registration has failed.
Previously, agent was registered only for the interactive mode.
This patch enables agent registration in non-interactive mode
taking into consideration the existence of the command-line options.
Enable parsing of the command-line options by the command module.
The parsed command-line option values are stored in command_options
list and made available through the module’s public API:
command_option_get – allows querying options by name,
command_has_options – checks existence of the options.
Previously, on service disappeared event the list of the known
proxy objects was cleared, but pointers to the default entity
per command family wasn’t reset. Reset default entities for
the command families to remove the dead pointers to the deleted
proxy objects.

Switch the command pattern to match the common command scheme
where the entity name (network name) follows the command family name:
From
known-network forget <network name>
To
known-network <network name> forget
In addition, it extracts the network match by name logic into its
own function for the further reusability. In the case of ambiguity
between the network objects with the same SSID but different security
types the logic asks to specify the security type in addition
to the network name as follows:
known-network <network name.security> forget
