When asking for the preshared-key for WireGuard peers, the secret request
will be very verbose with redundant information. Allow suppressing the entry
id from the prompt.

"nm-macros-interal.h" already includes <errno.h> and <string.h>.
No need to include it everywhere else too.

Most of the times we actually need a NMSecretAgentSimple typed pointer.
This way, need need to cast less.

But even if we would need to cast more, it's better to have pointers
point to the actual type, not merely to avoid shortcomings of C.

Globals are bad. Don't let nmc_readline_helper() access
nm_cli.

Instead, pass nmc_config along. nmc_config albeit being
a complex struct, is much more begning:

  - the configuration nmc_config is initialized early on
    and afterwards immutable.
  - it only contains simple fields, which affect the behavior.
  - it's not a global. While passing around the complex configuration
    struct, it is clear that all callpaths don't access additional
    global information.

Normalize coding style by removing consecutive empty lines from C
sources and headers.

On "nmcli agent all", when the polkit agent fails (while the NM agent
succeeds), the failure is not communicated until the client exits.

Options dependant on specific commands (e.g., nmcli connection show
--active) are now allowed to be processed by the next_arg() function.
This would allow autocompletion to expand options belonging to specific
command first, and then global ones.

Note that global options ("--ask" and "--show-secrets") will be auto-completed
everywhere but only if at least a '-' is passed. Command specific ones
(--temporary, --active, --order) will be auto-completed only after the command
they belongs to but without requiring the user to pass a heading '-'.

Example:
'nmcli connection show -a'
will expand '-a' into '--active', but
'nmcli connection add -a`
will expand '-a' into '--ask' (as it is a global option)

This commit fixes also autocompletion for:
nmcli connection modify --temporary
