Selva Nair d6775b9b71 Persistent connections: show an error msg when connect fails
If '--management' option cannot be parsed in the config file of a
persistent profile (due to missing option, unreadable password etc.),
connecting it from the GUI menu fails.
In such cases show an error message instead of silently failing.
The message is shown only during manual connect attempts,
not during auto-connect or resume.

Selva Nair 7f794eec3d Add a button for detaching from the management interface
Useful for releasing the management interface if the user wants to
connect to it by other means.

Detached connections are set to state = detached (no disconnected)
and auto_connect disabled, so that they could be handled properly
during a re-attach.

Selva Nair 0e76e4b544 Option to disable attaching to persistent connections
Three options are provided to control scanning of persistent
(pre-satrted) connections in config-auto folder, and how they
are attached to.

Auto: Scan and list persistent connections and attach to their
      management i/f automatically at startup, and periodically
      retry on failure to attach.
Manual: Scan and list as above, but do not attach automatically.
      User can attach to such connections by manually clicking
      connect.
Never: Do not scan config-auto folder.

Default is "Auto"

Change of this setting in the settings menu will take full effect
only if none of the connections are in connecting/connected/detached
state so that the connection list can be updated. Otherwise
restart the GUI.

Selva Nair 8f0dbbc8a3 Always check status of automatic service
- Remove service-only mode (start/stop service) which has not been in
  use since we moved to running the GUI as limited user.
  Also its not very useful as it does not allow any control of
  service-started daemons

- Keep CheckServiceStatus and always check the status of
automatic service.

The status of the service will be used to toggle supporting
control of persistent connections started by the service.

Selva Nair 428ee29246 Add support for marking connections as persistent
Persistent connections have openvpn.exe daemon started
external to the GUI (e.g., by the automatic service).
This patch adds support for attaching to the management
i/f of such daemons from the GUI and control the connection.

The GUI never stops or starts the openvpn.exe process in this
case. Instead, connect and disconnect buttons signal the
management interface of a running openvpn.exe process to start
the tunnel by attaching to mgmt i/f and sending hold-release if
needed  or stop it and wait in management-hold state
(see DisconnectDaemon()).

When the GUI process exits, persistent connections are left in their
current state using DetachOpenVPN().

No connections are marked as persistent as yet. That is done
in a following commit.

Selva Nair 84be448777 Handle pkcs11-id query from daemon
Add support for selecting pkcs11-id  from the GUI.
Requires --management-pkcs11-id in the config file.
This option is not added by the GUI.

A list of all available pkcs11 certificates are presented to the
user with buttons OK, Cancel, Retry. OK submits the selected
entry, Cancel closes the connection, Retry reconstructs the
list of certificates by querying the daemon again. The latter
can be used to retry after inserting a token.

If no certificates are found, a message suggesting to insert
a token and press 'Retry' is displayed.

The list shows the "Issued-to", "Issued-by" names
(usually the subject & issuer common names) and valid-until
date in current locale for each certificate.

Lev Stipakov d60325acde Support for OpenVPN 3
This adds optional support for using OpenVPN3 client
as an alternative to openvpn2.

Just replacing one client with another will not work:

 - OpenVPN3 doesn't use interactive service, it uses
"agent" service with completely different protocol. OpenVPN GUI
needs to talk to agent using HTTP and JSON.

 - OpenVPN3 management interface realtime notifications must be
explicitly turned on in order for GUI to work.

To enable using openvpn3:

 - use any of *-ovpn3 presets (cmake build system)

 - ./configure --enable-ovpn3 (mingw)

To switch betweet openvpn2 and openvpn3, see "OpenVPN Engine"
radiobutton group in Settings -> Advanced dialog.

OnReady() implementation was slighly changed - "log all on"
replaced with "log on all" - according to management interface
documentation this is the right way to do it, and also OpenVPN3
only supports "on all" order.

Management interface - enabled OpenVPN3 client (omiclient.exe) and
agent (ovpnagent.exe) are now part of openvpn3 repo.

Provide more space for challenge dialog text (#469)
* Provide more space for challenge dialog text

We do use a re-sizeable dialog box for dynamic challenge-response
to cater for potentially long lines of challenge text. But the
space specified for the widget is enough for only a single short line
(~60 characters) of text.

Increase the horizontal and vertical space to allow for up to
two lines of ~120 characters per line.

The default size of the Window is not changed. But it is
automatically resized if the space required for the text
is longer than the window width minus some margin. The max
horizontal size of the window is capped at 640 nominal pixels
as longer text will be wrapped in to two lines.

Selva Nair 9c82e666d8 Show a prompt during profile import using --import
The user is prompted with a message showing the config
name that will be imported. The user can accept or cancel
the operation.

If the user was already prompted for over-write permission
because a config with the same name exists, no further dialog
is shown.

Import using the menu (Import File...) is not affected.

Rationale:
We want to set "Import" as the default verb for the context
menu of .ovpn files. This will allow import of configs by
double-click. Also when .ovpn file is downloaded using a browser,
setting the default bowser action to "open" will result in an import.
In such cases a silent import action could be surprising, and a
prompt showing what is being imported could provide a better UX.

On the flip-side, the prompt/dialog will also be shown when import
is done from the context menu of .ovpn by "right click and
choose import" or when "openvpn-gui.exe --import foo"
or "openvpn-gui.exe --command import foo" is executed. As import
is an action that does not result in an immediately visible result
(unlike, say, edit or print), a prompt requiring user action is of
some value even in these cases. At worst it's a minor annoyance.

Selva Nair 56ee704501 Use C standrad compliant printf specifications
%S --> %hs in wide format strings, %ls otherwise
%s --> %ls in wide format strings, unchanged otherwise
%c --> %lc in wide format strings

Resource files together have about 970 lines affected and
were edited by looping through all with
sed -i 's/%S/%hs/g' $file
sed -i 's/%s/%ls/g' $file
All other files were manually changed (about 85 lines).

Recent versions of mingw-w64 implicitly turns on __USE_MINGW_ANSI_STDIO
if _GNU_SOURCE, _XOPEN_SOURCE etc are defined (which we do usei).

This breaks non-standard spec such as %S. Anyway, we have been
gradually getting rid of those.

MSVC builds should not be affected.

Selva Nair c47c3bf81a Remove MAX_CONFIGS limit using WM_MENUCOMMAND for menu messages
We currently use WM_COMMAND message which is delivered with the
ID of the menu item requiring a unique ID for every command
(connect, disconnect etc..) for each connection profile. Instead,
use WM_MENUCOMMAND so that the message delivers a handle to the
menu and the position index of the menu item.

Connection menu array is now dynamically allocated. Yet, there
is still a limitation on the number of configs as the config
index + mgmt_port_offset must be < 65536 to be usable as a port
number. The error message shown for "too many configs" is reworded.
(English language file only).

Note: The current way of selecting the management port based on the
index of the config file increases chances of port conflicts
when the number of configs is large. It could be useful to change
this logic but that is beyond the cope of this PR.

Selva Nair f098f2fee4 Make 'management port offset' and 'menu view' user-configurable
- Add an option in the advanced settings menu for
the management port offset. Allows any value in the
range 1 to 61000 which with upto ~4000 added as connection
id keeps it in range.

Default is the currently hard coded value of 25340.

As Windows has no concept of privileged ports and the ephemeral
range used varies from version to version, no attempt is made to
avoid conflicts with ports in use.

- Add an option to choose the config menu view from the
advanced settings with three options:

Auto:   Automatically switch to the nested view when
        number of configs exceed a limit (currently 25)
Flat:   Force the flat view irrespective of the number of

After a private key passphrase failure, the dialog is not

If the user aborts the dialog by pressing cancel, the saved
password will get used during the next connection attempt.

Selva Nair 0f21030774 Support sending commands to running instance
- New option --command <action> <params> to send commands to
  a running instance of openvpn-gui.exe
  Supported actions are
      connect, disconnect, reconnect
  each of which takes the name of the config (with or without the
  extension .ovpn) as a parameter;
      disconnect_all, exit
  which take no parameter and
      silent_connection
  which takes an optional parameter = 0 or 1 (1 is the default)

  Examples: with the gui running, start a new instance as

  openvpn-gui.exe --command disconnect myvpn : ask running instance
                        to disconnect myvpn if connected
  openvpn-gui.exe --command status myvpn     : ask running instance
                        to show the status window for myvpn if available
  openvpn-gui.exe --command disconnect_all   : ask running instance
                        to disconnect all active connections

- The second instance exits after issuing a SendMessage to the
  already running instance. If no action is specified, the running
  instance is notified to show a balloon to alert the user

- These messages may also be sent from scripts as COPYDATA messages
  with the wData element specifying the action to execute and lpData
  a pointer to the parameter. The dwData param must be one of
  WM_OVPN_xxx with xxx = START, STOP, RESTART, STOPALL, EXIT or
  SILENT. See main.h for their values.
