If '--management' option cannot be parsed in the config file of a

connecting it from the GUI menu fails.
In such cases show an error message instead of silently failing.

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.

- 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.

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.

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.

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
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.
Github issue #468

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.

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.

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.

We didn't use interactive service when gui was running
under admin because of some privilege escalation vulnerability in Vista.
Apparently this issue doesn't exist on Win7 and newer versions so
it is safe to use iservice on those systems.
Introduce "Always use interactive service" option,
which is "on" by default. This should enable users,
who by various reasons run gui as admin, use Wintun.

After a failure the auth-pass dialog is shown with the password
field prefilled but highlighted. This allows the user to easily
overwrite the password or resubmit the old password if the
failure was temporary.
After a private key passphrase failure, the dialog is not
prefilled with saved password as this failure happens locally
and in such cases the password is very likely wrong.
If the user aborts the dialog by pressing cancel, the saved
password will get used during the next connection attempt.

- 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.
