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.

- 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.

When clicking on tray icon, menu items are deleted and then recreated.
Deletion uses o.num_config:
for (i = 0; i < o.num_configs; i++)
DestroyMenu(hMenuConn[i]);
Commit 8e4183f9 ("Add '--command import' command line option")
added BuildFileList() call which modifies o.num_configs
but doesn't touch menus. When clicking on tray icon after import,
abovementioned code attemps to access invalid item in hMenuConn array
and crashes when this is the first imported profile and hMenuConn is NULL.
In other DestryMenu is called with invalid argument.
Fix by recreating popup menus instead of just rescan file list -
this will first delete menus with correct o.num_config value.

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.
v2: multiple occurrences in same line was missed in v1 (/g missing in
sed expression). Fixed.

ParseUrl extended to parse generic URLs and parse
the path. DownloadProfile() function re-factored
for reuse with generic URL.
Also:
- INTERNET_FLAG_RELOAD added to the request
call to force reloading the data from server instead
of using possibly cached data.
- Input box for URL extended in length to about

Use the image in the connecting state icon with background
color replaced by that of the menu for use as the checkmark.
MSDN docs on SetMenuItemBitmaps is unclear about the use of
color bitmaps for checkmarks, but this appears to display well.
(Tested on Windows 10 only).
The bitmap is recreated everytime the popup menus are made
although its sufficient to recreate it when system colours
change.

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.

Currently we show a check mark on connected profiles with no
indication on profiles that may be in the connecting state.
Change this by adding a mark against connecting/reconnecting
profiles. The yellow connecting state icon is used to generate
this mark although a custom designed check mark may look better.
In case of nested configs, the parent menus are marked with a tick
mark and only the profile is marked with the connecting icon.
No change in behaviour for profiles that are connected or
disconnected.

Currently we pop up the status window on double click only
if one connection is active though there is no strong reason to
limit this behaviour. In fact, when multiple connections are
stuck in the connecting state, its very useful to have a quick
way to examine their progress instead of having to drill down
the menu. Especially so when nested menu is in use.
A random variation of up to 100 pixel is added to the initial
position of the status window to avoid all windows falling on
top of each other.
To prevent an explosion of new windows in the very unlikely event
of numerous active connections, restrict the maximum windows
shown to 10.

Add an new command 'rescan' that may be sent to a running
instance of the GUI to force it rescan the config folders.
Use case: with an instance of the is GUI running, one can
manually copy a config file to the config folder and start
it using "openvpn-gui --command rescan" followed by
"openvpn-gui --command connect foo"
v2: The calls to rebuild config file list and recreate
menus is refactored into a function.

As config group is reallocated when full, do not store the pointer to the
parent group. Instead use the id of the group which is invariant across
reallocs. Similarly in connection array store the id of the group
instead of a pointer.
Also
- Do not call ActivateConfigGroups() -- when connections are active:
in this case we want preserve config data structures during rescan.

fixup
- Shows all configs in a subdirectory grouped into a
submenu entry. This hopefully provided a better UX when
there are more than a few 10's of config files.
- Enabled only if number of configs is > 50 or if the
option config_menu_view is set to 2.
To force the current flat listing, set config_menu_view = 1.

- Check system metric for large and small icon sizes and
try to load the correct size instaed of scaling from one size.
Scaling will still happen if the required size is not available
in the icon resource. As we add more icon sizes they will
get automatically used as needed.
LoadImage scales up from next smallest size available. Revisit this
when LoadIconWithScaleDown (Vista+) becomes available in mingw.

- Add new dialog template for generic password/PIN requests
and use it to handle dynamic challenge
Note 1: if dynamic challenge response verification fails, an auth-failed

password even if the user-auth dialog itself succeeeded.

Option ediitng dialogs are in two tabs: General and Advanced.
Proxy related options are left in the proxy tab. Options
config_dir, config_ext, log_dir, script timeouts and
service-only flag are in the Advanced tab. All other more commonly
used flags and options are in the General tab.
- As options are editable, save values in registry only when they differ
from the default values. This leaves the registry clean and makes changing
options and their defaults during updates easier.
- Entries for config_dir and log_dir must be absolute paths.
Environemental variables such as %PROFILEDIR% may be used
to construct these.
- Empty config_dir, config_ext and log_dir entries are silently
ignored (i.e., the current values are left unchanged).
- Store all numeric and boolean parameters in registry as DWORD instead of
strings.
- On startup, the default parameters are loaded, then the registry is read
and finally command-line parameters parsedi.
- Out of range script timeout values in registry truncated with a
warning instead of fatal error. This allows the user to access the
settings dialog and make corrections.
- Save proxy and language settings under the same
HKCU\Software\OpenVPN-GUI key as other options instead of under Nilings.
- Save the current version of the GUI in regsitry so that updates
can be detected and any needed registry cleanup done.
- If no version info is present in the registry any values in OpenVPN-GUI
key in HKCU are deleted for a clean start as this is the first version
to save registry values in HKCU. Language and proxy data if present
under Nilings is migrated.
Note: new controls in the General tab and newly added Advanced tab dialog
are copied to all language files from the English version. These need to
be translated.
