Selva Nair 5fe0d5225e Make the program DPI aware
- Set dpi-awareness to true in the manifest (i.e., "system-dpi aware")
- Check system dpi and scale and/or position widgets and windows
  that depend on the system dpi (only components within the status
  window are affected).

Note: Declaring dpi awareness eliminates automatic rescaling of
windows that causes blurred text on high dpi monitors.
Windows 8.1 and later allow per monitor dpi setting which is
not handled here.

Selva Nair 1a5ce44a99 Handle dynamic challenge/response
- Add a base64 decode function using Windows CyptoAPI
- Move multibyte to widechar conversions to a function
- Add config name to caption of password dialogs to help user
  identify the request
- 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
message is returned by the server causing the GUI to clear any saved
password even if the user-auth dialog itself succeeeded.

Note 2: Dialog template ID_DLG_CHALLENGE_RESPONSE added to language
files may require translation.

Selva Nair 81ece9690e Check for interactive service only if OpenVPN version is >= 2.4
This makes it less confusing to run GUI v11 with OpenVPN 2.3.x

Selva Nair 5a47986ccb Make options saved in registry editable by user
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.

Selva Nair 1c748e382d Simplify some parameters and registry keys
- Replace allow_password by a runtime check that enables password
  change menu only when the user has write-access to the key file.
- Read exe_path and priority from HKLM and do not duplicate in HKCU.
- Always allow the user to view the config: edit will succeed if user
  has write access.
- Always include the proxy settings tab which is the default.
- Remove the unused power event handling and disconnect_on_suspend key.
- Remove password_attempts -- user can stop the password dilaog
  by clicking cancel.
- Remove allow_service: implicitly enabled if service_only is used.
- Deprecate removed options in cmd-line parser
- Update README.rst
- Close config file before exit in GetKeyFileName
- Close thread and dialog handles in passphrase.c

Selva Nair 5880fdcd02 Save username and optionally passwords
- Username and, optionally, password as well as the private
  key passphrase are saved in config-specific registry keys
- All saved data are kept encrypted using DPAPI
- The passphrase dialog is skipped if a valid saved private
  key password is available. However, the user-auth dialog
  is always presented, prefilled with the saved username
  and password.

Note: A text string "Save password" is added to three dialogs
in all language resource files. Additional text with ids
IDS_MENU_CLEARPASS and IDS_NFO_DELETE_PASS are added to the
STRINGTABLE only in the English language resource file.
All these need translations.

Selva Nair 854d76ae31 Read errors from the service pipe and handle fatal ones
Asynchronously read Input on the service pipe which are mostly
errors reported by the service. Display the errors on the status log
window and to the log file if its not opened by openvpn.
If/when openvpn fails to start or exits with error, close
the connection without waiting for management socket timeout.

v2:
- rebase to master
- fix a bug in setting manage.connected state
- ensure management socket is closed and resources freed before thread exit

Selva Nair 43d0ef3a5a Handle interactive service policy restrictions
When a connection is attempted using a config in a location
that would fail, offer an option to add the user to the "OpenVPN
Administrators" group. This is done using shell-execute which will
show a UAC prompt for elevation. If it fails (due to user chooses
NO or the UAC dialog fails) the connection is not started.

v2 Changes
 - Rebase to master
 - Automaticlaly add the admin group if it doesn't exist
 - Allow unicode strings in debug output
 - Use domain\username to identify user
 - Fix the PrintDebug macro

Minor changes based on user feedback
 - Bring the window back to foreground after UAC prompt completion
 - Show a message if another connection is tried during authorization
 - Do not add user to ovpn_admin_group if it is same as the built-in admin group

Selva Nair 77538dd0d0 Support user and global config directories
- Set default config directory (config_dir) to %UserProfile%\OpenVPN\config
  (saved and read back from HKCU\Software\OpenVPN-GUI\config_dir)

- Add a global_config_dir variable read from HKLM\Software\OpenVPN\config_dir
  or set to OpenVPN-install-path\config

- Scan both directories and their sub directories for connection profiles.
  In case of name conflicts config_dir gets priority over global_config_dir

- Eliminate multiple warnings of duplicate configs

Fixed on review (Thanks to leobasilio@gmail.com)

- Fix wrongly used o.config_dir in 2 locations
- Unrelated: Added missing  CheckIServiceStatus to service.h

Selva Nair 352e44f03d Better error reporting when connection fails to come up
- Handle early errors (openvpn exits before management connection is up)
    with a helpful error message that points the user to view log.

- Warn if no connection profiles found
