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.

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.

Extend the string comparison of the two paths to include comparing their
file information structure. (See Remarks under the MSDN docs for
GetFileInformationByHandle)
If the strings are identical we treat them as identical without checking
further whether the paths are valid. This matches the current
behaviour. Otherwise, the two paths are treated as identical if both
exist, are accessible and point to the same object in the file system.

- 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
configs
Nested: Force the nested view irrespective of the number
of configs

- Suppress messages with exactly same content as previously
displayed within popup_mute_interval (24h by default). This parameter
may be set on command line as "--popup_mute_interval n" where n is
in hours.
- Command line option '--disable_popup_messages' disables all echo
message popups (window and notification).
This patch only handles suppression of repeated messages during
reconnections.

Some users want to use more deeply nested folders than currently
supported. Increase the max depth to 20 which should be plenty for
all.

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
The number of configs is now unlimited. But there is a limit
of 2^16 menu items which permits only about 2^12 configs to be
displayed in the menu. A warning is shown if the number of
configs exceeds this value.
For a responsive menu keep the number of configs under ~1000.

- Single configs all by itself in a directory are shown as a
member of the parent directory. This allows keeping every
config in its own directory without causing an additional
level of nesting. Eg., import always put each config in
its own directory.
Improves the menu navigation.

- Group all configs in a subdirectory with directory name
as the label.
- If any connection is active, newly found configs are
added to the root group to keep the logic simple.
- Directory hierarchy is scanned up to a depth of 4: i.e.,
config_dir and global_config_dir and its subdirectories
up to 3 levels down.
Only support for scanning configs and attaching group labels
is added here. Rendering the nested menu is the subject of
a later commit.

Treat '--connect foo.ovpn' and '--connect foo' as the same. This matches
with the behaviour of '--command connect foo'.
Note: the argument is first compared against config file names and then
against config names.

- Add config name to caption of password dialogs to help user

- Add new dialog template for generic password/PIN requests

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.

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.

- 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

- 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.
