For Import from URL, require that response
from server must have
content-type: application/x-openvpn-profile
This reduces chances of mistyped input causing
import of random html pages as connection profile.

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
50 characters wide.

Import a config file from command line as
`openvpn-gui.exe --command import <file-path>`
The command is send to a running instance if any.
Otherwise the GUI extecutable is started and
the import processed.
`openvpn-gui --import <file-path>`
is interpreted as the same command.

Currently we construct the destination path and check whether
it exists. This could miss a connection profile with same
name in another directory.
If a config with same name is found we set it as the destination,
and ask the user for permission to overwrite. However, if the duplicate
is in the global_config_dir, the behaviour is not changed -- that is,
the config is imported with no further prompts.
Also fix the use of same buffer as destination and source in
swprintf(). It seems to work, but is not 'legal'.

When 2FA is enabled, server (such as AS)
replies with HTTP 401 and issues a challenge.
Use existing facilities to parse CRV message
and prompt user for a response, then call REST
method again with encoded response as HTTP auth password.

ask if user wants to continue.

Commit 131c75e5 ("Notify dialog windows when OpenVPN state changes") added callback
function, but forgot to specify __stdcall calling convention with CALLBACK keyword.
This is not an issue for x64 builds, but x86 requires __stdcall calling convention for callbacks,
otherwise compiler throws an error:

Currently we show a messagebox with OK/CANCEL when response is

Instead, show the "GenericPass" dialog with input disabled.

Use a custom message to pass state change notification from OpenVPN
to all top level windows in the thread. Currently only the pending auth
dialog responds to this message by closing when the state changes.
The state change could be due to timeout, errors or success via
out-of-band authentication which makes the dialog no longer valid.
The case of CR_TEXT messages that do not require a response is handled
in the next commit.

This adds support for crtext method of pending authentication,
used by Access Server 2.7 and newer.
When enabled on the server side and on the client side (IV_SSO=crtext),
server returns AUTH_PENDING with Info command like:
CR_TEXT:R,E:Enter Authenticator Code
Client prompts user for the response and sends base64-encoded response
to the server via management interface command:
cr-response SGFsbG8gV2VsdCE=
See https://github.com/OpenVPN/openvpn/blob/master/doc/management-notes.txt (crtext part)

This adds support for web-based extra authentication, which may be
used by OpenVPN Cloud. When enabled and client sends IV_SSO=openurl,
server pushes Info command OPEN_URL:<url>. The client opens that URL and

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.

Use an empty password to clear any existing password in the
private key file. If not empty, the requirement of minimum 8
characters is retained.
For PEM key file, an empty password will clear encryption on
the key. For pkcs12 files it will set an empty password.
As use of an empty password is the default first try in
OpenVPN.exe when reading pkcs12 file, this effectively leads
to the user not prompted for a private key password during
connection setup.

In this case, as per management-notes.txt, a CRV1 response with
an empty password should be submitted. Currently we ignore
such "challenges" causing the regular user-auth dialog to be shown
instead.
Fix by displaying the message received from the server. Depending
on user action (OK or CANCEL), a properly formatted reponse with an
empty password is returned or the connection is aborted.

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.
