During the wait for threads to exit, we no longer sleep, but
continue pumping messages. Disable the tray icon during this
period to not allow user interaction with the main menu.

Currently we use an array of connection pointers which needs
to be reallocated when space runs out. But, that happens from
the main thread while the status thread may be referring to those
pointers. Its very hard to fence against possible invalid memory
access. Instead, use a list so that connection pointer never
changes once created.
The connection list is no longer recreated from scratch even when
no connections are active. This means configs added while GUI is
running will always appear at the bottom of the root group listing
until the GUI is restarted.
TODO: This behaviour could be improved by scanning through the groups to
graft new configs at the right branch in the config-group tree.
v2: removed unused references to SetMenuStatusById()

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.

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.

This is the first patch from series which implemets
importing profile from URL, currently implemented
by OpenVPN Access Server.
Move "Import from file" menu item under new "Import"
item. Add "Import from AS..." item under "Import", which
opens new profile import dialog.

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.

- 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.
TODO: Make config_menu_view user configurable.

- 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.

but is more conveniently accessible from the tray menu.

- 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.
