When retrying connect() on management socket, log a message.
Especially useful when waiting for a persistent daemon to
come up after an unexpected exit or service disconnect.

Distinguish between management socket connected and
ready for interaction with the server. The former can
happen even if the server is connected to another client
and thus non-responsive.
Use manage.connected = 1 in place of true when connected
and = 2 when handshake with server completed and ready for
input.

With persistent connections, we may not have the password
or may have a wrong password. Handle such cases while
connecting to the management interface.

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.

Add support for selecting pkcs11-id from the GUI.
Requires --management-pkcs11-id in the config file.
This option is not added by the GUI.
A list of all available pkcs11 certificates are presented to the
user with buttons OK, Cancel, Retry. OK submits the selected
entry, Cancel closes the connection, Retry reconstructs the
list of certificates by querying the daemon again. The latter
can be used to retry after inserting a token.
If no certificates are found, a message suggesting to insert
a token and press 'Retry' is displayed.
The list shows the "Issued-to", "Issued-by" names
(usually the subject & issuer common names) and valid-until
date in current locale for each certificate.

In some cases the service may take a while to startup openvpn.exe,
causing connection to the management interface to timeout. This could
leave behind the OpenVPN process if/when it eventually starts up.
(Trac 905, 1050).
As errors in starting up the OpenVPN daemon are independently
handled, its better to keep retrying the management interface connection
until aborted due to errors or by the user.
- On timeout, log a message on the status window and retry the
management interface connection
- Eliminate the timed-out state that is no longer used
- Call StopOpenVPN() before abort so that OpenVPN daemon
is not left running in case it starts up later.
- In the unlikely event that OpenManagement() fails, show an error
- User can abort by pressing disconnect
A "retrying.." message is logged on to the status window every
15 seconds.
See Trac: #905, #1050

This adds optional support for using OpenVPN3 client
as an alternative to openvpn2.
Just replacing one client with another will not work:
- OpenVPN3 doesn't use interactive service, it uses
"agent" service with completely different protocol. OpenVPN GUI
needs to talk to agent using HTTP and JSON.
- OpenVPN3 management interface realtime notifications must be
explicitly turned on in order for GUI to work.
To enable using openvpn3:
- use any of *-ovpn3 presets (cmake build system)
- ./configure --enable-ovpn3 (mingw)
To switch betweet openvpn2 and openvpn3, see "OpenVPN Engine"
radiobutton group in Settings -> Advanced dialog.
OnReady() implementation was slighly changed - "log all on"
replaced with "log on all" - according to management interface
documentation this is the right way to do it, and also OpenVPN3
only supports "on all" order.
Management interface - enabled OpenVPN3 client (omiclient.exe) and
agent (ovpnagent.exe) are now part of openvpn3 repo.

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
user authenticates.

By some reasons Release build ignores _INC_MATH and includes math.h,
which conflicts with our own log definition. Rename it to log_.
While on it, also rename other enum names for consistency.

- Flag password and username input if these contain an invalid character
(currently only embedded '\n' is disallowed). Shows a popup when OK
is pressed so that the user can correct the input and resubmit.
- Add an error message to the log when the management i/f returns
ERROR for incorrectly parsed commands. Otherwise such errors go
unnoticed.
Note: IDS_ERR_INVALID_USERNAME/PASSWORD need translations.

Support the following echo commands
- "echo forget-passwords": delete passwords internally saved by the GUI
but do not disable the password save feature. Useful when pushed
from the server so that it gets processed after authentication. Also see
management-notes.txt in openvpn docs.
- "echo save-passwords": enables private-key and auth-user-pass passwords
to be saved. Will be effective at startup only if present in the config
file. If pushed from the server, will get used for subsequent
password prompts. Essentially this has the effect of presenting the password
dialogs to the user with save-password checkbox selected. The user may still
uncheck it during the dialog.
Note: echo commands are processed as and when they are received and in the order
received.

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

- Handle early errors (openvpn exits before management connection is up)
with a helpful error message that points the user to view log.
- Include only readable config files in the connection list
- Warn if no connection profiles found
TODO: handle startup errors from interactive service
Proxy settings are fetched from the users Internet Options
for the active connection. If WPAD or a PAC script is configured
they are preferred and used for automatic proxy detection.
Proxy bypass configuration is completely ignored.
