fix DTLS_OVERHEAD and GlobalProtect ESP overhead calculation
GlobalProtect doesn't try to calculate MTU until after it has information on
the ESP ciphersuite, so it can use the real HMAC/encryption key lengths when
calculating ESP overhead. In practice, I have never seen or heard of a GP
VPN that uses anything other than AES128+SHA1, but both the clients and
servers appear to include support for AES256.
DTLS_OVERHEAD was not correctly accounting for possibility of AES256
(32-byte IV).

when connecting to a GlobalProtect portal (not gateway), generate an xmlconfig so that NetworkManager can list all the gateway servers
GlobalProtect distinguishes "portal" and "gateway" servers. Often the same

are for the gateway). The official clients always connect through the
portal. Mostly, the portal configuration is not useful for OpenConnect; it
restricts the behavior of the official clients.
However, the portal configuration does contain a list of allowed gateways

Add support for GlobalProtect ESP tunnel
Most of the existing ESP support code (written for Juniper/nc) can be reused
for GlobalProtect ESP. The ESP algorithms, SPIs, and keys are sent as part of the
getconfig XML response.
GlobalProtect requires a fairly awkward "tap dance" between the TCP mainloop and
the UDP mainloop in order to support ESP:
* Prior to the getconfig XML request, the HTTPS tunnel will not work (even though
the authcookie is already known from the login response) and the ESP tunnel
also will not work (because the ESP keys are not known).
* After the getconfig XML request, either the ESP tunnel or the HTTPS tunnel can
be connected, but not both. As soon as the HTTPS tunnel is disconnected,
the ESP keys are invalidated. On the other hand, if the ESP tunnel stops
responding due to some firewall that interferes with UDP, the HTTPS tunnel
can still be connected.
* Therefore, in order to allow the ESP tunnel to start, the TCP mainloop must
refrain from actually connecting to the HTTPS tunnel unless the ESP tunnel
is disabled or has failed to connect... but it can't wait *too* long
because then the HTTPS keepalive connection may be dropped, and the user
will wonder why no traffic is flowing even though the VPN has allegedly
started. The wait time is currently hard-coded at 5 seconds (half the DPD
interval used by the official clients).
Another quirk of the GlobalProtect ESP support: it uses specially
constructed ICMP request/reply ("ping") packets as the probes for ESP
initiation and DPD.
* These packets must contain a "magic payload" in order to work.
* In most GlobalProtect VPNs, the packets are addressed to the public, external IPv4
address of the VPN gateway server even though they are sent over the ESP
tunnel (???), but in some cases they must be addressed to a different address
which is misleading described as <gw-address> in the getconfig XML response.
Don't blame me. I didn't design this.

Limit netmask on Windows TAP setup to 255.255.255.254
This makes a start on the problems with point-to-point configurations,
discussed in https://github.com/openconnect/openconnect-gui/issues/132
Some work is required in vpnc-script-win.js to make the routing do
anything useful, but at least it's not now *impossible* to persuade
it to pass any traffic.

Attempt to re-open CONIN$ if stdin has been redirected on Windows
This should hopefully fix the problem with --passwd-on-stdin, described
in https://github.com/openconnect/openconnect-gui/issues/101
It doesn't actually work for me in wine, as I get 'Access Denied' when
trying to use ReadConsoleW() on the resulting handle. But wine is strange,
and this at least shouldn't make things any *worse*.
