Freebsd support

[antenore]

This PR adds support to FreeBSD

@giox069 @weberhofer

When you have time, can you please test this? (works only with FreeRDP 88fa29c as daylight is not implemented in time.h in FreeBSD)

To be compiled with -DHAVE_LIBAPPINDICATOR=off on FreeBSD

@akallabeth is aware. I'm also thinking how to solve it. Should be fixed by FreeRDP/FreeRDP#3179

Updated PR description

@giox069 I'm not sure if the reconnect patch will work (on linux) after this PR, that's why I'm asking to test (try an ssh connection)

[giox069]

@antenore: currently the autoreconnect feature only works with non-ssh tunnelled connections.
The lines which sets sockets timeout are only intended to better detect a ssh tunnel timeout/drop, and are not currently related to the autoreconnect feature, and I don't think your modification will break something.
I will test this PR later.

Thanks.
I'm aware of it, I was asking because on FreeBSD I've a problem with SSH (after my modifications), even with a normal ssh connection and I was wondering if it was related, somehow to these changes, but effectively is not, I've just tested on Fedora.

@antenore: I have tested this PR on Ubuntu, both with and without ssh, and I did a autoreconnect test. All of this is working. Now I'm testing on FreeBSD 10.2, be patient :)
