change int/pointer conversion using GUINT_TO_POINTER and GPOINTER_TO_UINT macros, otherwise it won't compile on 64bits machines

__BYTE_ORDER is not defined in windows, so we assume we're little endian whenever we're building on windows...

also add the tcp socket to the list of sockets so it gets freed and also gets attached if the context is added after the gahter is made

do not use the same variable name for two different things... with one being inside a smaller scope of the same function... this could lead to confusion...

set gathering to FALSE before signaling the candidate-gathering-done, so we can set_remote_candidates in the signal handler

This reverts commit c8cd93a9.

This reverts commit cbe7189a.

do not send an error response in case the username check failed for gtalk compatibility. we should just drop it like libjingle does.. if the remote candidates weren't added yet, then we'd send the error response which would make the other client match the id, but also fail with integrity check (since the error response has no username in it), and all retransmissions will fail with unmatched_response.

Use the correct size for sockaddr_storage, otherwise it won't work on mac os x. Also use some cleaner code

remove the traffic_after_tick check because it caused problems with jingle. we need a tick every 25 seconds, but with that, the conncheck happens at 0s, and when the keepalive gets called @25s, it gets skipped and we only send our first keepalive after 50seconds... which means that jingle which stops processing if it doesn't receive a ping after 30 seconds, will stop playing our audio from 30 seconds to 50 seconds...

use a different port for the relay to make sure we don't confuse the google relay server between an internal and external connection
