1) Added missing checks for CreateEvent which also required the following related changes: - changed freerdp_context_new API to BOOL - changed freerdp_peer_context_new API to BOOL - changed pRdpClientNew callback to BOOL - changed pContextNew callback to BOOL - changed psPeerAccepted callback to BOOL - changed psPeerContextNew callback to BOOL 2) Fixed lots of missing alloc and error checks in the changed code's neighbourhood. 3) Check freerdp_client_codecs_prepare result to avoid segfaults caused by using non-initialized codecs. 4) Fixed deadlocks in x11 caused by missing xf_unlock_x11() calls in some error handlers 5) Some fixes in thread pool: - DEFAULT_POOL assignment did not match TP_POOL definition - don't free the pool pointer if it points to the static DEFAULT_POOL - added error handling and cleanup in InitializeThreadpool
