[ios/atv2/jenkins] - lower default iOS SDK from 4.3 to 4.2 - there is a flaw in 4.3 (mismatch between runtime and headers) which leads to crashing on iOS < 4.3 when using mysql or smb. Gotham will be the last version with 4.2 SDK - and so iOS 4.2 support.
fixed runtime crash, disable gnutls, missing symbol on 10.6 boxes
[WIN32] fixed: added missing directsound return codes.
