Unity 4.5 -> Unity Staging

Unity 4.5 - trunk changes

Add unity function to clear domain specific fields from thread object, as they may hold objects from an unloaded domain.

Verify that an image does not contain native code when loading if USE_COREE is not defined. Raises nice exception when loading rather than crashing due to random reasons later on. Fixes case #565179.

This week's Mono fixes

Implement GC_thread_unregister_foreign for pthread based platforms. Call it from mono_gc_unregister_thread.

to guard, in particular, mono_jit_info_table_find (which is called
from thread interrupt handlers).

This week's Mono fixes

Check for special statics at beginning of loop. Avoid traversing thread static or context static variables as roots. Fixes case #555954.

Weekly Mono Fixes

Disable dynamic loading on iOS and OSX (when DARWIN is defined). We don't need it, and it registers a callback with _dyld_register_func_for_add_image and _dyld_register_func_for_remove_image which crash if mono dylib gets unloaded in webplayer.

Case 547363.

particularly in combination with FMOD, and the comments indicate
that it's targeted at platforms we don't support (SPARC).
Case 564033.

fix bug where mono_class_is_subclass_of returns false if the class has not been fully initialized yet. funny that we never hit this before
