	* mini-exceptions.c: Introduce mono_walk_stack_full, which
	allows to select if it's new or old context that is passed to
	the callback.

	* mini-exceptions.c (mono_handle_exception_internal): Handle the
	case when executing a guarded handler from the EH machinery.

	* mini-exceptions.c (mono_install_handler_block_guard): New function
	responsible for checking for handler blocks, installing the guard and
	clearing abort state.

	* mini-posix.c (sigusr1_signal_handler): Call mono_install_handler_block_guard
	to check for handler blocks and skip interruption logic if one was found.

	* mini-trampolines.c (mono_handler_block_guard_trampoline): Function called
	by the handler block guard trampoline. Resumes interruption by raising the
	pending ThreadAbortException.

	* mini.c (create_jit_info): Calculate the end address of a finally block.

	* mini-x86.c (mono_arch_install_handler_block_guard): Patch the return address
	of a finally block to a specified address and return the old one.

	* tramp-x86.c (mono_arch_create_handler_block_trampoline): The handler block
	trampoline patches the original return address and calls the trampoline function.
