Merge #63

63: Remove alloc_error_handler r=adamgreig a=jannic

With rust-lang/rust#102318 default_alloc_error_handler has been stabilized, ie. the default error handler is enabled by default.

Therefore, it's no longer necessary to provide an alloc_error_handler if the desired error handling is equivalent to a panic.
