Macro wpilib_sys::maybe_hal_call

macro_rules! maybe_hal_call {
    ($function:ident($($arg:expr),*)) => { ... };
    ($namespace:path, $function:ident($($arg:expr),*)) => { ... };
}

Like hal_call!, but ignores the status code and returns the functions result anyway. This sounds bad, but WPILibC does it in some places, and there isn't really a reason to needlessly complicate the public interface.
