sys_util: fix handling EINTR of C system functions
System functions have 2 ways of signalling errors, either via returning -1 as result, and setting errno, or directly returning error code, and we can not distinguish automatically between the 2 options when using InterruptibleResult trait for i32 values. Let's remove this trait for i32 and create 2 explicit macros: handle_eintr_rc and handle_eintr_errno. TEST=cargo test --features plugin; cargo test -p sys_util BUG=None Change-Id: I1dc8e3c023e7bf7875ac3536703eb71fa3206b7b Signed-off-by: Dmitry Torokhov <dtor@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/940612 Reviewed-by: Zach Reizner <zachr@chromium.org>
