Josh Gao 27241a7a96 Revert "Revert "Add a way to turn off unique_fd's operator int.""
The original commit broke aosp-master-with-phones, because of
vendor libraries the depended on the int versions of libbase functions.

This patch reverts the revert, and also adds ABI-compatibility shims for
the replaced functions.

This reverts commit 2c58e1924a.

Bug: http://b/131312539
Test: treehugger
Test: forrest run of aosp-master-with-phones
