Add support for bionic fd ownership enforcement.
Add APIs to support the use of bionic's file descriptor ownership
enforcement with java.io.FileDescriptor.
This commit also changes behavior in two ways:
- IoBridge.closeAndSignalBlockedThreads can now throw if close fails.
bionic hides EINTR in its close wrapper, so this should only make
a difference if we fail with EIO (with behavior matching the
reference implementation).
- IoUtils.close will always signal blocked threads.
