libchromeos: Implement chromeos::Stream-based BIO for OpenSSL

In order to implement a TLS/SSL stream, OpenSSL requires BIO-based
abstraction around our Stream classes. This change adds limited support
for chromeos::Stream interface for OpenSSL's BIO framework.

A new function chromeos::BIO_new_stream() can be used to create a BIO*
that has a reference to underlying chromeos::Stream and then using
BIO_read() and BIO_write() will end up calling Stream::ReadNonBlocking()
and Stream::WriteNonBlocking().

This functionality is going to be used in a follow-up CL that implements
a TLS stream on a socket.
