Add bssl::SealRecord and bssl::OpenRecord.
This is a C++ interface for encrypting and decrypting TLS application
data records in-place, wrapping the existing C API in tls_record.cc.
Also add bssl::Span, a non-owning reference to a contiguous array of
elements which can be used as a common interface over contiguous
container types (like std::vector), pointer-length-pairs, arrays, etc.
