TapTap ec6692ac41 protocol: add transport I/O vtable over TCP/TLS primitives 
Introduce ProtocolIoOps (send/recv/has_pending), selected once by
protocol_session_init() and protocol_session_set_ssl(), and dispatch the
send, receive and status-read loops through session->ops instead of
branching on session->ssl at runtime.

Each op performs one transfer attempt and classifies the result
(PROTOCOL_IO_RETRY/CLOSED/ERROR), preserving the WANT_READ/WANT_WRITE
wait_events switching, the SSL_ERROR_SYSCALL/EINTR retry, the
SSL_pending poll gating and the deadline handling. The raw read()/write()
fallback lives in the plaintext ops.

Add unit tests: a socketpair session with a counting ops wrapper proving
the loops dispatch through the vtable, and a worker-thread test that
protocol_current_ssl() resolves the bound session's SSL when io_ssl is NULL.

TapTap 1f8d60e30d protocol: resolve TLS transport from the bound session, not thread-local io_ssl 
file_send.c chose between sendfile() and the TLS-aware buffered path by
calling io_get_ssl(), which reads the thread-local io_ssl. A worker thread
that bound a TLS ProtocolSession via protocol_session_bind() never ran the
handshake in that thread, so io_ssl is NULL there and a TLS + --threads
transfer took the raw sendfile() path on an encrypted socket.

Add protocol_current_ssl(), which prefers the bound session's SSL and falls
back to io_ssl on the fd-shim path, and use it in file_send.c. Un-xfail
test_tls_with_multithreading.
