BoringSSL (or OpenSSL) require that when SSL_write fails due to the
underlying socket being blocked, it's retried with the same parameters
until it succeeds. But we weren't doing this, and our socket
abstraction doesn't have an equivalent requirement. So when this was
occurring, we would just end up trying to send the next RTP or STUN
packet (instead of the packet that couldn't be sent), and BoringSSL
doesn't like that.
So, when this condition occurs now, we'll simply enter a "pending write"
mode and buffer the data that couldn't be completely sent. When the
underlying socket becomes writable again, or if Send is called again
before that happens, we retry sending the buffered data. Making both
BoringSSL and the upper layer of code that expects normal TCP socket
behavior happy.
Also adding some more logging, and fixing an issue with VirtualSocketServer
that made it behave slightly differently than PhysicalSocketServer when a
TCP packet is only partially read.

The only thing the physical socket server was used for was
"Wait"/"WakeUp", but it could be replaced by a simple rtc::Event.
So, removing this dependency makes things less confusing; the fact that
VirtualSocketServer takes a PhysicalSocketServer may lead someone to
think it uses real sockets internally, when it doesn't.

Instead, make the pointer to the associated socket server a
construction time const, and delete its lock.
Introduces a helper class AutoSocketServerThread for code
(mainly tests) which need a socket server associated with
the current thread.

These defines don't work any more, so they only cause confusion:

Reason for revert:
Broke chromium build, due to a config being removed. Will add it back and remove the dependency in a chromium CL.

This helps a lot on Android devices where the user threads can be scheduled with low priority when the app is in the background, causing spurious significantly delayed before a packet can be read from the socket. With this patch the timestamp is taken by the kernel when the packet actually arrives.

This propagated into various other places. Also had to #include headers that
were implicitly pulled by "scoped_ptr.h".

1) Added SetMode() to SSLAdapter and OpenSSLAdapter so the mode can be set to
SSL_MODE_DTLS
2) OpenSSLAdapter overrides SendTo() and RecvFrom() to handle calls from
TurnPort via AsyncUdpSocket
3) OpenSSLAdapter derives from MessageHandler to implement an internal DTLS
timer
4) Updated SSLAdapter unit tests
