adbc10fb5e Bug fixes: 
* raise default headroom/tailroom to 512 for worst-case compression
  expansion

* for TCP connections use async_connect instead of connect

* for Time and Time::Duration, handle subtraction reasonably with
  infinite values

* handle possible infinite duration in to_posix_duration

* fix overflow in Time::Duration::to_milliseconds

* call Base::update_now() in ClientProto::start

6674709aba Added ClientConnect class which implements an "always-try-to-reconnect" 
approach, with remote list rotation.  Only gives up on auth failure.

e7a5d9f55b Start process of moving client logic out of cli.cpp into 
general-purpose classes.

Rename ProtoStats to SessionStats and make it more flexible
by using an abstract base class model.

Add a client event queue for the beginnings of a client-backend
API.

Added logic to ProtoContext to invalidate session on certain
kinds of errors in TCP that would be normally be okay in UDP
such as HMAC_ERROR, DECRYPT_ERROR, etc.

Add some alignment adjustment logic for READ_LINK_TCP (3 bytes)
and READ_LINK_UDP (1 byte).

file.  Currently limited to UDP, runs only on Linux, and supports

fb163b65f4 ProtoContext object can now be reused via reset() method. 
Fixed rare bug where client receives auth, goes ACTIVE, but the ACK
response back to the server is dropped causing the server to receive
post-ACTIVE app messages from the client while it's still stuck
in the S_WAIT_AUTH_ACK state.
