lib: connection: Added support for connecting from an explicit source IP.

lib: connection: Add connection_input_halt() and connection_input_resume(). These are convenience functions that remove and add conn->io respectively.

lib: connection: Record the ioloop the connection was last switched to.

lib: Add connection_streams_changed() Originally by Stephan Bosch

lib: connection: Allow switching to a specific ioloop.

lib: connection: Added means to initialize connection to just be added to the connection list.

lib: Use unix streams with connection when using unix socket This makes it easier to send file descriptors over connection

lib: Add connection.allow_empty_args_input This simplifies input_args() callbacks since they don't always have to check for args[0] == NULL. This is enabled by default, because none of the current users want it and it's somewhat unlikely there even will be those in future.

lib: Added connection_input_timeout_reason()

lib: Added connection.connect_started/finished timestamps.

lib: Added connection.last_input_tv for more accuracy

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

Changed type of internet port values to in_port_t everywhere. Created special SET_IN_PORT setting type for internet port values. Created net_str2port() for parsing internet port values. Removed several atoi() invocations in the process.

lib: Added unix_client_connect_msecs setting to connection API.

lib: connection API: Added delayed_unix_client_connected_callback setting. 092a51d80bad commit changed this functionality first to fix lib-http code, but it broke other code. 1fac17a2bc53 reversed the original behavior. This change allows either behavior optionally.

connection: Added support for creating a stream from input/output stream pair.

Comment update.

connection API: Track the number of connections.

Renamed network.[ch] to net.[ch]. The function prefixes already started with net_ instead of network_. And icecap wants to use network.h for other purpose. :)

connection API: Fixed connected() callback to actually allow detecting failed connects.

Added "connection" API for handling client/server connections more easily.

redis: Fixed connection handling.
