[Freeciv-Dev] patch: connection.c (PR#447)

[David Pfitzner <dwp@xxxxxxxxxxxxxx>]

This patch adds a new module common/connection.[ch], containing 
connection-specific stuff moved out of packets.[ch].  

This is not essential, but I think its a good idea: it separates 
stuff about handling individual packets and their many specific
types (left in packets.c) from the stuff about connections in 
general, including some low-level socket stuff.

The patch also has a few related re-organisation changes, the 
largest being moving cmdlevel stuff from player module to new
connection module, since none of the player stuff uses it, and 
the access is really tied to connections, not players (certainly 
currently).  I also expanded a few comments for some of the 
connection functions which were moved, and made
flush_connection_send_buffer() static.
