forked from Mirrors/freeswitch
Rework of Filter's handling of the socket with freeswitch, the previous implementation was a serious cheat. We now properly handle the Content-Length tag and go out of line based mode and into length mode.
Also updated the console to show replies to commands. git-svn-id: http://svn.freeswitch.org/svn/freeswitch/trunk@3168 d0543943-73ff-0310-b7d9-9358b9ac24b2

that don't have \n at the end of their data block
