Log Message:
-----------
TCP: Fix race condition in "proto_tcp.tcp_parallel_handling"
During F_TCPCONN handling by a TCP worker, the @con pointer must *not*
be de-referenced if the READ was successful and connection already
returned to TCP Main. This patch adds a new retcode to the tcp.read API
function in order to achieve this.

this issue!

Log Message:
-----------
TCP debugging: Fine-tune TCP conn history settings
* reduce logline buffer from 100 -> 80
* only keep the last 300 events per connection (down from 2000)
* avoid auto-logging (flushing) of all TCP conn histories to syslog
These changes should reduce the default TCP conn debugging footprint
from ~2GB to ~0.3GB of shared memory, as well as clean up the logs.
