Backs out 952d14a9e508 (bug 707173), c170c678c9ac (bug 708305), 0a5f66d5d8e4 (bug 707662), 3204b70435fe (bug 706236) and the main landing range 48807fde0339:0bd45ead1676 (bug 528288).
raise sockettransportservice max sockets to 550 from 50 for linux, os
x, and windows >= xp. This does not change the default http
max-connections config (which remains at 30), but does allow
configurations above 50 to work and will enhance the utility of other
systems that use the sockettransportservice.
win9x provides a small number of sockets (100), so we just leave the
limits unchanged there out of conservatism.

don't send the keep-alive request header. It is redundant to
connection: keep-alive and we don't send the right syntax anyhow.

Losing a TCP SYN requires a long painful (typically 3 second) delay
before being retried. This patch creates a second parallel connection
attempt for any nsHttpConnection which has not become writable before
a timeout occurs.
If you assume .5% packet loss, this converts a full 3 second delay
from a 1 in 200 event into a 1 in 40,000 event.
Whichever connection establishes itself first is used. If another one
has been started and it does connect before the one being used is
closed then the extra one is handed to the connection manager for use
by a different transaction - essentially a persistent connection with
0 previous transactions on it. (Another way to think about is
pre-fetching a 3WHS on a high latency connection).
The pref network.http.connection-retry-timeout controls the amount of
time in ms to wait for success on the initial connection before beginning
the second one. Setting it to 0 disables the parallel connection, the
default is 250.
