e257cd8aae net: extend sockaddr interface to the all address families 
This CL extends existing sockaddr interface to accommodate not only
internet protocol family endpoint addressess but unix network family
endpoint addresses.

This is in preparation for runtime-integrated network pollster for BSD
variants.

Update #5199

Makes it possible to return the spent runtime.PollDesc to
runtime.pollcache descriptor pool when netFD.connect or
syscall.Listen fails.

4b7bf73c4b net: avoid use of listener socket options on active open sockets 
This CL ensures we use the correct socket options for
passive and active open sockets.

For the passive open sockets created by Listen functions,
additional SO_REUSEADDR, SO_REUSEPORT options are required
for the quick service restart and/or multicasting.

For the active open sockets created by Dial functions, no
additional options are required.

bfb32dc6d1 net: use original raddr if getpeername fails 
This CL updates CL 7511043;
- adds new test cases for both UDPConn and UnixConn,
- makes sure unnamed UnixAddr handling,
- replaces t.Errorf with t.Fatalf in sockname related test cases.

Fixes #3721 (again).
Fixes #3838 (again).

b000f2286c net: more refactoring in preparation for runtime integrated pollster 
Move pollServer from fd_unix.go to fd_poll_unix.go.
Add pollServerInit(*NetFD) to allow custom initialization.
Add pollServer.Close(*NetFD) to allow custom finalization.
Move setDeadline() to fd_poll_unix.go to allow custom handling of deadlines.
Move newPollServer() to fd_poll_unix.go to allow custom initialization.
No logical code changes.
The next step will be to turn off fd_poll_unix.go for some platform
(I have changes for darwin/linux) and redirect it into runtime. See:
https://golang.org/cl/7569043/diff/2001/src/pkg/net/fd_poll_runtime.go

9fb96991e6 net: fix data races on deadline vars 
Fixes #4434.

This proposal replaces the previous CL 6855110. Due to issue 599, 64-bit atomic operations should probably be avoided, so use a sync.Mutex instead.

Benchmark comparisons against 025b9d070a85 on linux/386:

CL 6855110:

benchmark                        old ns/op    new ns/op    delta
BenchmarkTCPOneShot                 710024       727409   +2.45%
BenchmarkTCPOneShotTimeout          758178       768620   +1.38%
BenchmarkTCPPersistent              223464       228058   +2.06%
BenchmarkTCPPersistentTimeout       234494       242600   +3.46%

This proposal:

benchmark                        old ns/op    new ns/op    delta
BenchmarkTCPOneShot                 710024       718492   +1.19%

5b425cc3ab undo CL 6855110 / 869253ef7009 
64bit atomics are broken on 32bit systems. This is issue 599.

linux/arm builders all broke with this change, I am concerned that the other 32bit builders are silently impacted.
