In the test, verify the copied constants are correct.
Also put the test into package utf16 rather than utf16_test;
the old location was probably due creating the test from
utf8, but the separation is not needed here.

* Splits into three server tests.
  - TestStreamConnServer for tcp, tcp4, tcp6 and unix networks
  - TestSeqpacketConnServer for unixpacket networks
  - TestDatagramPacketConnServer for udp, udp4, udp6 and unixgram networks
* Adds both PacketConn and Conn test clients to datagram packet conn tests.
* Fixes wildcard listen test cases on dual IP stack platform.

The dependency was there only to pull in two constants.

If I click on links which should send you to source code (e.g. type, function, etc),
the link is to //src/... (instead of /src/...).
This causes a DNS resolution failure on the browser.

Quick fix is to remove the leading / from package.html
(since godoc.go src links automatically add a leading / as necessary).

Fixes #3193.

CL 3075041 says ARM is not little-endian, but my test suggests otherwise.
My test program is:

    package main
    import ("fmt"; "syscall"; "os")
    func main() {
       err := syscall.Fallocate(1, 1/*FALLOC_FL_KEEP_SIZE*/, 0, int64(40960));
       fmt.Fprintln(os.Stderr, err)
    }

Without this CL, ./test > testfile will show: file too large; and strace shows:
    fallocate(1, 01, 0, 175921860444160)    = -1 EFBIG (File too large)
With this CL, ./test > testfile will show: <nil>; and strace shows:
    fallocate(1, 01, 0, 40960)              = 0

Quoting rsc:
"[It turns out that] ARM syscall ABI requires 64-bit arguments to use an
(even, odd) register pair, not an (odd, even) pair. Switching to "big-endian"
worked because it ended up using the high 32-bits (always zero in the tests
we had) as the padding word, because the 64-bit argument was the last one,
and because we fill in zeros for the rest of the system call arguments, up to
six. So it happened to work."

I updated mksyscall_linux.pl to accommodate the register pair ABI requirement,
and removed all hand-tweaked syscall routines in favor of the auto-generated
ones. These including: Ftruncate, Truncate, Pread and Pwrite.

Some recent Linux/ARM distributions do not bundle kernel asm headers,
so instead we always get latest asm/unistd.h from git.kernel.org (just like
what we do for FreeBSD).

An X.509 path length constrains the number of certificate that may
follow in the chain. This is a little simplistic for a first pass as it
doesn't check self-signed certificates (which don't count towards the
length), but it's conservatively simplistic.

asn1 didn't have an omitempty tag, so the list of additional primes in

This CL changes the behavior of Dial and Listen API family.

Previous Dial and Listen allow a combo of "tcp6" and IPv4 or IPv6
IPv4-mapped address as its argument, but it also makes slightly
different behaviors between Linux and other platforms. This CL fixes
such differences across over platforms by tweaking IP-level socket
option IPV6_V6ONLY. Consequently new Dial and Listen API family will
reject arguments consists of "tcp6" and IPv4 or IPv6 IPv4-mapped
address.

This CL also adds a bit clarified unicast listener tests.

Fixes #2581.
