GOROOT_FINAL is a build parameter that means "eventually
the Go tree will be installed here". Make the file name information
match that eventual location.

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).

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
an RSA private key was serialised as an empty SEQUENCE, even for
version 1 structures. This tripped up external code that didn't handle

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.

The motivation for this CL is to support $GOPATH well.
Since we already have a FileSystem interface, implement a
Plan 9-style name space. Bind each of the $GOPATH src
directories onto the $GOROOT src/pkg directory: now
everything is laid out exactly like a normal $GOROOT and
needs very little special case code.
The filter files are no longer used (by us), so I think they
can just be deleted. Similarly, the Mapping code and the
FileSystem interface were two different ways to accomplish
the same end, so delete the Mapping code.
Within the implementation, since FileSystem is defined to be
slash-separated, use package path consistently, leaving
path/filepath only for manipulating operating system paths.
I kept the -path flag, but I think it can be deleted too.

The recent addition of automatic function invocation generated
some troublesome ambiguities. Restore the previous behavior
and compensate by providing a "call" builtin to make it easy to
do what the automatic invocation did, but in a clear and explicit
manner.
Fixes#3140.

I tried before to make relative imports work by simply
invoking the compiler in the right directory, so that
an import of ./foo could be resolved by ./foo.a.
This required creating a separate tree of package binaries
that included the full path to the source directory, so that
/home/gopher/bar.go would be compiled in
tmpdir/work/local/home/gopher and perhaps find
a ./foo.a in that directory.
This model breaks on Windows because : appears in path
names but cannot be used in subdirectory names, and I
missed one or two places where it needed to be removed.
The model breaks more fundamentally when compiling
a test of a package that lives outside the Go path, because
we effectively use a ./ import in the generated testmain,
but there we want to be able to resolve the ./ import
of the test package to one directory and all the other ./
imports to a different directory. Piggybacking on the compiler's
current working directory is then no longer possible.
Instead, introduce a new compiler option -D prefix that
makes the compiler turn a ./ import into prefix+that,
so that import "./foo" with -D a/b/c turns into import
"a/b/c/foo". Then we can invent a package hierarchy
"_/" with subdirectories named for file system paths:
import "./foo" in the directory /home/gopher becomes
import "_/home/gopher/foo", and since that final path
is just an ordinary import now, all the ordinary processing
works, without special cases.
We will have to change the name of the hierarchy if we
ever decide to introduce a standard package with import
path "_", but that seems unlikely, and the detail is known
only in temporary packages that get thrown away at the
end of a build.
Fixes#3169.
