The go/build package already recognizes
system-specific file names like
mycode_darwin.go
mycode_darwin_386.go
mycode_386.s
However, it is also common to write files that
apply to multiple architectures, so a recent CL added
to go/build the ability to process comments
listing a set of conditions for building. For example:
// +build darwin freebsd openbsd/386
says that this file should be compiled only on
OS X, FreeBSD, or 32-bit x86 OpenBSD systems.
These conventions are not yet documented
(hence this long CL description).
This CL adds build comments to the multi-system
files in the core library, a step toward making it
possible to use go/build to build them.
With this change go/build can handle crypto/rand,
exec, net, path/filepath, os/user, and time.
os and syscall need additional adjustments.

Weekday is redundant information for a Time structure.
When parsing a time with a weekday specified, it can create an
incorrect Time value.
When parsing a time without a weekday specified, people
expect the weekday to be set.
Fix all three problems by computing the weekday on demand.
This is hard to gofix, since we must change the type of the node.
Since uses are rare and existing code will be caught by the compiler,
there is no gofix module here.
Fixes#2245.

This is a core API change.
1) gofix misc src
2) Manual adjustments to the following files under src/pkg:
gob/decode.go
rpc/client.go
os/error.go
io/io.go
bufio/bufio.go
http/request.go
websocket/client.go
as well as:
src/cmd/gofix/testdata/*.go.in (reverted)
test/fixedbugs/bug243.go
3) Implemented gofix patch (oserrorstring.go) and test case (oserrorstring_test.go)
Compiles and runs all tests.

I'm in two minds as to whether this should be a function of gotest.
Tests that can flake out like this should be rare enough that we
needn't add more mechanism.

Also simplify sleeper algorithm and poll
occasionally so redundant sleeper goroutines
will quit sooner.

The After code is trivially generalisable to provide support
for this, and it is possible to use AfterFunc to do
things that After cannot, such as waiting
for many events at varied times without an overhead
of one goroutine per event.

Not absolutely certain it's right to do this, but since there's
no error value coming back, it seems reasonable.
Fixes#1392.

The recent linker changes broke NaCl support
a month ago, and there are no known users of it.
The NaCl code can always be recovered from the
repository history.

I have written a tool to verify Printf calls, and although it's not
ready to be reviewed yet it's already uncovered a spate of problems
in the repository. I'm sending this CL to break the changes into
pieces; as the tool improves it will find more, I'm sure.

1) hack regalloc to leave R9 (m) and R10 (g) alone.
the real fix is tricker, but this gets us running
2) fix up the few places in the package sources that
the shortage of registers affects, by simplifying
some expressions.
all of this should be reverted when the right fix is in.
Fixes#1084.
