Fixes#1998.
ztypes_linux_arm.go has been regenerated on an arm5 debian sid host and
includes a few new constants.

mode (e.g. pkg/big/?m=src).

The following ciphersuites are added:
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
This change helps conform to the TLS1.1 standard because
the first ciphersuite is "mandatory" in RFC4346

Socket descriptors are not closed when fd.connect() fails during generic socket creation.
After a connection failure [ECONNREFUSED] descriptors are left in SYN_SENT state indefinitely (unless they get an explicit RST). Repeated failed connections will eventually cause your program to hit the user/system max-open-files limit.
Fixes#2349.

Plus the need for a second in-memory buffer.
Plays a bit fast and loose with the contents of a byte buffer,
but saves a potentially huge allocation. The gotest
run is about 10% faster overall after this change.

string literals used as package qualifiers are now prefixed with '@'
which obviates the need for the extra ':' before tags.

With this in place, a TLS server is capable of selecting the correct
certificate based on the client's ServerNameIndication extension.
The need to call Config.BuildNameToCertificate is unfortunate, but
adding a sync.Once to the Config structure made it uncopyable and I
felt that was too high a price to pay. Parsing the leaf certificates
in each handshake was too inefficient to consider.

Implement a locking model based on the current linux model - a
tri-state mutex with active spinning, passive spinning and sleeping.

Also: Fewer calls to flush for faster processing (once per identifier
or error instead of once per token).

FileSet deserialization (Read) uses its own instance of a gob decoder.
If the FileSet data may be followed by other data on the reader, Read
may consume too much data that is lost unless the reader implements
ReadByte.
Also: Minor internal refactoring for symmetry.

This is a semantic but no API change. It is a cleaner
implementation of pure filtering. Applications that
need function bodies stripped can easily do this them-
selves.

Removed the URL form parameter "f=text" in favor of a more
flexible mode parameter "m" which now accepts a list of mode
flags as documented in doc.go.

This CL introduces the go.Example type and go.Examples functions that
are used to represent and extract code samples from Go source.
They should be of the form:
// Output of this function.
func ExampleFoo() {
fmt.Println("Output of this function.")
}
It also modifies godoc to read example code from _test.go files,
and include them in the HTML output with JavaScript-driven toggles.
It also implements testing of example functions with gotest.
The stdout/stderr is compared against the output comment on the
function.
This CL includes examples for the sort.Ints function and the
sort.SortInts type. After patching this CL in and re-building go/doc
and godoc, try
godoc -http=localhost:6060
and visit http://localhost:6060/pkg/sort/

The malloc sample trigger was not being set in a
new m, so the first allocation in each new m - the
goroutine structure - was being sampled with
probability 1 instead of probability sizeof(G)/rate,
an oversampling of about 5000x for the default
rate of 1 MB. This bug made pprof graphs show
far more G allocations than there actually were.

Fixes#2337.
Unfortunate sequence of events is:
1. maxcpu=2, mcpu=1, grunning=1
2. starttheworld creates an extra M:
maxcpu=2, mcpu=2, grunning=1
4. the goroutine calls runtime.GOMAXPROCS(1)
maxcpu=1, mcpu=2, grunning=1
5. since it sees mcpu>maxcpu, it calls gosched()
6. schedule() deschedules the goroutine:
maxcpu=1, mcpu=1, grunning=0
7. schedule() call getnextandunlock() which
fails to pick up the goroutine again,
because canaddcpu() fails, because mcpu==maxcpu
8. then it sees that grunning==0,
reports deadlock and terminates
