os: on GNU/Linux use waitid to avoid wait/kill race
On systems that support the POSIX.1-2008 waitid function, we can use it
to block until a wait will succeed. This avoids a possible race
condition: if a program calls p.Kill/p.Signal and p.Wait from two
different goroutines, then it is possible for the wait to complete just
before the signal is sent. In that case, it is possible that the system
will start a new process using the same PID between the wait and the
signal, causing the signal to be sent to the wrong process. The
Process.isdone field attempts to avoid that race, but there is a small
gap of time between when wait returns and isdone is set when the race
can occur.
This CL avoids that race by using waitid to wait until the process has
exited without actually collecting the PID. Then it sets isdone, then
waits for any active signals to complete, and only then collects the PID.
No test because any plausible test would require starting enough
processes to recycle all the process IDs.

syscall: call setgroups for no groups on GNU/Linux
Skip setgroups only for one particular case: GidMappings != nil and
GidMappingsEnableSetgroup == false and list of supplementary groups is
empty.
This patch returns pre-1.5 behavior for simple exec and still allows to
use GidMappings with non-empty Credential.

misc/cgo/test: fix issue9400 test on android/386
The test for #9400 relies on an assembler function that manipulates
the stack pointer. Meanwile, it uses a global variable for
synchronization. However, position independent code on 386 use a
function call to fetch the base address for global variables.
That function call in turn overwrites the Go stack.
Fix that by fetching the global variable address once before the
stack register manipulation.
Fixes the android/386 builder.

[dev.ssa] cmd/compile: decompose 64-bit integer on ARM
Introduce dec64 rules to (generically) decompose 64-bit integer on
32-bit architectures. 64-bit integer is composed/decomposed with
Int64Make/Hi/Lo ops, as for complex types.
where Add32carry returns a tuple (flags,uint32). Select0 and Select1
read the first and the second component of the tuple, respectively.
The two Add32carry will be CSE'd.
Similarly for multiplication, Mul32uhilo returns a tuple (hi, lo).
Also add support of KeepAlive, to fix build after merge.
Tests addressed_ssa.go, array_ssa.go, break_ssa.go, chan_ssa.go,
cmp_ssa.go, ctl_ssa.go, map_ssa.go, and string_ssa.go in
cmd/compile/internal/gc/testdata passed.
Progress on SSA for ARM. Still not complete.

cmd/compile: do not generate tail calls when dynamic linking on ppc64le
When a wrapper method calls the real implementation, it's not possible to use a
tail call when dynamic linking on ppc64le. The bad scenario is when a local
call is made to the wrapper: the wrapper will call the implementation, which
might be in a different module and so set the TOC to the appropriate value for
that module. But if it returns directly to the wrapper's caller, nothing will
reset it to the correct value for that function.

crypto/tls: buffer handshake messages.
This change causes TLS handshake messages to be buffered and written in
a single Write to the underlying net.Conn.
There are two reasons to want to do this:
Firstly, it's slightly preferable to do this in order to save sending
several, small packets over the network where a single one will do.
Secondly, since 37c28759ca46cf381a466e32168a793165d9c9e9 errors from
Write have been returned from a handshake. This means that, if a peer
closes the connection during a handshake, a “broken pipe” error may
result from tls.Conn.Handshake(). This can mask any, more detailed,
fatal alerts that the peer may have sent because a read will never
happen.
Buffering handshake messages means that the peer will not receive, and
possibly reject, any of a flow while it's still being written.
