cc3f21cefe spec: channel operations are restricted by the channel direction
Also:
- 'for' statements with a range clause do not accept send-only
   channels
- '_, _ = range ch' is not equivalent to "_ = range ch" if ch
   is a channel (rewriting the latter to the former leads to
   an invalid range clause).

These clarifications document the status quo.

3167c12eb2 cmd/dist: support building on debian/kFreeBSD
The debian/kFreeBSD project uses the FreeBSD kernel and the debian userspace. From our point of view, this is freebsd not linux as GOOS talks about the kernel syscall interface, not the userspace (although cgo alters that). As debian/kFreeBSD is experimental at this time, I do not think it is worth the effort of duplicating all the freebsd specific code so this is proposal represents a reasonable workaround.

Currently cgo is not supported, make.bash will detect this and disable cgo automatically during the build.

bcea0dd1d0 cmd/gc: fix inlining internal error with T.Method calls.
The compiler was confused when inlining a T.Method(f()) call
where f returns multiple values: support for this was marked
as TODO.

Variadic calls are not supported but are not inlined either.
Add a test preventively for that case.

Fixes #4167.

d7b0f2a524 math/rand: remove noop iteration in Perm
The first iteration always do `m[0], m[0] = m[0], m[0]`, because
`rand.Intn(1)` is 0.

fun note: IIRC in TAOCP version of this algorithm, `i` goes
backward (n-1->1), meaning that the "already" shuffled part of the
array is never altered betweens iterations, while in the current
implementation the "not-yet" shuffled part of the array is
conserved between iterations.

0ce96f9ef4 runtime: better stack traces in race reports
When a race happens inside of runtime (chan, slice, etc),
currently reports contain only user file:line.
If the line contains a complex expression,
it's difficult to figure out where the race exactly.
This change adds one more top frame with exact

28b599425d net: move deadline logic into pollServer
Update #4434.

The proposal attempts to reduce the number of places where fd,{r,w}deadline is checked and updated in preparation for issue 4434. In doing so the deadline logic is simplified by letting the pollster return errTimeout from netFD.Wait{Read,Write} as part of the wakeup logic.

The behaviour of setting n = 0 has been restored to match rev 2a55e349097f, which was the previous change to fd_unix.go before CL 6851096.

51b8edcb37 runtime: use reflect·call() to enter the function gc()
Garbage collection code (to be merged later) is calling functions
which have many local variables. This increases the probability that
the stack capacity won't be big enough to hold the local variables.
So, start gc() on a bigger stack to eliminate a potentially large number
of calls to runtime·morestack().

4228eb7915 log/syslog: correct message format
The syslog implementation was not correctly implementing the
traditional syslog format because it had a confused notion of
'priority'.  syslog priority is not a single number but is, in
fact, the combination of a facility number and a severity. The
previous Go syslog implementation had a single Priority that
appeared to be the syslog severity and no way of setting the
facility.  That meant that all syslog messages from Go
programs appeared to have a facility of 0 (LOG_KERN) which
meant they all appeared to come from the kernel.

Also, the 'prefix' was in fact the syslog tag (changed the
internal name for clarity as the term tag is more widely used)
and the timestamp and hostname values were missing from
messages.

With this change syslog messages are generated in the correct
format with facility and severity combined into a priority,
the timestamp in RFC3339 format, the hostname, the tag (with
the PID in [] appened) and the message.

The format is now:

   <PRI>1 TIMESTAMP HOSTNAME TAG[PID]: MSG

The TIMESTAMP, HOSTNAME and PID fields are filled in
automatically by the package. The TAG and the MSG are supplied
by the user. This is what rsyslogd calls TraditionalFormat and
should be compatible with multiple systems.
