Glibc uses some special signals for special thread operations. These
signals will be used in programs that use cgo and invoke certain glibc
functions, such as setgid. In order for this to work, these signals
need to not be masked by any thread. Before this change, they were
being masked by programs that used os/signal.Notify, because it
carefully masks all non-thread-specific signals in all threads so that a
dedicated thread will collect and report those signals (see ensureSigM
in signal1_unix.go).
This change adds the two glibc special signals to the set of signals
that are unmasked in each thread.
Fixes#12498.

The one in misc/makerelease/makerelease.go is particularly bad and
probably warrants rotating our keys.
I didn't update old weekly notes, and reverted some changes involving
test code for now, since we're late in the Go 1.5 freeze. Otherwise,
the rest are all auto-generated changes, and all manually reviewed.
