5fea2ccc77 all: single space after period.
The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

This CL doesn't use go/doc to parse. It only addresses // comments.
It was generated with:

$ perl -i -npe 's,^(\s*// .+[a-z]\.)  +([A-Z]),$1 $2,' $(git grep -l -E '^\s*//(.+\.)  +([A-Z])')
$ go test go/doc -update

519474451a all: make copyright headers consistent with one space after period
This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.

Go policy has been single space after periods in comments for some time.

The copyright header template at:

    https://golang.org/doc/contribute.html#copyright

also uses a single space.

Make them all consistent.

880a689124 runtime: don't call msanread when running on the system stack
The runtime is not instrumented, but the calls to msanread in the
runtime can sometimes refer to the system stack.  An example is the call
to copy in stkbucket in mprof.go.  Depending on what C code has done,
the system stack may appear uninitialized to msan.

5174df9087 runtime, runtime/msan: add msan runtime support
These are the runtime support functions for letting Go code interoperate
with the C/C++ memory sanitizer.  Calls to msanread/msanwrite are now
inserted by the compiler with the -msan option.  Calls to
msanmalloc/msanfree will be from other runtime functions in a subsequent
CL.
