On (at least) macOS 10.12, the `security cms` subcommand used by the
iOS detection script will output an error to stderr. The command
otherwise succeeds, but the extra line confuses a later parsing step.
To fix it, use only stdout and ignore stderr from every command run
by detect.go.
For the new iOS builders.

X.509v1 certificates are ancient and should be dead. (They are even
prohibited by the Baseline requirements, section 7.1.1.)
However, there are a number of v1 roots from the 1990's that are still
in operation. Thus crypto/x509.Certificate.CheckSignatureFrom allows
X.509v1 certificates to sign other certificates.
The chain building code, however, only allows v1 certificates to sign
others if they're a root. This change adds a test to check that.

First steps towards defining type aliases in the spec.
This is a nomenclature clarification, not a language change.
The spec used all three terms 'embedded type', 'anonymous field',
and 'embedded field'. Users where using the terms inconsistently.
The notion of an 'anonymous' field was always misleading since they
always had a de-facto name. With type aliases that name becomes even
more important because we may have different names for the same type.
Use the term 'embedded field' consistently and remove competing
terminology.

Previously the following could happen, though in practice it would
be rare.
Goroutine 1:
(*Tx).QueryContext begins a query, passing in userContext
Goroutine 2:
(*Tx).awaitDone starts to wait on the context derived from the passed in context
Goroutine 1:
(*Tx).grabConn returns a valid (*driverConn)
The (*driverConn) passes to (*DB).queryConn
Goroutine 3:
userContext is canceled
Goroutine 2:
(*Tx).awaitDone unblocks and calls (*Tx).rollback
(*driverConn).finalClose obtains dc.Mutex
(*driverConn).finalClose sets dc.ci = nil
Goroutine 1:
(*DB).queryConn obtains dc.Mutex in withLock
ctxDriverPrepare accepts dc.ci which is now nil
ctxCriverPrepare panics on the nil ci
The fix for this is to guard the Tx methods with a RWLock
holding it exclusivly when closing the Tx and holding a read lock
when executing a query.

The runtime internal structField interprets name=="" as meaning anonymous,
but the exported reflect.StructField has always set Name, even for anonymous
fields, and also set Anonymous=true.
The initial implementation of StructOf confused the internal and public
meanings of the StructField, expecting the runtime representation of
anonymous fields instead of the exported reflect API representation.
It also did not document this fact, so that users had no way to know how
to create an anonymous field.
This CL changes StructOf to use the previously documented interpretation
of reflect.StructField instead of an undocumented one.
The implementation of StructOf also, in some cases, allowed creating
structs with unexported fields (if you knew how to ask) but set the
PkgPath incorrectly on those fields. Rather than try to fix that, this CL
changes StructOf to reject attempts to create unexported fields.
(I think that may be the right design choice, not just a temporary limitation.
In any event, it's not the topic for today's work.)
