The source of these errors is undiagnosed, but they have only been
observed on netbsd builders (on a variety of architectures).
Tested manually by injecting this code into the test's handler:
if mrand.Intn(4) == 0 {
if conn, _, err := w.(Hijacker).Hijack(); err == nil {
conn.(*net.TCPConn).SetLinger(0)
conn.Close()
return
}
}
and temporarily disabling the 'runtime.GOOS' part of the condition.

Adds a new, cryptobyte based, CRL parser, which returns a
x509.RevocaitonList, rather than a pkix.CertificateList. This allows us
to return much more detailed information, as well as leaving open the
option of adding further information since RevocationList is not a
direct ASN.1 representation like pkix.CertificateList. Additionally
a new method is added to RevocationList, CheckSignatureFrom, which is
analogous to the method with the same name on Certificate, which
properly checks that the signature is from an issuing certiifcate.
This change also deprecates a number of older CRL related functions and
types, which have been replaced with the new functionality introduced
in this change:
* crypto/x509.ParseCRL
* crypto/x509.ParseDERCRL
* crypto/x509.CheckCRLSignature
* crypto/x509/pkix.CertificateList
* crypto/x509/pkix.TBSCertificateList

This change does four things:
* removes the chain cache
* during path building, equality is determined by checking if the
subjects and public keys match, rather than checking if the entire
certificates are equal
* enforces EKU suitability during path building
* enforces name constraints on intermediates and roots which have
SANs during path building
The chain cache is removed as it was causing duplicate chains to be
returned, in some cases shadowing better, shorter chains if a longer
chain was found first.
Checking equality using the subjects and public keys, rather than the
entire certificates, allows the path builder to ignore chains which
contain cross-signature loops.
EKU checking is done during path building, as the previous behavior
of only checking EKUs once the path had been built caused the path
builder to incorrectly ignore valid paths when it encountered a path
which would later be ruled invalid because of unacceptable EKU usage.
Name constraints are applied uniformly across all certificates, not
just leaves, in order to be more consistent.

cmd/dist may set and/or unset variables before building, and at any
rate it is fragile to run 'go install' before sourcing env.bat.
The build-stamp information embedded by the 'go' command is currently
sensitive to whether CGO_* variables are implicit or explicit, so running
'go install' before env.bat may cause stamped metadata to become stale.
(Explicitly setting to the default arguably ought to produce the same
metadata as leaving the variables unset, but that's a separate issue
and a bigger cleanup.)
Moreover, run.bat is supposed to parallel run.bash, and run.bash
already hasn't invoked 'go install' itself since CL 6531!

Fix by delaying the "comparable" error check until we encounter

Note for the future: reflect makes it unnecessarily clumsy
