As is, they were fully vulnerable to the Lucky13 attack. The SHA1
variants implement limited countermeasures (see f28cf8346c4) but the
SHA256 ones are apparently used rarely enough (see 8741504888b) that
it's not worth the extra code.
Instead, disable them by default and update the warning.

In Go 1.0, the Config struct consisted only of exported fields.
In Go 1.1, it started to grow private, uncopyable fields (sync.Once,
sync.Mutex, etc).
Ever since, people have been writing their own private Config.Clone
methods, or risking it and doing a language-level shallow copy and
copying the unexported sync variables.
Clean this up and export the Config.clone method as Config.Clone.
This matches the convention of Template.Clone from text/template and
html/template at least.

Named returned values should only be used on public funcs and methods
when it contributes to the documentation.
Named return values should not be used if they're only saving the
programmer a few lines of code inside the body of the function,
especially if that means there's stutter in the documentation or it
was only there so the programmer could use a naked return
statement. (Naked returns should not be used except in very small
functions)
This change is a manual audit & cleanup of public func signatures.
Signatures were not changed if:
* the func was private (wouldn't be in public godoc)
* the documentation referenced it
* the named return value was an interesting name. (i.e. it wasn't
simply stutter, repeating the name of the type)
There should be no changes in behavior. (At least: none intended)

While reviewing uses of the lower-level Client API in code, I found
that in many cases, code was using Client only because it needed a
timeout on the connection. DialWithDialer allows a timeout (and
other values) to be specified without resorting to the low-level API.

This moves the various CA root fetchers from crypto/tls into crypto/x509.
The move was brought about by issue 2997. Windows doesn't ship with all
its root certificates, but will instead download them as-needed when using
CryptoAPI for certificate verification.
This CL changes crypto/x509 to verify a certificate using the system root
CAs when VerifyOptions.RootCAs == nil. On Windows, this verification is
now implemented using Windows's CryptoAPI. All other root fetchers are
unchanged, and still use Go's own verification code.
The CL also fixes the hostname matching logic in crypto/tls/tls.go, in
order to be able to test whether hostname mismatches are honored by the
Windows verification code.
The move to crypto/x509 also allows other packages to use the OS-provided
root certificates, instead of hiding them inside the crypto/tls package.
Fixes#2997.

This change moves a number of common PKIX structures into
crypto/x509/pkix, from where x509, and ocsp can reference
them, saving duplication. It also removes x509/crl and merges it into
x509 and x509/pkix.
x509 is changed to take advantage of the big.Int support that now
exists in asn1. Because of this, the public/private key pair in
http/httptest/server.go had to be updated because it was serialised
with an old version of the code that didn't zero pad ASN.1 INTEGERs.

Many recently issued certificates are chained: there's one or more

Previously we checked the certificate chain from the leaf
upwards and expected to jump from the last cert in the chain to
a root certificate.
Although technically correct, there are a number of sites with
problems including out-of-order certs, superfluous certs and
missing certs.
The last of these requires AIA chasing, which is a lot of
complexity. However, we can address the more common cases by
using a pool building algorithm, as browsers do.
We build a pool of root certificates and a pool from the
server's chain. We then try to build a path to a root
certificate, using either of these pools.
This differs from the behaviour of, say, Firefox in that Firefox
will accumulate intermedite certificate in a persistent pool in
the hope that it can use them to fill in gaps in future chains.
We don't do that because it leads to confusing errors which only
occur based on the order to sites visited.
This change also enabled SNI for tls.Dial so that sites will return
the correct certificate chain.
