This step was added in CL 188738 to work around the issue
golang.org/issue/33443. That issue has now been resolved,
so this step is no longer needed and can be removed.

Signing with RSA-PSS can uncover faulty crypto.Signer implementations,
and it can fail for (broken) small keys. We'll have to take that
breakage eventually, but it would be nice for it to be opt-out at first.
TLS 1.3 requires RSA-PSS and is opt-out in Go 1.13. Instead of making a
TLS 1.3 opt-out influence a TLS 1.2 behavior, let's wait to add RSA-PSS
to TLS 1.2 until TLS 1.3 is on without opt-out.
Note that since the Client Hello is sent before a protocol version is
selected, we have to advertise RSA-PSS there to support TLS 1.3.
That means that we still support RSA-PSS on the client in TLS 1.2 for
verifying server certificates, which is fine, as all issues arise on the
signing side. We have to be careful not to pick (or consider available)
RSA-PSS on the client for client certificates, though.
We'd expect tests to change only in TLS 1.2:
* the server won't pick PSS to sign the key exchange
(Server-TLSv12-* w/ RSA, TestHandshakeServerRSAPSS);
* the server won't advertise PSS in CertificateRequest
(Server-TLSv12-ClientAuthRequested*, TestClientAuth);
* and the client won't pick PSS for its CertificateVerify
(Client-TLSv12-ClientCert-RSA-*, TestHandshakeClientCertRSAPSS,
Client-TLSv12-Renegotiate* because "R" requests a client cert).
Client-TLSv13-ClientCert-RSA-RSAPSS was updated because of a fix in the test.
This effectively reverts 8834353072.
Testing was made more complex by the undocumented semantics of OpenSSL's
-[client_]sigalgs (see openssl/openssl#9172).

For later versions of MacOS, the dynamic loader is more picky about
enforcing restrictions on __DWARF MachO load commands/segments,
triggering aborts of the form
dyld: malformed mach-o image: segment __DWARF has vmsize < filesize
for Go programs that use cgo on Darwin. The error is being triggered
because the Go linker is setting "vmsize" in the DWARF segment entry
to zero as a way to signal that the DWARF doesn't need to be mapped
into memory at runtime (which we need to continue to do).
This patch changes the initial protection on the __DWARF segment to
zero, which dyld seems to be happy with (this is used for other similar
non-loadable sections such as __LLVM).

Previously, when we resolved a commit hash (not a complete version),
we always checked the contents of the module cache for any
pseudo-version matching that commit.
However, there are many possible names for a given commit. Generally
the semantically-highest valid name is the best, and that may change
over time as new tags are added, so if we are able to fetch a better
name from upstream we should do so. Otherwise, we should fall back to
the highest appropriate name found in the cache.

CL 46434 changed the doc for Server.IdleTimeout to include
falling back to Server.ReadHeaderTimeout if both
Server.IdleTimeout and Server.ReadTimeout are zero.
However, we explicitly set the ReadDeadlines firstly based
off Server.IdleTimeout or Server.ReadTimeout before attempting
to read the next request, thus the current doc is incorrect.
This CL reverts CL 46434 and also updates the doc for
Server.ReadHeaderTimeout to documenting falling back
to Server.ReadTimeout, if the former is zero, otherwise
there is no timeout.

There is a subtle distinction between a value
*being* the zero value vs being *equal to* the zero value.
This was discussed at length in #31450.
Using "a zero value" in the docs suggests that there may
be more than zero value. That is possible on the "equal to
zero value" reading, but not the "is zero" reading that we
selected for the semantics of IsZero.
This change attempts to prevent any confusion on this front by
switching to "the zero value" in the documentation.
And while we're here, eliminate a double-space.

This fixes a regression introduced in CL 180337. When we query a
module at "latest" that has no tagged versions, we tried to use ""
as the version because we used info.Name instead of info.Version. This
only happened when using a proxy: in direct mode, info.Name is set to
the underlying VCS revision, which is fine.
Also: serve "/mod/path/@latest" through our test proxy.
Previously, we served a 404, which made this bug hard to detect.

Currently, 'go get -u' and 'go get -u=patch' avoid accidentally
downgrading modules by preventing upgrades in two cases:
1) If the current version is a prerelease that is semantically later
than the "latest" or "patch" version.
2) If the current version is a pseudoversion that is chronologically
newer than the "latest" or "patch" version.
With this change, 'go get m@latest' and 'go get m@patch' prevent
downgrades using the same checks.
Also: 'go get m@patch' now works if m is a module path but not a
package path (i.e., there is no package in the module root directory).

It is too confusing to have to set GONOSUMDB and GONOPROXY
in common use cases, but one cannot be guaranteed to be a
subset of the other.
This CL adds GOPRIVATE, which takes the same kind of pattern list
but is defined as "these patterns are private (non-public) modules".
Today the implication is that GOPRIVATE is the default setting for
GONOSUMDB and GONOPROXY. If there are other accommodations
to make for private packages in the future or in other tools,
having this clear statement of intent will let us do that.
(For example maybe an IDE integration would hyperlink an import
path to godoc.org; consulting GOPRIVATE would be a reasonable
way to decide not to do that for certain imports. In contrast,
consulting GONOPROXY or GONOSUMDB clearly would not.)
