The error returned by convertUntyped is 'cannot convert _ to _', which
can be misleading in contexts where an explicit conversion would be
allowed.
Arguably the error message from convertUntyped should just be 'cannot
use _ as _', as 'convert' has an explicit meaning within the spec.
Making that change caused a large number of test failures, so for now we
just fix this for assignments by interpreting the error.

This change rejects module paths that don't conform to

unpublished modules with unpublishable paths, and we don't

Next, before this change, when go mod init is run in GOPATH,
it would try to use the location of the directory within GOPATH

that inferred module path if it conforms to module.CheckPath.

The go command now recognizes 'retract' directives in go.mod. A
retract directive may be used by a module author to indicate a
version should not be used. The go command will not automatically
upgrade to a retracted version. Retracted versions will not be
considered when resolving version queries like "latest" that don't
refer to a specific version.
Internally, when the go command resolves a version query, it will find
the highest release version (or pre-release if no release is
available), then it will load retractions from the go.mod file for
that version. Comments on retractions are treated as a rationale and
may appear in error messages. Retractions are only loaded when a query
is resolved, so this should have no impact on performance for most
builds, except when go.mod is incomplete.

Query and other functions now accept an "allowed" function that
returns an error (previously, the function returned a bool). If the
error is equivalent to ErrDisallowed, it indicates the version is
excluded (or, in a future CL, retracted). This provides predicates a
chance to explain why a version is not allowed.
When a query refers to a specific revision (by version, branch, tag,
or commit name), most callers will not use the Allowed predicate. This
allows commands like 'go list -m' and 'go mod download' to handle
disallowed versions when explicitly requested. 'go get' will reject
excluded versions though.
When a query does not refer to a specific revision (for example,
"latest"), disallowed versions will not be considered.
When an "allowed" predicate returns an error not equivalent to
ErrDisallowed, it may be ignored or returned, depending on the
case. This never happens for excluded versions, but it may happen for
retractions (in a future CL). This indicates a list of retractions
could not be loaded. This frequently happens when offline, and it
shouldn't cause a fatal or warning in most cases.

In order to generate more accurate or informative error messages from
the type checker, it can be helpful to interpret error messages in
context. This is currently achieved in a number of ways:
+ Return a boolean value, and then reverse-engineer the error at the
callsite (as in representable->representableConst).
+ Return a value causing the error (as in Checker.missingMethod), and
add the error at the callsite.
+ Pass a "reason" string pointer to capture the error (as in
Checker.assignableTo), and add the error at the callsite.
+ Pass a "context" string pointer, and use this when writing errors in
the delegated method.
In all cases, it is the responsibility of whatever code calls
Checker.error* to set the operand mode to invalid.
These methods are used as appropriate, depending on whether multiple
errors are generated, whether additional context is needed, and whether
the mere presence of an error needs to be interpreted at the callsite.
However, this practice has some downsides: the plurality of error
handling techniques can be a barrier to readability and composability.
In this CL, we introduce Yet Another Pattern, with the hope that it can
replace some or all of the existing techniques: factor out side-effect
free functions that evaluate a single error, and add helpers for
recording this error in the Checker.
As a proof of concept this is done for Checker.representable and
Checker.convertUntyped. If the general pattern does not seem appropriate
for replacing some or all of the error-handling techniques listed above,
we should revert to an established technique.
Some internal error APIs are refactored to operate on an error, rather
than a types.Error, with internal error metadata extracted using
errors.As. This seemed to have negligible impact on performance, but we
should be careful about actually wrapping errors: I expect that many
users will expect err to be a types.Error.

The StripPrefix wrapper strips a prefix string from the request's
URL.Path field, but doesn't touch the RawPath field. This leads to the
confusing situation when StripPrefix handles a request with URL.RawPath
populated (due to some escaped characters in the request path) and the
wrapped request's RawPath contains the prefix but Path does not.
This change modifies StripPrefix to strip the prefix from both Path and
RawPath. If there are escaped characters in the prefix part of the
request URL the stripped handler serves a 404 instead of invoking the
underlying handler with a mismatched Path/RawPath pair.
This is a backward incompatible change for a very small minority of
requests; I would be surprised if anyone is depending on this behavior,
but it is possible. If that's the case, we could make a more
conservative change where the RawPath is trimmed if possible, but when
the prefix contains escaped characters then we don't 404 but rather send
through the invalid Path/RawPath pair as before.

Once go:notinheap types cannot be in either place, we don't need to
consider pointers to such types to be pointers, at least according to
the garbage collector and stack copying. (This is the big win of this

Previously, this cache was a member of the (ephemeral) modload.loader
struct. However, the Go language version for a given module version
does not vary based on the build list, the set of loaded packages, the
build tags in use, the meaning of the "all" pattern, or anything else
that can be configured for an instance of the package loader. The map
containing that information is therefore not appropriate as a field of
the (configurable, package-list-dependent) loader struct.
The Go language version mapping could, in theory, be read from the
go.mod file in the module cache (or replacement directory) every time
it is needed: this map is just a cache, and as such it belongs
alongside the other caches and indexes in the modload package, which
are currently found in modfile.go.
We may want to do the same sort of global caching for the mapping from
each module.Version to its list of direct requirements (which are
similarly idempotent), but for now that is left for a future change.

Previously, when we encountered an excluded version in any module's
requirements, we would resolve it to the next higher version.
Unfortunately, the meaning of “the next higher version” can change
over time.
Moreover, users who use 'exclude' directives normally either already
require some higher version (using the 'exclude' directive to prune
out invalid requirements from some intermediate version), or already
require some lower version (using the 'exclude' directive to prevent
'go get -u' from upgrading to a known-bad version). In both of these
cases, resolving an upgrade for the excluded version is needless work
even in the best case: it adds work for the 'go' command when there is
already a perfectly usable selected version of the module in the
requirement graph.
Instead, we now interpret the 'exclude' directive as dropping all
references to the excluded version.
This implements the approach described in
https://golang.org/issue/36465#issuecomment-572694990.

This allows semver-based comparisons of the version without additional allocations.
Also comment on the reason for the loops that iterate over modFile instead.
(I was reading the vendor code in order to add the lazy-loading version check,
and this section was a bit unclear to me.)

Sets Content-Length:0 for nil bodies in PATCH requests, as we already do for POST and PUT requests.
RFC 2616 mentions that unless a method’s Content-Length is forbidden it can send one.
In the wild, we’ve found that Microsoft Azure’s DataLake Gen2 storage API https://docs.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/update deliberately rejects PATCH requests without a Content-Length, yet there is no workaround for setting that header when trying to flush the content of a file which was uploaded in a previous request.

Due to a typo, this test case was not actually exercising the bug
described in golang/go#33656. Update it to do so. Interestingly, the
comparison is now valid (as it should be) -- I suspect #33656 is
actually fixed.

These exported functions are mostly trivial wrappers, but do make
certain assumptions about how the underlying Checker APIs can be called.
Add some simple tests.
