a94d7df2cb go/analysis/internal/checker: don't clobber fact when codeFact fails
`codeFact` returns `nil, err` on errors, which results in error messages like:

    panic: internal error: encoding of nil fact failed in [analyzer]

Though that and the stacktrace are often enough to identify the cause, the nil
hides the actual source of the problem.

db798565ff go/analysis/passes/test: remove some false positives
Alternative build systems like blaze don't always provide a way to determine
the relationship between a package and the package it's testing. This means
that sometimes the check for misspelled Example function names over-reports
because it doesn't find the object being exemplified. Don't report errors
unless a object can't be found in any of the imports. This means that there
won't be any false positives though of course this comes at the cost of
false positives.

36c10c0a62 x/tools/go/packages: seems to do nothing when given non-Go files
This CL fixes packages ignoring errors regarding files that have
non .go extensions. Packages can be called with just file names
or path which includes files. These aren't checked at all by
packages if they are go files or not, but it fails silently because
of it.

In more detail, go list fails with named files error in STDERR.
However, that is ignored, because go list notoriously abused STDERR
for non-error messages.

Fixes golang/go#29899

b6b7807791 go/analysis: make stdmethods happy on encoding/xml
Historically, vet had always been unhappy about encoding/xml itself:

	method MarshalXML(e *xml.Encoder, start xml.StartElement) error should
		have signature MarshalXML(*xml.Encoder, xml.StartElement) error

This dates back to the time when vet couldn't depend on type
information. It compared the type expressions directly as strings, which
was a problem when the code was in encoding/xml itself. There, the
function parameters are *Encoder and StartElement, not *xml.Encoder and
xml.StartElement.

However, vet has been depending on type information for a while, so this
restriction no longer makes sense. The analyzer almost got it right, but
the only stopgap was a piece of the old code that tried to compare type
expression strings.

Remove it; typeString already deals with these edge cases for us. To
ensure vet remains happy with encoding/xml, add a very simple test for
it. The package now has zero reports, so the fact that its source has
zero "// want" comments is appropriate.

Finally, remove some long unused parameters from matchParamType.

2f43c6d1a2 internal/span: change to private fields
Change span to hide its fields and have validating accessors
This catches the cases where either the offset or the position is being used
when it was not set.
It also normalizes the forms as the API now controls them, and allows us to
simplify some of the logic.
The converters are now allowed to return an error, which lets us cleanly
propagate bad cases.
The lsp was then converted to the new format, and also had some error checking
of its own added on the top.
All this allowed me to find and fix a few issues, most notably a case where the
wrong column mapper was being used during the conversion of definition results.

6a988fd03a tools/cmd/gopls: modify gopls to use automatcally generated types
Gopls presently uses hand-coded data types (in internal/lsp/protocol)
for communicating with LSP clients. Instead, modify it to use the
automatically generated file (internal/lsp/protocol/tsprotocol.go).

Replaced files have been put (temporarily) in a directory 'preserve'
so readers can compare the old data types with the new ones.

00c44ba9c1 internal/lsp: add cache for type information
This change adds an additional cache for type information, which here is
just a *packages.Package for each package. The metadata cache maintains
the import graph, which allows us to easily determine when a package X
(and therefore any other package that imports X) should be invalidated.

Additionally, rather than performing content changes as they happen, we
queue up content changes and apply them the next time that any type
information is requested.

6a08e3108d playground: use stdlib instead of appengine packages
With modern versions of App Engine, it's no longer needed to use the
google.golang.org/appengine/... packages.

Package log from standard library can be used instead of the
google.golang.org/appengine/log package. Packages net/http and
context from standard library can be used instead of
google.golang.org/appengine/urlfetch.

This simplifies the code and reduces the number of dependences.

Start using the golangorgenv package from previous commit to
make the decision of whether to enforce sharing restrictions,
rather than relying on the appengine build tag. The appengine
build tag is no longer set in App Engine Standard with Go 1.11+
runtime. An alternative solution would be detect App Engine by
doing something like:

	// GAE_ENV environment variable is set to "standard" in App Engine environment, Go 1.11 runtime.
	// See https://cloud.google.com/appengine/docs/standard/go111/runtime#environment_variables.
	var onAppengine = os.Getenv("GAE_ENV") == "standard"

But we choose to upgrade to explicit app-scoped environment variable
configuration as part of this change. It provides better security
properties, and the value of adding an intermediate transitional step
is not high enough to justify doing it.

When getting the value of "X-AppEngine-Country" header, use its
canonical format "X-Appengine-Country" to avoid an allocation.
This does not change behavior.

Run go mod tidy (using Go 1.12).

bd17c084df godoc/env: replace with golangorgenv
This change replaces the env package with a new golangorgenv package.

The previous env package existed primarily to configure the godoc
instance that was running golang.org. By now, the golang.org website
has been factored out to x/website, which has its own env package,
but ends up still using this env package indirectly via x/tools/godoc.

The goal of this change is to make env available for other services
that run on subdomains of golang.org, so they can continue to safely
rely on the x/tools/playground, which will be modified in the next
commit to also use the new golangorgenv.

The golangorgenv package replaces the IsProd function with a more
specific one. Start using it in packages x/tools/{,cmd}/godoc. Also,
re-arrange the order of checks to give the host suffix check higher
priority than the environment variable check. This way, if the
environment variable isn't set, the host suffix check gets a chance
to run.

When getting the value of "X-AppEngine-Country" header, use its
canonical format "X-Appengine-Country" to avoid an allocation.
This does not change behavior.

69e0dcfa11 internal/lsp: cache package metadata to minimize calls to packages.Load
Instead of calling packages.Load on every character change, we reparse
the import declarations of the file and determine if they have
changed. We also introduce a metadata cache that caches the import
graph. This is used in type-checking and only updated on calls to
packages.Load.

It is difficult to debug gopls in combination with the incremental

seems like the incremental changes can sometimes produce strange
behavior. Disable it for now until we can prioritize work on it.
