targets
This change replaces the Target variable that represents the main module
and the pathPrefix and inGorootSrc which provide other information about
the main module with a single MainModules value that represents multiple
main modules and holds their path prefixes, module roots, and whether
they are in GOROOT/src. In cases where the code checks Target or its
previously associated variables, the code now checks or iterates over
MainModules. In some cases, the code still assumes a single main module
by calling MainModules.MustGetSingleMainModule. Some of those cases are
correct: for instance, there is always only one main module for
mod=vendor. Other cases are accompanied with TODOs and will have to be
fixed in future CLs to properly support multiple main modules.
This CL (and other cls on top of it) are planned to be checked into a
branch to allow for those evaluating the workspaces proposal to try it
hands on.

If the go command is executed on Linux in a deleted directory,
it fails. This behavior is reasonable for commands which depend on
the CWD, but it's unexpected for commands like `go version`.
This change delays initialization of a global CWD variable.

Go commands show a warning message any time a pattern is expanded and a
symlink to a directory is encountered. For monorepo with non Go projects
using symlinks underneath, the output of go commands could be spammed by
this warning.
This commit includes the behavior change to only print this warning when
there's a pattern containing ... .

This change updates the lockedfile package to open files using the

This CL adds basic support for listing packages with overlays.
The new cmd/go/internal/fs package adds an abstraction for communicating
with the file system that will open files according to their overlaid paths,
and provides functions to override those in the build context to open
overlaid files. There is also some support for executing builds on packages
with overlays. In cmd/go/internal/work.(*Builder).build, paths are mapped
to their overlaid paths before they are given as arguments to tools.

While reviewing CL 228784, I noticed that various filepath.WalkFunc
implementations within cmd/go were dropping non-nil errors.
Those errors turn out to be significant, at least in some cases: for
example, they can cause packages to appear to be missing when any
parent of the directory had the wrong permissions set.
(This also turned up a bug in the existing list_dedup_packages test,
which was accidentally passing a nonexistent directory instead of the
intended duplicate path.)

To avoid confusion, also distinguish between packages and dirs in
search.Match results.
No test because this is technically only a performance optimization:
it would be very difficult to write such a test so that it would not
be flaky. (However, tested the change manually.)

methods
This change consolidates predicates currently scattered throughout
various parts of the package and module loader into methods on the
search.Match type.
That not only makes them more concise, but also encourages
consistency, both in the code and in reasoning about the kinds of
patterns that need to be handled. (For example, the IsLocal predicate
was previously two different calls, either of which could be easily
forgotten at a given call site.)

Since CL 194600, search.CleanPaths preserves characters after '@' in
each argument. This was done so that paths could be cleaned while
version queries were preserved. However, local and absolute file paths
may contain '@' characters.
With this change, '@' is treated as a normal character by
search.CleanPaths in local and absolute paths.

'go get' accepts arguments of the form path@version, and it passes
them through search.CleanPatterns before querying proxies. With this
change, CleanPatterns preserves text after '@' and will strip trailing
slashes from the patn.
Previously, we did not strip trailing slashes when a version was
present, which caused proxy base URL validation to fail. Module paths
that end with ".go" (for example, github.com/nats-io/nats.go) use
trailing slashes to prevent 'go build' and other commands from
interpreting packages as source file names, so this caused unnecessary
problems for them.

LoadPackage was used to load a *load.Package for a command line
argument, after pattern expansion. It provided two special cases on
top of LoadImport. First, it ensured that "cmd/" packages in GOROOT
were installed in "$GOROOT/bin" or "$GOROOT/pkg/tool". Second, it
translated absolute paths to packages in GOROOT and GOPATH into
regular import paths.
With this change, LoadImport now ensures "cmd/" packages have the
right Target (without the need for a special case) and
search.ImportPaths translates absolute paths.
LoadPackage no longer handles these special cases and has been renamed
to LoadImportWithFlags, since it's still useful for loading implicit
dependencies.

To date the go command has always just treated the command line
package patterns as a []string, expanded by pattern matching into
another []string. As a result, the code is not always clear about
whether a particular []string contains patterns or results.
A few different important bugs are caused by not keeping
this distinction clear enough. This CL sets us up well for fixing those,
by introducing an explicit search.Match struct holding the
results of matching a single pattern.
The added clarity here also makes it clear how to avoid duplicate
warnings about unmatched packages.
Fixes #26925. (Test in followup CL.)

People are (understandably) confused by creating go.mod files in GOPATH/src
and then having the go command not use modules in those directories.
We can't change that behavior (or we'll break non-module users of GOPATH)
but we can force 'go mod' (including 'go mod -init') to fail loudly in that case.
If this is not enough, the next step would be to print a warning every time
the go command is run in a GOPATH/src directory with a go.mod but
module mode hasn't triggered. But that will annoy all the non-module users.
Hopefully anyone confused will eventually run a 'go mod' command of
some kind, which will fail loudly.
Fixes #26365.
