This change adds the outline of the implementation of the workspace mode.
The go command will now locate go.work files, and read them to determine
which modules are in the workspace. It will then put those modules in
the root of the workspace when building the build list. It supports
building, running, testing, and listing in workspaces. There are still
many TODOs for undone work and other changes to fix certain cases. Some
of these undone parts include: replaces and go.work.sum files, as well
as go mod {test,why,verify}, excludes in workspaces, updating work files
to include module names in comments and setting the GOWORK variable.

mainPackagesOnly now includes non-main packages matched by literal
arguments in the returned slice, since their errors must be reported.
GoFilesPackages attaches the same error to its package if
opts.MainOnly is true. This changes the error output of 'go run'
slightly, but it seems like an imporovement.

This change does context propagation (and only context propagation)
necessary to add context to modfetch.Download and pkg.LoadImport.
This was done by adding context to their callers, and then
adding context to all call-sites, and then repeating adding
context to callers of those enclosing functions and their
callers until none were left. In some cases the call graph expansion
was pruned by using context.TODOs.
The next CL will add a span to Download. I kept it out of this
change to avoid making it any larger (and harder to review)
than it needs to be.

Action.Func is now a func(*Builder, context.Context, *Action), so that
contexts can be propagated into the action funcs. While context
is traditionally the first parameter of a function, it's the second
parameter of Action.Func's type to continue to allow for methods
on Builder to be used as functions taking a *Builder as the first
parameter. context.Context is instead the first parameter on
those functions.

'GOFLAGS=-mod=vendor' currently causes 'go get' to always fail unless
the '-mod' flag is explicitly overwritten. Moreover, as of CL 198319
we plan to set -mod=vendor by default if a vendor directory is
present, so all users with vendor directories will be affected — not
just those who set 'GOFLAGS' explicitly.
Similarly, an explicit '-mod=readonly' argument to 'go get' is
currently ignored as a special case, but the fact that it is ignored
(rather than rejected) can be very surprising.
Rather than adding more special cases, we should remove the '-mod'
flag from 'go get' entirely.

The current "go mod" command does too many things.
The design is unclear.
It looks like "everything you might want to do with modules"
which causes people to think all module operations go through
"go mod", which is the opposite of the seamless integration we're
going for. In particular too many people think "go mod -require"
and "go get" are the same.
It does make sense to put the module-specific functionality
under "go mod", but not as flags. Instead, split "go mod" into
multiple subcommands:
go mod edit # old go mod -require ...
go mod fix # old go mod -fix
go mod graph # old go mod -graph
go mod init # old go mod -init
go mod tidy # old go mod -sync
go mod vendor # old go mod -vendor
go mod verify # old go mod -verify
Splitting out the individual commands makes both the docs
and the implementations dramatically easier to read.
It simplifies the command lines
(go mod -init -module m is now 'go mod init m')
and allows command-specific flags.
We've avoided subcommands in the go command to date, and we
should continue to avoid adding them unless it really makes
the experience significantly better. In this case, it does.
Creating subcommands required some changes in the core
command-parsing and help logic to generalize from one
level to multiple levels.
As part of having "go mod init" be a separate command,
this CL changes the failure behavior during module initialization
to be delayed until modules are actually needed.
Initialization can still happen early, but the base.Fatalf
is delayed until something needs to use modules.
This fixes a bunch of commands like 'go env' that were
unhelpfully failing with GO111MODULE=on when not in a
module directory.

Fixes #26581.
Fixes #26596.

To date, go run has required a list of .go files.
This CL allows in place of that list a single import path
or a directory name or a pattern matching a single patckage.
This allows 'go run pkg' or 'go run dir', most importantly 'go run .'.
The discussion in #22726 gives more motivation.
The basic idea is that you can already run 'go test .'
but if you're developing a command it's pretty awkward
to iterate at the same speed. This lets you do that,
by using 'go run . [args]'.
Fixes #22726.

Everything got a bit tangled together in b.action1.
Try to tease things apart again.
In general this is a refactoring of the existing code, with limited
changes to the effect of the code.
The main additional change is to complete a.Deps for link actions.
That list now directly contains all the inputs the linker will attempt
to read, eliminating the need for a transitive traversal of the entire
action graph to find those. The comepleteness of a.Deps will be
important when we eventually use it to decide whether an cached
action output can be reused.
all.bash passes, but it's possible I've broken some subtety of
buildmode=shared again. Certainly that code took the longest
to get working.
