Prior to this change package "foo" had to be installed in order to check
example names in "foo_test" package.
However by the time "foo_test" package is checked a parsed "foo" package
has been already constructed. Use it to check example names.
Also change TestDivergentPackagesExamples test to pass directory of the
package to the vet tool as it is the most common way to invoke it. This
requires changes to errchk to add support for grabbing source files from
a directory.
Fixes#16189

The way that -all works was unclear from the documentation and made
worse by recent changes to the flag package. Improve matters by making
the help message say "default true" for the tests that do default to true,
and tweak some of the wording.
Before:
Usage of vet:
vet [flags] directory...
vet [flags] files... # Must be a single package
For more information run
go doc cmd/vet
Flags:
-all
enable all non-experimental checks (default unset)
-asmdecl
check assembly against Go declarations (default unset)
...
After:
Usage of vet:
vet [flags] directory...
vet [flags] files... # Must be a single package
By default, -all is set and all non-experimental checks are run.
For more information run
go doc cmd/vet
Flags:
-all
enable all non-experimental checks (default true)
-asmdecl
check assembly against Go declarations (default true)

-test flag is a testing only flag that enables all vet checks. It was needed
because there was no way to run all vet checks in a single command
invocation. However it is possible to do this now by combining -all and -shadow
flags.
Also a recently added -tests flag is similarly named, having both -test and
-tests can be confusing.

This commit modifies the style of a error message in case of -shadow.
Previously such a message would look like:
foo.go:42: declaration of err shadows declaration at shadow.go:13:
Changes of the commit include highlighting the variable name and
removing the ": "(space intended) at the end of the line:
foo.go:42: declaration of "err" shadows declaration at shadow.go:13
Fixes#14585.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

This means bringing over the examples flag and sorting doc.go.
Subsequent changes will generalize the examples flag to a general
test naming flag, but let's start with the original code.
No more changes to golang.org/x/tools please. This should not have
happened (and letting it happen was partly my fault).

The next change will adjust the source to use std

This may (temporarily) break the build; the next
commit (immediately following) will fix it. We do
it in two commits so that we can see the manual
changes.

This is a simple refactoring of main.go that will enable the type checker
to be used during vetting.
The change has an unimportant effect on the arguments: it now assumes
that all files named explicitly on the command line belong to the same
package. When run by the go command, this was true already.
Also restore a missing parenthesis from an error message.
