The -json and -c=N flags, formerly belonging only to the

The no-op -source, -v, -all, and -tags flags, formerly belonging only

common to all checkers.
The -flags flag now reports all registered flags (except the

This CL publishes the former internal/unitchecker package.
Its misnamed Main function is renamed Run, and it has a new Main

The motivation for this change is to reduce cmd/vet-lite to the point

Vet issues a warning (non-error diagnostic) when, for example, it
cannot check an assembly file because the Go and asm symbols are in
different packages. The new analysis API has no concept of warnings:
any diagnostic always causes a non-zero exit.
This change turns the asmdecl diagnostics back into warnings using
log.Print, which is not ideal, but is necessary to pacify cmd/vet/all
and its whitelist during the transition. Better solutions would be for
the new analysis API to have a concept of warning, or for asmdecl to
be silent and cmd/vet/all's whitelist not to expect these messages.
Also, fix a bug in the "cross-check" predicate: cmd/vet confuses the
name of a package and its path. The a∕b∕c names (using Unicode
division slash) that appear in assembly correspond directly to the
path.
The only effective test of this change will be cmd/vet/all itself.

The cgocall analyzer was originally written in vet to analyze "raw" cgo files,
which are type-checked on a best-effort basis. However, the go/analysis
API presents analyzers with "cooked" cgo files, which are well-typed
legal Go but obscure the relationship between a call C.f(...) and its arguments.
Prior to this CL, cgocall attempted to "uncook" the file, which was
as predictably fragile as it sounds, and it rapidly broke as the cgo
recipe evolved.
This change causes cgocall to parse, modify, type-check and analyze "raw"

is rather too clever but should be more robust than the one it replaces.

This change makes AddNamedImport more symmetrical to DeleteNamedImport
in behavior, signature, and documentation.
In Go, it is valid to import a package (identified by an import path)
with different names in a single .go file¹. For example, this is ok,
and the program will build as long as there are no unused imports²:
import (
"path"
. "path"
_ "path"
pathpkg "path"
)
The four imports (represented by ast.ImportSpec type) have the same
import path, but different names.
It's currently possible to use DeleteNamedImport to delete the exact
{name, import path} ast.ImportSpec from an AST.
Previously, it wasn't possible to use AddNamedImport to add an exact
{name, import path} ast.ImportSpec if the AST already has another
ast.ImportSpec with the same import path (but different name).
This change fixes that, making it possible to use AddNamedImport as
expected.
Rename the ipath parameter to path in AddNamedImport for consistency
with DeleteNamedImport. Also change the language used in its
documentation to be more precise and consistent with DeleteNamedImport.
Add test cases for this behavior. The DeleteNamedImport test cases
were passing before any changes to the astutil code.
