Until now, errors which came with additional details (e.g., a declaration
cycle error followed by the list of objects involved in the cycle, one per
line) were reported as an ordinary error followed by "secondary" errors,
with the secondary errors marked as such by having a tab-indented error
message.
This approach often required clients to filter these secondary errors
(as they are not new errors, they are just clarifying a previously
reported error).
This CL introduces a new internal error_ type which permits accumulating
various error information that may then be reported as a single error.

Difference: errorf now accepts any value that implements
the poser interface in place of a position argument. All
types2 Objects implement poser.
type poser interface {
Pos() syntax.Pos
}

types2 and importer
This is a copy of the importer and types2 (unreviewed) prototype version
excluding the testdata directory containing tests (see below). Each file
is marked with the comment
// UNREVIEWED
on the first line. The plan is to check in this code wholesale (it runs and
passes all tests) and then review the code file-by-file via subsequent CLs
and remove the "// UNREVIEWED" comments as we review the files.
Since most tests are unchanged from the original go/types, the next CL will
commit those tests as they don't need to be reviewed again. (Eventually we
may want to factor them out and share them from a single place, e.g. the
test directory.)
The existing file fmtmap_test.go was updated.
