cmd/api: add api/next.txt

This quiets all.bash noise for upcoming features we know about.

The all.bash warnings will now only print for things not in next.txt
(or in next.txt but not in the API).

Once an API is frozen, we rename next.txt to a new frozen file
(like go1.txt)

Fixes #3651

text/template: exec should accept interface value as valid.

Currently, if you pass some data to a template as an interface (e.g. interface{})
and extract that value that value as a parameter for a function, it fails, saying
wrong type.

This is because it is only looking at the interface type, not the interface content.

This CL uses the underlying content as the parameter to the func.

Fixes #3642.

go/parser: fix comment grouping (day 1 bug)

Comment groups must end at the end of a line (or the
next non-comment token) if the group started on a line
with non-comment tokens.

This is important for correct computation of "lead"
and "line" comments (Doc and Comment fields in AST nodes).

Without this fix, the "line" comment for F1 in the
following example:

type T struct {
     F1 int // comment1
     // comment2
     F2 int
}

is "// comment1// comment2" rather than just "// comment1".

This bug was present from Day 1 but only visible when
looking at export-filtered ASTs where only comments
associated with AST nodes are printed, and only in rare
cases (e.g, in the case above, if F2 where not exported,
godoc would show "// comment2" anyway because it was
considered part of the "line" comment for F1).

The bug fix is very small (parser.go). The bulk of the
changes are additional test cases (parser_test.go).

The fix exposed a caching bug in go/printer via one of the
existing tests, hence the changes to printer.go.

As an aside, the fix removes the the need for empty lines
before an "// Output" comment for some special cases of
code examples (e.g.: src/pkg/strings/example_test.go, Count
example).

No impact on gofmt formatting of src, misc.

Fixes #3139.

mime/multipart: fix handling of empty parts without CRLF before next part

Empty parts can be either of the form:

a) "--separator\r\n", header (w/ trailing 2xCRLF), \r\n "--separator"...
or
b) "--separator\r\n", header (w/ trailing 2xCRLF), "--separator"...

We never handled case b).  In fact the RFC seems kinda vague about
it, but browsers seem to do a), and App Engine's synthetic POST
bodies after blob uploads is of form b).

So handle them both, and add a bunch of tests.

(I can't promise these are the last fixes to multipart, especially
considering its history, but I'm growing increasingly confident at
least, and I've never submitted a multipart CL with known bugs
outstanding, including this time.)
