71c1a7b777 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

13a59b8c6d math/big: implement JSON un/marshaling support for Ints
Also: simplified some existing tests.

No support for Rats for now because the precision-preserving
default notation (fractions of the form a/b) is not a valid
JSON value.

4f7c33cd5a 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.

576d648b2a cmd/ld, cmd/6l, cmd/8l, cmd/5l: fix hidden/local symbol import for ELF systems
Introduce a newsym() to cmd/lib.c to add a symbol but don't add
them to hash table.
   Introduce a new bit flag SHIDDEN and bit mask SMASK to handle hidden
and/or local symbols in ELF symbol tables. Though we still need to order
the symbol table entries correctly.

15436da232 crypto/md5: faster inner loop, 3x faster overall
The speedup is a combination of unrolling/specializing
the actual code and also making the compiler generate better code.

Go 1.0.1 (size: 1239 code + 320 data = 1559 total)
md5.BenchmarkHash1K   1000000	   7178 ns/op	 142.64 MB/s
md5.BenchmarkHash8K    200000	  56834 ns/op	 144.14 MB/s

Partial unroll  (size: 1115 code + 256 data = 1371 total)
md5.BenchmarkHash1K   5000000	   2513 ns/op	 407.37 MB/s
md5.BenchmarkHash8K    500000	  19406 ns/op	 422.13 MB/s

Complete unroll  (size: 1900 code + 0 data = 1900 code)
md5.BenchmarkHash1K   5000000	   2442 ns/op	 419.18 MB/s
md5.BenchmarkHash8K    500000	  18957 ns/op	 432.13 MB/s

Comparing Go 1.0.1 and the complete unroll (this CL):

benchmark               old MB/s     new MB/s  speedup
md5.BenchmarkHash1K       142.64       419.18    2.94x
md5.BenchmarkHash8K       144.14       432.13    3.00x

On the same machine, 'openssl speed md5' reports 441 MB/s
and 531 MB/s for our two cases, so this CL is at 90% and 80% of
those speeds, which is at least in the right ballpark.
OpenSSL is using carefully engineered assembly, so we are
unlikely to catch up completely.

Measurements on a Mid-2010 MacPro5,1.

f26d61731d 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.

ccd63c3c19 net/http: non-keepalive connections close successfully
Connections did not close if Request.Close or Response.Close was true. This meant that if the user wanted the connection to close, or if the server requested it via "Connection: close", the connection would not be closed.

Fixes #1967.

ec099b2bc7 exp/locale/collate: implementation of main collation functionality for
key and simple comparisson. Search is not yet implemented in this CL.
Changed some of the types of table_test.go to allow reuse in the new test.
Also reduced number of primary values for illegal runes to 1 (both map to
the same).
