When client fails to write a request is sends caller that error,
however server might have failed to read that request in the mean
time and replied with that error. When client then reads the
response the call would no longer be pending, so call will be nil
Handle this gracefully by discarding such server responses

The documentation says so, but in the case of a normalized
integral Rat, the denominator was a new value. Changed the
internal representation to use an Int to represent the
denominator (with the sign ignored), so a reference to it
can always be returned.
Clarified documentation and added test cases.

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.

Introduce a new bit flag SHIDDEN and bit mask SMASK to handle hidden

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.

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.
