morebuf holds a pc/sp from the last stack split or
reflect.call or panic/recover. If the pc is a closure,
the reference will keep it from being collected.
moreargp holds a pointer to the arguments from the
last stack split or reflect.call or panic/recover.
Normally it is a stack pointer and thus not of interest,
but in the case of reflect.call it is an allocated argument
list and holds up the arguments to the call.

The garbage collector can avoid scanning this section, with
reduces collection time as well as the number of false positives.
Helps a little bit with issue 909, but certainly does not solve it.

We should, after Go 1, make them work the same as
package xml, that is, make them appear in the outer
struct. For now turn them off so that people do not
depend on the old behavior.
Fixing them is issue 3069.

The m->cret word holds the C return value when returning
across a stack split boundary. It was not being cleared after
use, which means that the return value (if a C function)
or else the value of AX/R0 at the time of the last stack unsplit
was being kept alive longer than necessary. Clear it.
I think the effect here should be very small, but worth fixing
anyway.

When we build the encode engine for a recursive type, we
mustn't disregard the indirections or we can try to reuse an
engine at the wrong indirection level.

Fix by setting the element type if we discover it's zero while building.
We could have fixed this better with foresight by doing the id setting in a
different sequence, but doing that now would break binary compatibility.

I am making a unilateral decision here. I could also settle for returning 0,
as long it's documented, but I argue that it's equivalent to an index
out of bounds.

1, strip last path separator from $GOROOT
The user might define GOROOT=/path/to/go/, but then the dir
check in defaulttarg() will always complain the current dir
is not within $GOROOT/src/.
2, resolve symlinks in the default goroot
Or if getcwd() returns a fully-resolved path, the check in
defaulttarg() will always fail.

The set of errors forwarded by the os package varied with system and
was therefore non-portable.
Three helpers added for portable error checking: IsExist, IsNotExist, and IsPermission.
One or two more may need to come, but let's keep the set very small to discourage
thinking about errors that way.

Clang 3.1 has more warnings enabled by default than GCC.
Combined with -Werror, they cause the build to fail
unnecessarily. if the name of our compiler ends in "clang",
add the necessary extra -Wno options. Ideally we would add
these flags unconditionally, as GCC is supposed to ignore
unknown -Wno flags, but apple's llvm-gcc doesn't.

Periodically browse MHeap's freelists for long unused spans and release them if any.
Current hardcoded settings:
- GC is forced if none occured over the last 2 minutes.
- spans are handed back after 5 minutes of uselessness.
SysUnused (for Unix) is a wrapper on madvise MADV_DONTNEED on Linux and MADV_FREE on BSDs.

go/doc: move Examples to go/ast
cmd/go: use go/doc to read examples
src/pkg: update examples to use new convention
This is to make whole file examples more readable. When presented as a
complete function, preceding an Example with its output is confusing.
The new convention is to put the expected output in the final comment
of the example, preceded by the string "output:" (case insensitive).
An idiomatic example looks like this:
// This example demonstrates Foo by doing bar and quux.
func ExampleFoo() {
// example body that does bar and quux
// Output:
// example output
}

Also: Simplified handling of selector expressions. As a result, complicated
multi-line expressions containing selectors and calls/indices with arguments
broken accross lines don't get indented the same way as before, but the change
is minimal (see tests) and there's no such code in the std library. It seems
a worthwhile compromise given the much simpler code.
