The new accessor requires passing a pointer to a user-allocated
MemStats structure.

Thanks to Andrey Mirtchovski for tracking this down.
This was broken by CL 5528077 which removed the InsertSemis
flag from go/scanner - as a result, semicolons are now always
inserted and the respective indexer code checked for the
wrong token.
Replaced the code by a direct identifier test.

This reduces the overhead necessary to work with OS-specific
file details, hides the implementation of FileStat, and
preserves the implementation-specific nature of Sys.
Expressions such as:
stat.(*os.FileInfo).Sys.(*syscall.Stat_t).Uid
fi1.(*os.FileStat).SameFile(fi2.(*os.FileStat))
Are now spelled as::
stat.Sys().(*syscall.Stat_t).Uid
os.SameFile(fi1, fi2)

Consequently, remove many package Makefiles,

gomake becomes 'go tool make'.
Turn off test phases of run.bash that do not work,
flagged with $BROKEN. Future CLs will restore these,

Merge package files in the go/ast MergePackageFiles

instead of map iteration order to obtain the same
package file each time. This functionality is used

- the main changes are removing the Doc suffix
from the exported types, so instead of
doc.TypeDoc one will have doc.Type, etc.
- All exported types now have a Name (or Names) field.
For Values, the Names field lists all declared variables
or constants.
- Methods have additional information about where they are
coming from.
- There's a mode field instead of a bool to
control the package's operation, which makes
it easier to extend w/o API changes.
Except for the partially implemented new Method type,
this is based on existing code. A clean rewrite is in
progress based on this new API.

- exports.go contains a stripped-down (but semantically unchanged)
version of the code in go/ast/filter.go for export filtering
- filter.go contains the documentation filtering code found before
at the end of doc.go; this is simply a code move w/o any semantic
changes
- godoc now relies on go/doc for export filtering when creating
documentation. It still has a separate form of export filtering
for showing the source code version. This needs to be consolidated
(perhaps the source form view should just be removed?).
- Stripping of function bodies (stripFunctionBodies function of
godoc.go) is now happening in doc.go (line 176).
- doc.NewPackageDoc has an extra parameter "exportsOnly. If set
to false, the behavior is as before. This function is only called
once in our source code; a gofix module is probably not warranted.
- Deleted doc.NewFileDoc - was never called.
This change is mostly a code move w/ some minimal tweaks. It should
not cause any changes to the behavior of godoc. It's a prerequisite
for extracting anonymous embedded fields.

An example for a method M() of type T can be written as

To differentiate between multiple examples for one function, type or

Example:
PACKAGE
package utf8
import "unicode/utf8"
Package utf8 implements functions and constants to support text
encoded in UTF-8. This package calls a Unicode character a rune for
brevity.
CONSTANTS
const (
RuneError = unicode.ReplacementChar // the "error" Rune or "replacement character".
RuneSelf = 0x80 // characters below Runeself are represented as themselves in a single byte.
UTFMax = 4 // maximum number of bytes of a UTF-8 encoded Unicode character.
)
Numbers fundamental to the encoding.
FUNCTIONS
func DecodeLastRune(p []byte) (r rune, size int)
DecodeLastRune unpacks the last UTF-8 encoding in p and returns the
rune and its width in bytes.
func DecodeLastRuneInString(s string) (r rune, size int)
DecodeLastRuneInString is like DecodeLastRune but its input is a
string.
func DecodeRune(p []byte) (r rune, size int)
DecodeRune unpacks the first UTF-8 encoding in p and returns the rune
and its width in bytes.
func DecodeRuneInString(s string) (r rune, size int)
DecodeRuneInString is like DecodeRune but its input is a string.
func EncodeRune(p []byte, r rune) int
EncodeRune writes into p (which must be large enough) the UTF-8
encoding of the rune. It returns the number of bytes written.
func FullRune(p []byte) bool
FullRune reports whether the bytes in p begin with a full UTF-8
encoding of a rune. An invalid encoding is considered a full Rune
since it will convert as a width-1 error rune.
func FullRuneInString(s string) bool
FullRuneInString is like FullRune but its input is a string.
func RuneCount(p []byte) int
RuneCount returns the number of runes in p. Erroneous and short
encodings are treated as single runes of width 1 byte.
func RuneCountInString(s string) (n int)
RuneCountInString is like RuneCount but its input is a string.
func RuneLen(r rune) int
RuneLen returns the number of bytes required to encode the rune.
func RuneStart(b byte) bool
RuneStart reports whether the byte could be the first byte of an
encoded rune. Second and subsequent bytes always have the top two
bits set to 10.
func Valid(p []byte) bool
Valid reports whether p consists entirely of valid UTF-8-encoded
runes.
func ValidString(s string) bool
ValidString reports whether s consists entirely of valid UTF-8-encoded
runes.
TYPES
type String struct {
// contains filtered or unexported fields
}
String wraps a regular string with a small structure that provides
more efficient indexing by code point index, as opposed to byte index.
Scanning incrementally forwards or backwards is O(1) per index
operation (although not as fast a range clause going forwards).
Random access is O(N) in the length of the string, but the overhead is
less than always scanning from the beginning. If the string is ASCII,
random access is O(1). Unlike the built-in string type, String has
internal mutable state and is not thread-safe.
func NewString(contents string) *String
NewString returns a new UTF-8 string with the provided contents.
func (s *String) At(i int) rune
At returns the rune with index i in the String. The sequence of runes
is the same as iterating over the contents with a "for range" clause.
func (s *String) Init(contents string) *String
Init initializes an existing String to hold the provided contents.
It returns a pointer to the initialized String.
func (s *String) IsASCII() bool
IsASCII returns a boolean indicating whether the String contains only
ASCII bytes.
func (s *String) RuneCount() int
RuneCount returns the number of runes (Unicode code points) in the
String.
func (s *String) Slice(i, j int) string
Slice returns the string sliced at rune positions [i:j].
func (s *String) String() string
String returns the contents of the String. This method also means the
String is directly printable by fmt.Print.
Fixes#2479.

This feature should make it easier to look at very large
directory trees.
- a new mode (URL: /pkg/?m=flat) shows directory listings w/o
indentation and entries with full path (html and text mode)
- in text mode, hierarchical (non-flat) directory listings are
now presented with indentation (/pkg/?m=text)
- in html mode, hierarchical (non-flat) directory listings are
presented with slightly less indentation
- there is an internal hook for programmatic control of the
display mode (for specialized versions of godoc).

This CL introduces the go.Example type and go.Examples functions that
are used to represent and extract code samples from Go source.
They should be of the form:
// Output of this function.
func ExampleFoo() {
fmt.Println("Output of this function.")
}
It also modifies godoc to read example code from _test.go files,
and include them in the HTML output with JavaScript-driven toggles.
It also implements testing of example functions with gotest.
The stdout/stderr is compared against the output comment on the
function.

sort.SortInts type. After patching this CL in and re-building go/doc
