Previously, multi-byte characters were not allowed. Also certain single-byte
characters, such as '-', were disallowed.
Fixes#3813.

Includes gofix module. The only case not covered should be
xml.Unmarshal, since it remains with a similar interface, and
would require introspecting the type of its first argument
better.

This CL improves the xml package in the following ways:
- makes its interface match established conventions
- brings Marshal and Unmarshal closer together
- fixes a large number of bugs and adds tests
- improves speed significantly
- organizes and simplifies the code
Fixes#2426.
Fixes#2406.
Fixes#1989.
What follows is a detailed list of those changes.
- All matching is case sensitive without special processing
to the field name or xml tag in an attempt to match them.
Customize the field tag as desired to match the correct XML
elements.
- Flags are ",flag" rather than "flag". The names "attr",
"chardata", etc, may be used to name actual XML elements.
- Overriding of attribute names is possible with "name,attr".
- Attribute fields are marshalled properly if they have
non-string types. Previously they were unmarshalled, but were
ignored at marshalling time.
- Comment fields tagged with ",comment" are marshalled properly,
rather than being marshalled as normal fields.
- The handling of the Any field has been replaced by the ",any"
flag to avoid unexpected results when using the field name for
other purposes, and has also been fixed to interact properly
with name paths. Previously the feature would not function
if any field in the type had a name path in its tag.
- Embedded struct support fixed and cleaned so it works when
marshalling and also when using field paths deeper than one level.
- Conflict reporting on field names have been expanded to cover
all fields. Previously it'd catch only conflicts of paths
deeper than one level. Also interacts correctly with embedded
structs now.
- A trailing '>' is disallowed in xml tags. It used to be
supported for removing the ambiguity between "attr" and "attr>",
but the marshalling support for that was broken, and it's now
unnecessary. Use "name" instead of "name>".
- Fixed docs to point out that a XMLName doesn't have to be
an xml.Name (e.g. a struct{} is a good fit too). The code was
already working like that.
- Fixed asymmetry in the precedence of XML element names between
marshalling and unmarshalling. Marshal would consider the XMLName
of the field type before the field tag, while unmarshalling would
do the opposite. Now both respect the tag of the XMLName field
first, and a nice error message is provided in case an attempt
is made to name a field with its tag in a way that would
conflict with the underlying type's XMLName field.
- Do not marshal broken "<???>" tags when in doubt. Use the type
name, and error out if that's not possible.
- Do not break down unmarshalling if there's an interface{} field
in a struct.
- Significant speed boost due to caching of type metadata and
overall allocation clean ups. The following timings reflect
processing of the the atom test data:
Old:
BenchmarkMarshal 50000 48798 ns/op
BenchmarkUnmarshal 5000 357174 ns/op
New:
BenchmarkMarshal 100000 19799 ns/op
BenchmarkUnmarshal 10000 128525 ns/op

The allowed conversions before and after are:
type Tstring string
type Tbyte []byte
type Trune []rune
string <-> string // ok
string <-> []byte // ok
string <-> []rune // ok
string <-> Tstring // ok
string <-> Tbyte // was illegal, now ok
string <-> Trune // was illegal, now ok
Tstring <-> string // ok
Tstring <-> []byte // ok
Tstring <-> []rune // ok
Tstring <-> Tstring // ok
Tstring <-> Tbyte // was illegal, now ok
Tstring <-> Trune // was illegal, now ok
Update spec, compiler, tests. Use in a few packages.
We agreed on this a few months ago but never implemented it.
Fixes#1707.

This is Go 1 package renaming CL #1.
This one merely moves the source; the import strings will be
changed after the next weekly release.
The only edits are in Makefiles.
