When generating replacement elements for an <isindex> tag, the old
addSyntheticElement method was producing the wrong nesting. Replace
it with parseImpliedToken.

If a tag doesn't have a closing '>', it isn't considered a tag;
it is just ignored and EOF is returned instead.

Pass one additional test in the test suite.

Change tokenizer tests to match correct behavior.

In HTML content, having a self-closing tag is a parse error unless
the tag would be self-closing anyway (like <img>). The only place a
self-closing tag actually makes a difference is in XML-based foreign
content.

The keyword reprents an untyped nil and is useful for
passing nil values to methods and functions. The
nil will be promoted to the appropriate type when
used; if a type cannot be assigned, an error results.

Surrogate halves are part of UTF-16 and should never appear in UTF-8.
(The rune that two combined halves represent in UTF-16 should
be encoded directly.)

Encoding: encode as RuneError.
Decoding: convert to RuneError, consume one byte.

This requires changing:
        package unicode/utf8
        runtime for range over string
Also added utf8.ValidRune and fixed bug in utf.RuneLen.

Fixes #3927.

Some browsers (e.g. IE9) ignore the case of 'id' attributes
which can lead to conflicts. Prefix non-generated 'id's with
"pkg-" to make them different from any generated attribute.

Also: Added missing entry for "Other packages" to top-level
index.

Section B.2.3 of http://www.w3.org/Graphics/JPEG/itu-t81.pdf discusses
the End of spectral selection (Se) byte.

Apparently many JPEG decoders ignore the Se byte (or let it through
with a warning), but some configurations reject them. For example,
http://download.blender.org/source/chest/blender_2.03_tree/jpeg/jcmaster.c
has these lines:

if (Ss != 0 || Se != DCTSIZE2-1 || Ah != 0 || Al != 0)
  ERREXIT1(cinfo, JERR_BAD_PROG_SCRIPT, scanno);

The 386 version has a performance regression, but as we have
