c5038c8593 exp/html: ignore self-closing flag except in SVG and MathML
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.

Pass 1 additional test.

c48b77b1b5 all: make Unicode surrogate halves illegal as UTF-8
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.

5f7bec693d image/jpeg: send a correct Start Of Scan (SOS) header.
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

I won't address this issue.

a108369c83 syscall: return EINVAL when string arguments have NUL characters
Since NUL usually terminates strings in underlying syscalls, allowing
it when converting string arguments is a security risk, especially
when dealing with filenames. For example, a program might reason that
filename like "/root/..\x00/" is a subdirectory or "/root/" and allow
access to it, while underlying syscall will treat "\x00" as an end of
that string and the actual filename will be "/root/..", which might
be unexpected. Returning EINVAL when string arguments have NUL in
them makes sure this attack vector is unusable.
