3601f27708 godoc: make id attributes unique
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.

Fixes #3851.

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);

Fixes #3916.

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.

89d40b911c exp/locale/collate: changed API of Builder to be more convenient
for dealing with CLDR files:
- Add now taxes a list of indexes of colelems that are variables. Checking and
  handling is now done by the Builder.  VariableTop is now also properly generated
  using the Build method.
- Introduced separate Builder, called Tailoring, for creating tailorings of root
  table.  This clearly separates the functionality for building a table based on
  weights (the allkeys* files) versus tables based on LDML XML files.
- Tailorings are now added by two calls instead of one: SetAnchor and Insert.
  This more closely reflects the structure of LDML side and simplifies the
  implementation of both the client and library side.  It also preserves
  some information that is otherwise hard to recover for the Builder.
- Allow the LDML XML element extend to be passed to Insert.  This simplifies
  both client and library implementation.
