Use HEADER_IO macro from gopack to read archive header
The HEADER_IO macro portably reads archive headers. The
current arsize code fails in the case of archive headers produced
on plan 9 6c and read on other systems (it's not portable).
Modify lex.c to use the portable macro
Build tested (including tests) on OSX.

There are three classes of methods/functions called Error:
a) The Error method in the just introduced error interface
b) Error methods that create or report errors (http.Error, etc)
c) Error methods that return errors previously associated with
the receiver (Tokenizer.Error, rows.Error, etc).
This CL introduces the convention that methods in case (c)
should be named Err.
The reasoning for the change is:
- The change differentiates the two kinds of APIs based on
names rather than just on signature, unloading Error a bit
- Err is closer to the err variable name that is so commonly
used with the intent of verifying an error
- Err is shorter and thus more convenient to be used often
on error verifications, such as in iterators following the
convention of the sql package.

This partially undoes 8fd7e6d070c8, but preserves its semantics.
More importantly, it results in the data about each fix being
decentralised, which makes it easier for new fixes to be added,
and other gofix users to slot new fixes in.
It also adds some useful metadata that could be used in the future.

To make the error fix more useful, expand typecheck to gather
more information about struct fields, typecheck range statements,
typecheck indirect and index of named types, and collect information
about assignment conversions.
Also, change addImport to rename top-level uses of a to-be-imported
identifier to avoid conflicts. This duplicated some of the code in
the url fix, so that fix is now shorter.

Back then, every x.go file in a package became an x.6 file
in the archive. It was important to be able to allow the
use of long Go source file names, hence the increase in size.
Today, all Go source files compile into a single _go_.6 file
regardless of their names, so the archive file name length
no longer needs to be long. The longer name causes some
problems on Plan 9, where the native archive format is the
same but with 16-byte names, so revert back to 16.

Got rid of all the magic mystery globals. Now
for %N, %T, and %S, the flags +,- and # set a sticky
debug, sym and export mode, only visible in the new fmt.c.
Default is error mode. Handle h and l flags consistently with
the least side effects, so we can now change
things without worrying about unrelated things
breaking.

goinstall has built in support for a few common code hosting sites. The
identification of which vcs tool should be used was based purely on a
regex match against the provided import path. The problem with this
approach is that it requires distinct import paths for different vcs
tools on the same site.
Since bitbucket has recently starting hosting Git repositories under the
same bitbucket.org/user/project scheme as it already hosts Mercurial
repositories, now would seem a good time to take a more flexible
approach.
We still match the import path against a list of regexes, but now the
match is purely to distinguish the different hosting sites. Once the
site is identified, the specified function is called with the repo and
path matched out of the import string. This function is responsible for
creating the vcsMatch structure that tells us what we need to download
the code.
For github and launchpad, only one vcs tool is currently supported, so
these functions can simply return a vcsMatch structure. For googlecode,
we retain the behaviour of determing the vcs from the import path - but
now it is done by the function instead of the regex. For bitbucket, we
use api.bitbucket.org to find out what sort of repository the specified
import path corresponds to - and then construct the appropriate vcsMatch
structure.

Change the name of cas() in cc to newcase() to avoid a NIX conflict.
cas() is used in cc to create a new Case struct. There is a name
conflict in that cas() is a commonly-used
name for compare and swap. Since cas() is only used internally
in the compiler in 3 places, change the name to avoid a wider
conflict with the NIX runtime. This issue might well come up on
other OSes in the future anyway, as the name is fairly common.

API question: is a scanner token an int or a rune?
Since the rune is the common case and the token values
are the special (negative) case, I chose rune. But it could
easily go the other way.

Gotest has special flags like -file that are somewhat
