Now the default startup is that the program begins at _rt0_amd64_$GOOS,
which sets DI = argc, SI = argv and jumps to _rt0_amd64.

This makes the _rt0_amd64 entry match the expected semantics for
the standard C "main" function, which we can now provide for use when
linking against a standard C library.

This CL adds compatibility for GNU Emacs 23 (fixing fontification
issues) and XEmacs >=21.5.32 (fixing a lot of issues). Earlier
versions of XEmacs will not be supported because they do not
support POSIX character classes. Because of that, we also make use
of a lot of functions that were added in 21.5.32.

A known and currently unfixable issue with XEmacs is that go-mode
will not always fontify identifiers that use unicode correctly.

All changes for XEmacs are annotated in the diff.

Note: go--position-bytes is not currently used anywhere, but will
be in a future CL.

Fixes #4927.

Previously the HTTP client's (*Response).Body.Close would try
to keep reading until EOF, hoping to reuse the keep-alive HTTP
connection, but the EOF might never come, or it might take a
long time. Now we immediately close the TCP connection if we
haven't seen EOF.

This shifts the burden onto clients to read their whole response
bodies if they want the advantage of reusing TCP connections.

In the future maybe we could decide on heuristics to read some
number of bytes for some max amount of time before forcefully
closing, but I'd rather not for now.

Statistically, touching this code makes things regress, so I
wouldn't be surprised if this introduces new bugs, but all the
tests pass, and I think the code is simpler now too. Maybe.

Please test your HTTP client code before Go 1.1.

broke arm garbage collector

traceback_arm fails with a missing pc. It needs CL 7494043.
But that only makes the build break later, this time with
"invalid freelist". Roll back until it can be fixed correctly.

On OpenBSD 5.2, calling getsockname on an unbound Unix domain socket
results in a successful syscall, however the AF is unset and the length
is returned as zero. This has been changed to more portable behaviour,
which will be included in the OpenBSD 5.3 release.

For now, work around this by treating a successful getsockname() call
that returns a family of AF_UNSPEC and length of zero as a AF_UNIX
socket.

Makes TestPassFD work on OpenBSD 5.2.

Fixes #4956.

Implementation closely based on Russ' CL 7440047.

Future work: The error messages could be better
(e.g., instead of "missing return" it might say
"missing return (no default in switch)", etc.).

The only functional change is the new section
on terminating statements.

There is a minor syntax rewrite (not change)
of function declarations to make it easier to
refer to the notion of a function from all places
where it is used (function decls, method decls,
and function literals).

Includes some minor fixes/additions of missing links.

Based closely on Russ' proposal.
