notes:
* due to Issue 1466 the Msghdr struct for
src/pkg/syscall/ztypes_darwin_386.go
src/pkg/syscall/ztypes_darwin_amd64.go
had to be edited after the godefs generation.
* ztypes_*.go files for linux, freebsd and darwin
have been prepared on the correct host OS and ARCH.
While the total increase is a dozen lines per file
the diff is larger due to a change to godefs,
http://code.google.com/p/go/source/detail?r=c79e30afe9c8
while has altered the names of Pad members which
causes gofmt to realign the affected structs

This change makes it legal to pass a struct value as receiver
outside the package declaring the struct even if the respective
struct type has non-exported fields.
This is a backwards-compatible language change motivated by the
fact that it is already possible to circumvent the assignment
restriction when calling methods through interfaces (see issue
1402).

This enables #cgo directives to contain a os/arch
specification which restricts the definition of
the given option to matching systems.
For example:
#cgo amd64 CFLAGS: -DAMD64=1
#cgo linux CFLAGS: -DLINUX=1
#cgo linux/amd64 CFLAGS: -DLINUX_ON_AMD64=1

The object files begin with a header that is
$GOARCH
on a line by itself. This CL changes that header to
go object $GOOS $GOARCH release.2011-01-01 4567+
where the final two fields are the most recent release
tag and the current hg version number.
All objects imported into a Go compilation or linked into an
executable must have the same header line, and that header
line must match the compiler and linker versions.
The effect of this will be that if you update and run all.bash
and then try to link in objects compiled with an earlier version
of the compiler (or invoke the wrong version of the compiler),
you will get an error showing the different headers instead
of perhaps silent incompatibility.
Normal usage with all.bash should be unaffected, because
all.bash deletes all the object files in $GOROOT/pkg/$GOOS_$GOARCH
and cleans all intermediate object files before starting.
This change is intended to diagnose stale objects arising when
users maintaining alternate installation directories forget to
rebuild some of their files after updating.
It should help make the adoption of $GOPATH (CL 3780043)
less error-prone.

Prior to this CL, there were two requirements about the
package name main.
1. The package that sits at the root of the import graph
(the one where program execution begins)
must be named main.
2. No other package in the program can be named main.
This CL only removes requirement #2, which can be done
without changing any other Go documentation.
The new wording and formatting is such that removing
requirement #1 can be done by deleting a single line,
but making that change is explicitly outside the scope
of this CL, because it would require changes to other
documentation at the same time.

Since nobody suggested major changes to the higher level API, I'm
splitting up the lower level code for review. This is the first of the
changes for the packet reading/writing code.
It deliberately doesn't include a Makefile because the package is
incomplete.

* Don't require lines to be full.
* Don't forget to flush the line buffer.
* Update the test so that it doesn't happen to include only full lines
in order to test the above.
* Always write the line after the header as GNUPG expects it.

OpenPGP changed its OCFB mode for more modern packets (for example, the
MDC symmetrically encrypted packet). This change adds a bool to
determine which mode is used.

GC is still single-threaded.
Multiple threads will happen in another CL.
Garbage collection pauses are typically
about half as long as they were before this CL.

The timestamp file is being created before cgo
runs, which means errors will not prevent it
from being created and thus will cause the
build to break by rendering the rule up-to-date
when it isn't.

Follow morestack, so that crashes during a stack split
give complete traces. Also mark stack segment boundaries
as an aid to debugging.
Correct various line number bugs with yet another attempt
at interpreting the pc/ln table. This one has a chance at
being correct, because I based it on reading src/cmd/ld/lib.c
instead of on reading the documentation.
Fixes#1138.
Fixes#1430.
Fixes#1461.

If the same directory was used for multiple builds,
it was possible for a stale version.go to contain the
wrong definitions for $GOOS and $GOARCH, because
they can change even if the hg version does not.
Split into multiple files to fix.

Shame on me: I fixed the same bug in 6l in 8691fcc6a66e
(https://golang.org/cl/2609041) and neglected
to look at 5l and 8l to see if they were affected.
On the positive side, the check I added in that CL is the
one that detected this bug.
Fixes#1457.

These are syntactical changes to better reflect the communication
operator's new status in the language.
- sending to a channel is now done via a send statement
- there is no binary communication operation anymore which
leads to a reduction of the number of precedence levels
from 6 to 5 (yeah!)
- small semantic change: since a send operation is not part
of the expression syntax anymore, a <- send operator is
binding weaker than any other operator now
- receiving from a channel is done as before via the unary
receive expression
- communication clauses in select statement now can contain
send statements or receive expressions
