Many recently issued certificates are chained: there's one or more
intermediate certificates between the host certificate and the root CA
certificate. This change causes the code to load any number of
certificates from the certificate file. This matches the behaviour of
common webservers, and the output of OpenSSL's command line tools.

If a multi-line raw string is the first token on a line, it
should not be indented because the following lines (belonging
to the raw string) are not indented either.

* due to Issue 1466 the Msghdr struct for
 src/pkg/syscall/ztypes_darwin_386.go
 src/pkg/syscall/ztypes_darwin_amd64.go

* ztypes_*.go files for linux, freebsd and darwin

While the total increase is a dozen lines per file
the diff is larger due to a change to godefs,

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.

* Don't forget to flush the line buffer.
