cmd/internal/obj reconverted using rsc.io/c2go rev 40275b8.
All Prog*s need Ctxt field set so that the printer can tell
which architecture the Prog belongs to.
Use ctxt.NewProg consistently for this.

For new assembler, reconvert using rsc.io/c2go rev f9db76e.
- Removes trailing _ from Go keywords that are exported.
- Export regstr as Register, anames[5689] as Anames.
Also update clients.

These assemblers produce byte-for-byte identical output
to the ones written in C.
They are primarily a proof that cmd/internal/obj can be used
standalone to produce working object files. (The use via objwriter
starts by deserializing an already-constructed internal representation,
so objwriter does not exercise the code in cmd/internal/obj that
creates such a representation from scratch.)

This is the raw output of c2go. It needs fixes to make it compile.
Rather than make c2go do a 100% conversion (like we're doing for
liblink and the Go compilers), since this is so trivial I'm going to
make the remaining changes by hand in a followup CL.
This CL makes the next CL's diffs useful.
Also copy unmodified .y files (5a/a.y → new5a/a.y and so on)
The converted 6a/lex.c has been written to new6a/lex.go
but also to internal/asm/asm.go, because I'm going to factor
out some common code rather than convert it four times.

Using rsc.io/c2go repo revision 60c9302.
- Export a few symbols needed by assemblers.
- Implement Getgoroot etc directly, and add Getgoversion.
- Removes dependency on Go 1.4 go/build.
- Change magic history name <no name> to <pop>
The <pop> change requires adjustment to the liblink serializer.

This CL adds the real cmd/internal/obj packages.
Collectively they correspond to the liblink library.
The conversion was done using rsc.io/c2go's run script
at rsc.io/c2go repo version 706fac7.
This is not the final conversion, just the first working draft.
There will be more updates, but this works well enough
to use with go tool objwriter and pass all.bash.

cmd/internal/obj is the name for the Go translation of the C liblink library.
cmd/objwriter is the name of a Go binary that runs liblink's writeobj function.
When the bulk of liblink has been converted to Go but the assemblers and
compilers are still written in C, the C writeobj will shell out to the Go objwriter
to actually write the object file. This lets us manage the transition in smaller
pieces.
The objwriter tool is purely transitional.
It will not ship in any release (enforced in cmd/dist).
Adding a dummy program and some dummy imports here so that we
can work on the bootstrap mechanisms that will be necessary to build it.
Once the build process handles objwriter properly,
we'll work on the actual implementation.

debug/goobj is not ready to be published but it is
needed for the various binary-reading commands.
Move to cmd/internal/goobj.
(The Go 1.3 release branch deleted it, but that's not
an option anymore due to the command dependencies.
The API is still not vetted nor terribly well designed.)

Moving so that new Go 1.4 pprof can use it.
The old 'GNU objdump workalike' mode for 'go tool objdump'
is now gone, as are the tests for that mode. It was used only
by pre-Go 1.4 pprof. You can still specify an address range on
the command line; you just get the same output format as
you do when dumping the entire binary (without an address
limitation).

This removes a bunch of ugly duplicate code.
The end goal is to factor the disassembly code
into cmd/internal/objfile too, so that pprof can use it,
but one step at a time.

For Go 1.3 these external packages were collapsed into
large single-file implementations stored in the cmd/objdump
directory.
For Go 1.4 we want pprof to be able to link against them too,
so move them into cmd/internal, where they can be shared.
The new files are copied from the repo in the file path (rsc.io/...).
Those repos were code reviewed during development
(mainly by crawshaw and minux), because we knew the
main repo would use them.

To do in another CL: make cmd/objdump use cmd/internal/objfile too.
There is a package placement decision in this CL:
cmd/internal/objfile instead of internal/objfile.
I chose to put internal under cmd to make clear (and enforce)
that no standard library packages should use this
(it's a bit dependency-heavy).
