goc2c moves here.
parallel builds like old makefiles (-j4).
add clean command.
add banner command.
implement Go version check.
real argument parsing (same as 6g etc)

Windows changes will be a separate CL.

Thanks to Andrey Mirtchovski for tracking this down.

This was broken by CL 5528077 which removed the InsertSemis
flag from go/scanner - as a result, semicolons are now always
inserted and the respective indexer code checked for the
wrong token.

Replaced the code by a direct identifier test.

When slicing a slice, the bounds may be > len as long as they
are <= cap.  Interestingly, gccgo got that wrong and still
passed the testsuite and all the library tests.

This reduces the overhead necessary to work with OS-specific
file details, hides the implementation of FileStat, and
preserves the implementation-specific nature of Sys.

Expressions such as:

  stat.(*os.FileInfo).Sys.(*syscall.Stat_t).Uid
  fi1.(*os.FileStat).SameFile(fi2.(*os.FileStat))

Are now spelled as::

  stat.Sys().(*syscall.Stat_t).Uid
  os.SameFile(fi1, fi2)

I fixed types_linux.go yesterday but missed the others.

dist is short for distribution.  This is the new Go distribution tool.

The plan is to replace the Makefiles with what amounts to
'go tool dist bootstrap', although it cannot be invoked like
that since it is in charge of getting us to the point where we
can build the go command.

It will also add additional commands to replace bash scripts
like test/run (go tool dist testrun), eventually eliminating our
dependence on not just bash but all the Unix tools and all
of cygwin.

This is strong enough to build (cc *.c) and run (a.out bootstrap)
to build not just the C libraries and tools but also the basic
Go packages up to the bootstrap form of the go command
(go_bootstrap).  I've run it successfully on both Linux and Windows.
This means that once we've switched to this tool in the build,
we can delete the buildscripts.

This tool is not nearly as nice as the go tool.  There are many
special cases that turn into simple if statements or tables in
the code.  Please forgive that.  C does not enjoy the benefits
that we designed into Go.

I was planning to wait to do this until after Go 1, but the
Windows builders are both broken due to a bug in either
make or bash or both involving the parsing of quoted command
arguments.  Make thinks it is invoking

        quietgcc -fno-common -I"c:/go/include" -ggdb -O2 -c foo.c

but bash (quietgcc is a bash script) thinks it is being invoked as

        quietgcc -fno-common '-Ic:/go/include -ggdb' -O2 -c foo.c

which obviously does not have the desired effect.  Rather than fight
these clumsy ports, I accelerated the schedule for the new tool.
We should be completely off cygwin (using just the mingw gcc port,
which is much more standalone) before Go 1.

It is big for a single CL, and for that I apologize.  I can cut it into
separate CLs along file boundaries if people would prefer that.
