	import (
		"vector" -> "container/vector"
		"ast" -> "go/ast"
		"sha1" -> "hash/sha1"
		etc.
	)

and update Makefiles.  Because I did the conversion
semi-automatically, I sorted all the import blocks
as a post-processing.  Some files have therefore
changed that didn't strictly need to.

Rename local packages to lower case.
The upper/lower distinction doesn't work on OS X
and complicates the "single-package directories
with the same package name as directory name"
heuristic used by gobuild and godoc to create
the correlation between source and binary locations.
Now that we have a plan to avoid globally unique
names, the upper/lower is unnecessary.

The renamings will cause trouble for a few users,
but so will the change in import paths.
This way, the two maintenance fixes are rolled into
one inconvenience.

for example, if building in src/lib/container,
objects go in obj/container/, so that 6g -Iobj
will find "container/vector".

install packages in hierarchy in $GOROOT.

this change only updates gobuild.
another change will have to update all
the sources to refer to "container/vector" etc
and regenerate all the Makefiles.

there are some pretty lame functions here
(e.g., Mkdir, Remove, the Getenv("PWD"))
but i will implement better ones in another CL.

as a reminder, the old conversion
was that you could write

	var arr [10]byte;
	var slice []byte;
	slice = arr;

but now you have to write

	slice = &arr;

the change eliminates an implicit &, so that
the only implicit &s left are in the . operator
and in string(arr).

also, removed utf8.EncodeRuneToString
in favor of string(rune).

older reflection syntax, without the "func", is still
