2f284948af Remake exvar package to be more Go-ish. 
It now exports a Var interface (anyone can export their own custom var types now), so users need to create and manage their own vars and mark them as exportable via the Publish function. They are exposed via /debug/vars.

eac5db7f4c Copied 8g/6g into 5g. Used sharp tools to coax a .5 file out 
of 5g. 5l balks at the output and running 5g with -S shows
the true extent of the disaster. Still, better than
yesterday. Maybe.

Tested on the canonical:

package main

dc5cffbeb7 Use the mutex in exvar.Set since map access is not atomic. 
Imagine your var has a value of zero. If you have a goroutine calling Set(5),
and another calling Increment(+1), then you only want one of these outcomes:
  - Set completes first, and then Increment occurs => 6
  - Increment completes first, and then Set occurs => 5

However, you could get a sequence:
  - read (for Increment) 0
  - set (for Set) 5
  - write (for Increment) 1
This results in a value of 1, which is undesirable.

Kudos to dnadasi for catching this.

This handles integer-valued vars in a singleton struct, and exports functions

1f6463f823 Convert go tree to hierarchical pkg directory: 
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.

0f153ec6b4 build packages in obj/ subdirectory that mimics $GOROOT/pkg. 
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.

60ce95d7a1 code changes for array conversion. 
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).
