- delete utility files which contained functionality that is now elsewhere
(or saved the files away for now)
- cleanup Makefile (remove unnecessary deps)
- minor adjustments to godoc, fixed a couple of bugs
- make pretty.go self-contained

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
for incrementing, setting and getting those vars, as well as rendering all the
vars in a standard format.
Demonstrate the use of the exvar package in the http/triv server.

exact spec:
a) must be a multi-assignment w :=
b) a proper subset of the lhs
can be declared in same block
with the same type with no
"redeclaration" error

this allows gotest to find the locally built package when doing
make
gotest
without this option, one would have to say
make install
gotest
which kinda defeats the purpose
based on discussions with rsc.

Change the representation of errors in "os" to be cleaner.
(But they are not really representative of the power of the new scheme.)
Step 3 will be to remove all references to os.NewError.
Step 4 will be to delete the second half of lib/os/error.go.

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).
