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.

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

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.

R=rsc

lib/template updated to use new setup; its clients also updated.

Step 2 will make os's error support internally much cleaner.

	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.
