Needed to avoid a bug in OS X when a library was linked against
CoreFoundation without having it initialized in the main thread.

brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
I had to remove the THREADSAFE flag to make it work.
Couchdb seems the reason to use Spidermonkey at this point. Without these
changes Couchdb would crash hard when loading the Spidermonkey dylib.
If the threadsafety is required then we should look into making a keg-only
Spidermonkey for Couchdb's personal use.
The nspr dependency isn't documented as required, and doesn't seem to make a
difference if it is removed. So I removed it.

I squashed a number of commits here, and also replaced the use of nspr.prefix with HOMEBREW_PREFIX as in theory we are flexible with our requirement for dependencies, although with the limited build system that SpiderMonkey possesses this is difficult for us to achieve anyway…
