Added a 'location' property to RequestException, analogous to the 'location' property of wrapped nsIExceptions, so that tracebacks can be made for the exceptions if needed.

As you can see, I've added log messages whenever the Generator's 'cb' property is accessed--this is almost guaranteed to be very close to a 'yield' statement, and therefore provides us with a decently accurate idea of where the generator 'stopped'. We also log a message when the generator continues, and by doing so we get an idea of how the coroutines interleave.
Another idea I had was to actually match calls to self.cb with calls to 'yield' to automatically detect e.g. two yields in a row (which will ordinarily result in a generator 'hanging'), a generator exiting while a self.cb still hasn't been called, but I'm not sure what kinds of reprecussions it may have.
* async generators: much better stack traces
* dav: use global identity system rather than login/logout to manage
usernames and passwords.
* dav: there is a checkLogin() instead of login() which can be used to
verify auth at any time.
* dav: make it so that we can (only internally atm) hold multiple
locks for different URLs.
* identity: add an identity manager singleton service to keep
identities globally, referenced by a name, with aliasing support (so
e.g., dav can ask for the 'dav' identity, while something else can
alias 'dav' to another identity).
* service: keep track of logged in status here, rather than in the dav
service. Use the global id manager.
* Logging improvements / default log levels tweaked. Less chatty now.
Ability to tweak log levels of individual loggers via prefs.
* Various crypto module fixes, specially for RSA.
* 'service' lock removed, reuses server lock now. dav module supports
temporarily blocking locks to simulate the 'service' lock (login()
needs this, since dav is not configured at that time).
* PKI support: data encryption uses randomly-generated symmetric keys,
which are then encrypted with RSA public keys and stored on the
server.
