2d48f3a029 client: send error events if update check or ping fails
Does not report errors when sending events since that would be cyclic.

41143a9d17 client: define error codes and events used by update_engine
Event error codes are application specific but for the sake of
simplicity lets re-use the update_engine ones where applicable.

update_engine and thus CoreUpdate only use a small subset of possible
event types so we can provide pre-defined event structs for them.

03222d488c client: support sending events asynchronously
Makes blocking and waiting for success/error optional, also allows
concurrent use of the rest of the client while events are sent.

ad277db627 client: implement event, ping, and updatecheck
For simplicity one request is sent for each event/ping/check for each
application. In the future it would be wise to batch together multiple
events and multiple applications to avoid excessive chatter.

afab572db3 protocol: change IsMachine flag to int

9a796427d5 omaha: distinguish zero and unset in ping active days field
Unlike the other fields unset here would mean unknown rather than "0" so
we must distinguish between the two. In the end it isn't very
significant since our update server and none of our clients use these
self-reported active times, exclusively using when pings were received.

4d02220019 omaha: add basic but functional omaha server for testing
This server doesn't care about app id, versions, or really anything.
Once a payload has been set it will use it for all update requests.

e5eb9eb583 omaha: implement server based on OmahaHandler
As-is this server cannot do much and must be given an Updater
implementation to handle requests. Server.Mux is exposed to in case the

5e54ada1e9 omaha: add structure for representing a single app update
The protocol structures are intended for representing a collection of
apps and their updates but for a server's internal API and data store we
need to represent a self-contained app update manifest.

75a1125f53 omaha: split request and response structures
Despite having common names between the request and response XML
structures the actual values which may appear in them are completely
disjoint. Splitting the types up makes the protocol easier to understand
when reading the code. When applicable, required fields like status are
passed to Add* methods.

ec70842bdd omaha: rework/cleanup protocol APIs
- Avoid long argument lists and only pass values that are strictly
   required such as status, fill in all other fields directly instead.
 - Fill OS struct in requests based on local system.
 - Define event and status codes as constants.
 - Misc style tweaks.

fef283aeb6 omaha: remove XMLName from nested structures
The special XMLName field is only useful in the top level structs which
need something to attach the lower case tag to. On the rest the default
behavior without XMLName works just fine so it is clutter.

The datastore tags have been dropped too since they are not needed.
