13e4359083 update_engine_events.go: Add a custom "InstallStarted" event. 
This can help us to know how many clusters have clicked "start upgrade",
plus those in automatic mode.

d946c1e7b2 client: disable checking for ping and event status in responses 
Turns out CoreUpdate does not currently send <ping status="ok"> and
<event status="ok"> in responses like the protocol says it should.

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.

73e12a0154 client: add support for machine-wide omaha clients 
Uses machine id and boot id for user and session respectively, matching
the existing behavior of update_engine.

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 
This flag is a boolean "0" or "1", with "0" as the default so keeping
the "omitempty" xml option is ok.

036aedf2d7 protocol: remove stray Event type 
The Event struct was split into EventRequest and EventResponse back in
75a1125f but the older now unused type was never deleted.

a6290c1b4f protocol: add ParseRequest and ParseResponse functions 
For parsing and verification of of HTTP request and response bodies,
including optional checking the Content-Type field which the handler
previously didn't do.

5f9a499a46 package: fix SHA256 attribute name, now defined by the spec. 
The old name was my own extension and unused by anything so there aren't
any compatibility issues here.

79e582819b protocol: sort xml attributes 
A cosmetic change, though this will change the order in the XML output.
The spec lists fields alphabetically so this makes comparison easier.

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
server needs to additional handlers for serving package payloads, etc.

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.

f208691b12 omaha: stop wrapping URL slice in a struct 
Since splitting request and response structs it is no longer necessary
to work around Go's awkard handling of a `xml:"urls>url"` tag.

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.
