51c83116a2 resources: Overhaul legacy code around the resource API
This patch makes a number of changes in the engine surrounding the
resource API. In particular:

* Cleanup of send/read event.
* Cleanup of DoSend (now Event) in the Watch method.
* Events are now more consistently pointers.
* Exiting within Watch is now done in a single place.
* Multiple incoming events will be combined into a single action.
* Events in flight during an action are played back after CheckApply.
* Addition of Close method to API

This gets things ready for rate limiting and semaphore metaparams!

This provides sensible defaults for when they're not the zero value.

44e7e0e970 resources: virt: Add missing converger call
This was previously left out accidentally I suppose.

45820b4ce3 resources: Rename Converger to ConvergerUID
This is more correct since we need the Converger method to return the
actual converger!

067932aebf resources: Remove SetWatching/IsWatching code from Watch
This removes some boilerplate from the Watch methods which can be baked
into the engine instead.

This code should be checked for races and locks to make sure we only
start resources when it makes sense to.

36b916f27f resources: Simplify resource Converger and Startup code
This takes the Converged initialization and Startup patterns that are
common in all resources, and bakes it into the core engine. This way
resource writing is much more concise and there is less boilerplate!

4803be1987 misc: Rename mgmtmain to lib and remove global package
This refactor should make it cleaner to use mgmt.

b0a8fc165c resources: Improve the state/cache system
Refactor the state cache into the engine. This makes resource writing
less error prone, and paves the way for better notifications.

to set the init for lxc containers.

2216c8dc1c virt: Do not restrict VIR_ERR_NO_DOMAIN to qemu.
Consider it sufficent that a libvirt.VIR_ERR_NO_DOMAIN was reported
without concerning ourselves over who reported it.

1370f2a76b gapi: Split out graph generation into a proper graph API
This is a monster patch that splits out the yaml and puppet based graph
generation and pushes them behind a common API. In addition alternate
pluggable GAPI's can be easily added! The important side benefit is that
you can now write a custom GAPI for embedding mgmt!

This also includes some slight clean ups that I didn't find it worth
splitting into separate patches.

75dedf391a virt: don't set emulator path
Remove the implicit emulator path from the domain definition. Libvirt is
already configured to use the correct emulator for kvm or qemu and
specifying it creates distro dependence.

Fixes #85

8381d8246a resources: virt: Add a virt resource based on libvirt
This adds an initial implementation of a virt resource based on libvirt.
It is not complete and requires more testing. The initial skeleton was
written by nseps but was not merged. It was later cleaned up and merged
in its current form by purpleidea. Many thanks to nseps for getting this
going, and hopefully we'll get you contributing more in the future!
