Batch hook pre- and post-receive calls (#8602)

* make notifyWatchers work on multiple actions

* more efficient multiple notifyWatchers

* Make CommitRepoAction take advantage of multiple actions

* Batch post and pre-receive results

* Set batch to 30

* Auto adjust timeout & add logging

* adjust processing message

* Add some messages to pre-receive

* Make any non-200 status code from pre-receive an error

* Add missing hookPrintResults

* Remove shortcut for single action

* mistaken merge fix

* oops

* Move master branch to the front

* If repo was empty and the master branch is pushed ensure that that is set as the default branch

* fixup

* fixup

* Missed HookOptions in setdefaultbranch

* Batch PushUpdateAddTag and PushUpdateDelTag
