Superseding Delegated Rotation and misfit escrow (WebOfTrust#680)

* renamed tests

* created test to test supersedeing logic. Just setting up for now not done.

* setting up superseding delegation tests

* more work on superseding test

* add more to supersede test work, plus some cleanup

* added detailed doc string on acceptance rules for delegated events
added cleanup of cue triggers

* more details in doc string

* fixed clarification

* added additional doc string language

* fixed typo

* updated superseding logic to include virtual delegating event when local delegator is processing delegated event acceptance into its local copy of delegatees KEL so as not to corrupt its copy.

* updated doc string

* more doc string goodness

* some refactoring. remaned Kever.delegator to .delpre to follow convention
and the uses renamed.

* added event source record Komer .esrs subdb to Baser so we can track source of event local or remote

* Passing event source to processEvent from all escrow processing routines.

Signed-off-by: pfeairheller <[email protected]>

* updated doc string for Baser for .esrs subdb

* rebasing misfit

Signed-off-by: pfeairheller <[email protected]>

* Add local persistence to escrowing methods.

Signed-off-by: pfeairheller <[email protected]>

* added code in Kever to update event source record

* changed parser logic to support local

* Fix processEscrow events to use correct key for esr

Signed-off-by: pfeairheller <[email protected]>

* updated keys for .esrs usage

* clean up fix merge fail

* added misfit event escrow database .mfes as CesrIoSetSuber instance.

* habery .__init__ creates its default .psr parser with local = True

* added method to Kevery.escrowMFEvent for escrowing misfit events into .mfes

* rebasing misfit

Signed-off-by: pfeairheller <[email protected]>

* fixed unit test and logic for misfit processing

* some clean up refactor in Kever. Added local parameter to process receipt methods in Kevery.

* some cleanup on doc strings and comments

* updated locallyWitnessed to return boolean

* Fix tests that parse events with a lax Kevery to now use `local=true` in the call to parse.

Signed-off-by: pfeairheller <[email protected]>

* removed redundant misfit checks refactored .locallWitnessed method other clean up

* removed potentially buggy redundant inject of db.prefixes into Kever.prefixes as attribute and replaced with property that uses .db.prefixes instead

* added Baser.gids as oset of Group Hab pres (hids)

* changed Baser.mfes to .misfits since CesrIoSetSuber attribute name does not need to match subkey .mfes
x

* added test for prefix in locallyOwned to not be in db.groups.
Changes db.gids to .groups

* some refactor of methos names to distinquish processing of the attached equivalent of receipt versus the actual rct messages
enabled the new local pass in from parser for rct messages.

* added code to filter out local signatures for group messages received remotely (nonlocal not protected)

* refactor Kever.locallyOwned to default to self.prefixer.qb64 if no prefix passed in

* updated code comment

* added cue for remoteMemberedSig to notify when recieving own signature on group multisig event from unprotected source

* refactor logic to set stage for delegation escrow to do the approval of delegation by delegator and any sandboxing
needed or cues to business logic for approval.

* added db Baser.delegables subkey .dees for delegable escrowed events awaiting delegator approval.
Still needs processDelegableEscrows but now Kever escrows them

* updated comments

* rebasing misfit

Signed-off-by: pfeairheller <[email protected]>

* started changing Number class

* more unit texts for Number

* added .validate method to Number to validate if number is ordinal

* added more tests. Replaced some Seqner usages

* cleanup Seqner and tests
Added .seqner property to Number and tests

* removed validateSN function. replaced with Number.validate

* Fix delegator escrow test to match new expectation that delegate have delegator's pre in kevers.

Signed-off-by: pfeairheller <[email protected]>

* Comment delegation script until kli delegation commands can be fixed.
