Register approval for a dispatch to be made from a deterministic composite account if
approved by a total of threshold - 1 of other_signatories.
Payment: DepositBase will be reserved if this is the first approval, plus
threshold times DepositFactor. It is returned once this dispatch happens or
is cancelled.
The dispatch origin for this call must be Signed.
threshold: The total number of approvals for this dispatch before it is executed.
other_signatories: The accounts (other than the sender) who can approve this
dispatch. May not be empty.
maybe_timepoint: If this is the first approval, then this must be None. If it is
not the first approval, then it must be Some, with the timepoint (block number and
transaction index) of the first approval transaction.
call_hash: The hash of the call to be executed.
NOTE: If this is the final approval, you will want to use as_multi instead.
Complexity
O(S).
Up to one balance-reserve or unreserve operation.
One passthrough operation, one insert, both O(S) where S is the number of
signatories. S is capped by MaxSignatories, with weight being proportional.
One encode & hash, both of complexity O(S).
Up to one binary search and insert (O(logS + S)).
I/O: 1 read O(S), up to 1 mutate O(S). Up to one remove.
One event.
Storage: inserts one item, value size bounded by MaxSignatories, with a deposit
taken for its lifetime of DepositBase + threshold * DepositFactor.
