mempool: Removed the ancestor_score index
Summary
This MR depends on !1078 (merged), !1118 (merged) and !1080 (merged).
This commit removes the index for ancestor_score
and the comparator CompareTxMemPoolEntryByAncestorFee
, since after !1078 (merged) and !1080 (merged) are merged it will no longer be needed.
This index was previously used for CPFP mining, which we no longer do after !1078 (merged).
Test Plan
Nothing is using this index now after !1078 (merged) , other than unit test code to test this index, which has been removed.
ninja check check-functional
Note to reviewers
You should just review the top-most commit. The other commits are just the commits from !1078 (merged), !1080 (merged), and !1118 (merged) !
