Summary:
Ref T5245. See some discussion in D9838.
When we attach object A to object B, we'd like to write transactions on both sides but only write the actual edges once.
To do this, allow edge types to `shouldWriteInverseTransactions()`. When an edge type opts into this, have editors apply the inverse transactions before writing the edge. These inverse transactions don't actually apply effects, they just show up in the transaction log.
Test Plan: Attached and detached revisions from tasks, saw transactions appear on both sides of the operation.

Summary:
Patches often read from slaves (possibly stale data) and use that information to write on master.
It causes problems when applying more patches quickly after each other because data created in previous patch may not be replicated yet.
Test Plan:

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.
