Subject: Annotate some static locals as "library-local"
X-Git-Tag: v2016.11.07.00

Annotate some static locals as "library-local"

Summary:
This tags certain static locals, wich may get duplicated via dynamic
linking and inlining, as safe to have multiple copies at runtime,
making this subtle behavior explicit.
