Abandon ROCKSDB_WARNING

Summary:
My latest fix to pragma_error.h caused compilation errors for another internal project.  I am now unable to figure out how to get pragma_error working on all platforms and build environments (nor am I able to test any other options).

Seems like the best option is to get rid of this macro.  include/utilities has been deprecated for a year now, so lets just deal with a breaking change in 3.13 to remove these files.  And I guess we'll have to live with having an extra convenience.h.

Thoughts?

Test Plan: build
