lib: add static identifier codes for all deprecations

Assigns a static identifier code to all runtime and documentation
only deprecations. The identifier code is included in the emitted
DeprecationWarning.

Also adds a deprecations.md to the API docs to provide a central
location where deprecation codes can be referenced and explained.
