[API]: "Private" (imported) Python APIs used in across other RAPIDS projects

[mroeschke]

This is the result of a quick audit and does not include private APIs on public objects e.g. cudf.Series._column

TLDR observations:

1. There seems to be a common desire to create a Column object (this might be solved with pylibcudf)?
2. There seems to be a secondary desire to create a Buffer object

[bdice]

Almost everything from _lib (which also means "almost everything using cudf Cython via cimport") will have a mirror image in pylibcudf. In the short term I would focus efforts on the uses of cudf.core, and let cudf._lib be resolved at a later time as pylibcudf matures.
