The idea of this version is to have two notations, one which shadows the bad definition `Strings.length` and the other which shadows the bad Notation `List.length`, which is bad because it is parsing only.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/143Add tests for equiv notation2020-04-10T05:58:08ZPaolo G.

I very much dislike the statement of `list_find_insert_Some`, but I cannot come up with anything better that is true.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/133Remove trailing whitespace2020-03-31T08:07:03ZMichael SammlerRemove trailing whitespaceThis was done using `sed --in-place 's/[[:space:]]\+$//' theories/*.v`.This was done using `sed --in-place 's/[[:space:]]\+$//' theories/*.v`.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/132Replace explicit use of Inj instances by inj2020-03-31T13:36:25ZPaolo G.

@msammler and I figured out how to change the imports to fix this problem without the hack. Basically, `stdpp.base` exports `Coq.Strings` and `Coq.List` in the right order, so the shadowing is done right. As a consequence `Coq.Strings` should never be exported by hand.
This approach seems to work among all supported Coq versions.
