ARROW-6214: [R] Add R sanitizer docker image The PR creates a docker image to replicate R sanitizer errors. One can iterate with arrow local sources without installing CRAN arrow package. A real undefined behaviour was fixed in `array_to_vector.cpp`. The other errors were false positives (to best of my knowledge). Closes #5408 from fsaintjacques/ARROW-6214-r-sanitizer and squashes the following commits: e85c7e375 <François Saint-Jacques> Add docker-r-sanitizer to nightly tasks 7209ca922 <François Saint-Jacques> Fix UBSAN pointer casting error 6b425b4ae <François Saint-Jacques> ARROW-6214: Add sanitizer docker image Authored-by: François Saint-Jacques <fsaintjacques@gmail.com> Signed-off-by: Neal Richardson <neal.p.richardson@gmail.com>
