Feature/tinytest

[eddelbuettel]

This switches Rcpp from RUnit to tinytest, similar to the conversion in a done of other repos.

Checklist

• Code compiles correctly
• R CMD check still passes all tests
• Document the changes by file in ChangeLog

@kevinushey @jjallaire -- if you have a chance to review, I would appreciate it.

This "only" moves us from RUnit to tinytest, removing one helper file in R/ (to approximate poorly what tinytest gives us for free, tests from the installed package) but has of course a lot of changes in inst/tinytest relative to inst/unitTests.

There is a bit more tuning to do -- I am currently "parking" tests that create a lot of noise on the command-line (test of package installation) and I think I want to make those conditional on a new env var just how we now have one that turns on/off with majors like 1.0.3 ("off") or 1.0.3.2 ("on"). If the var is set, doing tinytest::run_test_dir("inst/tinytest/") gives you this:

Similarly, tinytest::test_package("Rcpp", ncpu=4) runs the installed package.

There is also a little bit of 'crayon'-style color. Here is what testing the installed package looks like:
