Changes in Rcpp patch release version 1.0.6 (2021-01-14)

  - Changes in Rcpp API:
      * Replace remaining few uses of EXTPTR_PTR with R_ExternalPtrAddr (Kevin
        in #1098 fixing #1097).
      * Add push_back and push_front for DataFrame (Walter Somerville in #1099
        fixing #1094).
      * Remove a misleading-to-wrong comment (Mattias Ellert in #1109 cleaning
        up after #1049).
      * Address a sanitizer report by initializing two private bool variables
        (Benjamin Christoffersen in #1113).
      * External pointer finalizer toggle default values were corrected to true
        (Dirk in #1115).
  - Changes in Rcpp Documentation:
      * Several URLs were updated to https and/or new addresses (Dirk).
  - Changes in Rcpp Deployment:
      * Added GitHub Actions CI using the same container-based setup used
        previously, and also carried code coverage over (Dirk in #1128).
  - Changes in Rcpp support functions:
      * Rcpp.package.skeleton() avoids warning from R. (Dirk)
