Rework
dnf_repo_substitute
to call the C++ API'sConfigParser::substitute
instead of librepo'slr_url_substitute
. This brings support for shell-style variable expressions to the C API, which was added to the C++ API in #1622.We could instead add support for the shell-style variable substitution in librepo's
lr_url_substitute
, which might have additional benefits elsewhere, but it would take more development time, risk breaking something, and create yet another implementation of this feature.Resolves #1690.
