find-deprecated-pkgs: major upgrade, rename to find-deprecated

ChangeLog:
* split custimizable find-deprecated-pkgs variables into configuration file
* update copyright years
* create a mkmirrorlist() function to better handle mirrors
* check arguments with $# instead of ${#@}
* declare local variables in functions instead of unsetting them at the end
* rename check() to main()
* create mkpkglist_from_mirror() function
* remove mkpkglist()
* code optimizations
* fail if connection to specific mirror fails
* remove $netcheck

+# Find deprecated Arch packages that are still in our blacklists.
+# shellcheck disable=SC2154
+
+usage(){
+  # NOTE: the package architecture is always specified with 'parabola', and
+  # in 'arch' only when there's an uneeded replacement. This is because your-freedom
+  # is for any architecture and no matter if you use Parabola x86_64 or i686, it
+  # will always conflict packages that are even for armv7h only (and vice versa).
+  # The 'parabola' argument compares with our repositories and Arch's
+  # since in blacklists like your-privacy and your-initfreedom we also block
+  # some packages from [pcr] (like jitsi) and [libre] (like icedove), and
+  # probably also from their -multilib, -testing and -multilib-testing derivatives.
+
+  cat <<EOM
+Usage: ${0##*/} [arch|parabola]
+Check if there are inexistent packages in the blacklists.
+
+Arguments:
+  arch                        Compares ArchLinux{32,ARM} blacklists with their
+                              repositories.

+                              and Arch's repos.
+
+Configuration is read from a file called find-deprecated.conf in the same directory
+as this script.
+
+To easily remove a package from a blacklist, you can use the following sed expresion:
