* More POSIX ports (`pkg_tools`, `conda`, `tlmgr`,
  `dnf`, `swupd`, `yum`, `macports`)

Changes since v2.4.4:

* `lib/opkg`: Add support for `OpenWrt` (and alike)
* `Bash` is not required on `Alpine`, `SunOS` or `OpenWrt`:
  The proram can work perfectly with `POSIX` shell on those systems.
* Single script can now execute within `POSIX` or `non-POSIX`
  environment and it detects/loads features dynamically.
  If the system has `bash` installed, the program switches to
  `bash` as soon as possible.

* `tests/`: Support new `ubuntu`/`debian` systems
* `lib/yum`, `lib/dpkg`, `lib/apk`: Fix #96, #143
  by adding  `-q` (quiet) option for `Qs`.
* `lib/00_core.sh`: POSIX going well
* `lib/zz_main.sh`: POSIX going well
* `lib/apk`:
  * Fix many implementation issues.
  * `Q` prints version information.
  * Fix `--noconfirm` issue (#150)
  * POSIX version (`pacapt-POSIX` works perfectly without `bash`)
* Remove `{apk,dnf,zypper}_Sw` methods
  and fix the `--download-only` for them

Changes since v2.4.3:

* `lib/dnf`: Minor improvements (#148)
