This commit removes the version selection for the busybox
package. Busybox is very well maintained, and bugs are typically fixed
in a timely fashion. Moreover, regressions are fairly unlikely in this
very stable and well-tested tool.
Therefore, there isn't a very compelling reason to have a version
selection for Busybox since we don't accept such a version selection
for the vast majority of other packages, unless there is a strong
reason to do so.
Consequently, this commit:
* Removes the 1.19.4, 1.20.2 and 1.21.1 Busybox versions, patches and
default configuration file.
* Moves the 1.22.1 patches from package/busybox/1.22.1 to just
package/busybox/ like all other packages.
* Renames the default 1.22.1 configuration file to just
busybox.config.
* Adapts the busybox.mk makefile to encode the current version to
use.
* Adds appropriate options to Config.in.legacy. However, even though
the BR2_BUSYBOX_VERSION_1_22_X is removed, we don't add a
Config.in.legacy option for it, since it would cause a legacy
warning for virtually *all* users as most people are currently
using 1.22.x.
