[PATCH 0/3] string: import strverscmp_improved from systemd

[Ahmad Fatoum]

The Boot Loader specification now references the UAPI group's version
format specification[1] on how blspec entries should be sorted.

In preparation of aligning barebox entry sorting with the specification,
import systemd's strverscmp_improved as strverscmp and add some tests
for it.

The changes to bootloader spec sorting need some more testing and will
follow separately.
